From 40eca140c404505c09773d1c6685d818cb55ab1a Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 14 Feb 2016 00:41:06 -0200 Subject: [media] mn88473: add DVB-T2 PLP support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds PLP ID filtering for DVB-T2. It is untested as I don't have any signal having PLP ID other than 0. There is only 2 extra registers, 0x32 and 0x36 on bank2, that are programmed for DVB-T2 but not for DVB-T and all the rest are programmed similarly - so it is likely PLP. Pridvorov reported successfully testing it in Russia with m-PLP streams, on both Vladivostok and Moskow.

The reason is two-fold: the pipeline struct is, rightly, already called media_pipeline (rather than media_entity_pipeline) and what this really is about is a pipeline. A pipeline consists of entities --- and, well, other objects embedded in these entities. As the pipeline object will be in the future moved from entities to pads in order to support multiple pipelines through a single entity, do the renaming now. Similarly, functions operating on struct media_entity_graph as well as the struct itself are renamed by dropping the "entity_" part from the prefix of the function family and the data structure. The graph traversal which is what the functions are about is not specifically about entities only and will operate on pads for the same reason as the media pipeline. The patch has been generated using the following command: git grep -l media_entity |xargs perl -i -pe ' s/media_entity_pipeline/media_pipeline/g; s/media_entity_graph/media_graph/g' And a few manual edits related to line start alignment and line wrapping.

Even with the current implementation of the kthread the only lost wakeup scenario could happen if the wakeup occurs between the kfifo_len check and setting the state to TASK_INTERRUPTIBLE. In the changed version we could lose a wakeup if it occurs between processing the fifo content and setting the state to TASK_INTERRUPTIBLE. This scenario is covered by an additional check for available events in the fifo and setting the state to TASK_RUNNING in this case. In addition the changed version flushes the kfifo before ending when the kthread is stopped. With this patch we gain: - Get rid of the spinlock - Simplify code - Don't grep / release the mutex for each individual event but just once for the complete fifo content. This reduces overhead if a driver e.g. triggers processing after writing the content of a hw fifo to the kfifo.

In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

So this format reverses the 4 bytes. There are arguments to be had for both formats, but we should not use different formats in different parts of the kernel. Selecting the second format introduces the least code churn. It does mean that the TiVo keymap needs updating. This change was submitted before as "18bc174 [media] media: rc: change 32bit NEC scancode format", which was reverted because it was unclear what scancode rc drivers produce. There are now more examples of drivers which produce nec32 in lsb format. The TiVo keymap is verified against the Nero Liquid TiVo remote. The keymap is not for the Tivo DVR remote, which uses rc-5.

This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value.

The driver, indeed, uses the SPI framework to stream the raw data provided by userspace through an rc character device. The chardev is handled by the LIRC framework and its functionality basically provides: - write: the driver gets a pulse/space signal and translates it to a binary signal that will be streamed to the IR led through the SPI framework. - set frequency: sets the frequency whith which the data should be sent. This is handle with ioctl with the LIRC_SET_SEND_CARRIER flag (as per lirc documentation) - set duty cycle: this is also handled with ioctl with the LIRC_SET_SEND_DUTY_CYCLE flag. The driver handles duty cycles of 50%, 60%, 70%, 75%, 80% and 90%, calculated on 16bit data. The character device is created under /dev/lircX name, where X is and ID assigned by the LIRC framework. Example of usage: fd = open("/dev/lirc0", O_RDWR); if (fd < 0) return -1; val = 608000; ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val); if (ret < 0) return -1; val = 60; ret = ioctl(fd, LIRC_SET_SEND_DUTY_CYCLE, &val); if (ret < 0) return -1; n = write(fd, buffer, BUF_LEN); if (n < 0 || n != BUF_LEN) ret = -1; close(fd); Signed-off-by: Andi Shyti Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab --- drivers/media/rc/Kconfig | 9 +++ drivers/media/rc/Makefile | 1 + drivers/media/rc/ir-spi.c | 199 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 209 insertions(+) create mode 100644 drivers/media/rc/ir-spi.c (limited to 'drivers/media') diff --git a/drivers/media/rc/Kconfig b/drivers/media/rc/Kconfig index 629e8ca15ab3..3351e25d6176 100644 --- a/drivers/media/rc/Kconfig +++ b/drivers/media/rc/Kconfig @@ -261,6 +261,15 @@ config IR_REDRAT3 To compile this driver as a module, choose M here: the module will be called redrat3. +config IR_SPI + tristate "SPI connected IR LED" + depends on SPI && LIRC + ---help--- + Say Y if you want to use an IR LED connected through SPI bus. + + To compile this driver as a module, choose M here: the module will be + called ir-spi. + config IR_STREAMZAP tristate "Streamzap PC Remote IR Receiver" depends on USB_ARCH_HAS_HCD diff --git a/drivers/media/rc/Makefile b/drivers/media/rc/Makefile index 3a984ee301e2..938c98b82b22 100644 --- a/drivers/media/rc/Makefile +++ b/drivers/media/rc/Makefile @@ -27,6 +27,7 @@ obj-$(CONFIG_IR_NUVOTON) += nuvoton-cir.o obj-$(CONFIG_IR_ENE) += ene_ir.o obj-$(CONFIG_IR_REDRAT3) += redrat3.o obj-$(CONFIG_IR_RX51) += ir-rx51.o +obj-$(CONFIG_IR_SPI) += ir-spi.o obj-$(CONFIG_IR_STREAMZAP) += streamzap.o obj-$(CONFIG_IR_WINBOND_CIR) += winbond-cir.o obj-$(CONFIG_RC_LOOPBACK) += rc-loopback.o diff --git a/drivers/media/rc/ir-spi.c b/drivers/media/rc/ir-spi.c new file mode 100644 index 000000000000..c8863f36686a --- /dev/null +++ b/drivers/media/rc/ir-spi.c @@ -0,0 +1,199 @@ +/* + * Copyright (c) 2016 Samsung Electronics Co., Ltd. + * Author: Andi Shyti + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * SPI driven IR LED device driver + */ + +#include +#include +#include +#include +#include +#include +#include +#include + +#define IR_SPI_DRIVER_NAME "ir-spi" + +/* pulse value for different duty cycles */ +#define IR_SPI_PULSE_DC_50 0xff00 +#define IR_SPI_PULSE_DC_60 0xfc00 +#define IR_SPI_PULSE_DC_70 0xf800 +#define IR_SPI_PULSE_DC_75 0xf000 +#define IR_SPI_PULSE_DC_80 0xc000 +#define IR_SPI_PULSE_DC_90 0x8000 + +#define IR_SPI_DEFAULT_FREQUENCY 38000 +#define IR_SPI_BIT_PER_WORD 8 +#define IR_SPI_MAX_BUFSIZE 4096 + +struct ir_spi_data { + u32 freq; + u8 duty_cycle; + bool negated; + + u16 tx_buf[IR_SPI_MAX_BUFSIZE]; + u16 pulse; + u16 space; + + struct rc_dev *rc; + struct spi_device *spi; + struct regulator *regulator; +}; + +static int ir_spi_tx(struct rc_dev *dev, + unsigned int *buffer, unsigned int count) +{ + int i; + int ret; + unsigned int len = 0; + struct ir_spi_data *idata = dev->priv; + struct spi_transfer xfer; + + /* convert the pulse/space signal to raw binary signal */ + for (i = 0; i < count; i++) { + int j; + u16 val = ((i + 1) % 2) ? idata->pulse : idata->space; + + if (len + buffer[i] >= IR_SPI_MAX_BUFSIZE) + return -EINVAL; + + /* + * the first value in buffer is a pulse, so that 0, 2, 4, ... + * contain a pulse duration.

Two of those have a VFD and two don't. The VFD code is exactly the same in the mainline imon driver, so that part is easily ported. The staging driver produces raw IR rather than scancodes for the four devices, so I've ported the raw IR code from staging to mainline imon. Now that mainline imon can handle these four devices, lirc_imon is no longer needed. Compile tested only.

When probing the driver through DT these fields are not explicitly initialized, which means they are left at 0. This is a reserved setting for the drive strength configuration though and can cause signal integrity issues. Whether these signal integrity issues are visible depends on the PCB specifics (e.g. the higher the load capacitance for the output the more visible the issue). But it has been observed on existing solutions at high pixel clock rates. Initialize the drive strength settings to the power-on-reset value of the device when probing through devicetree to avoid this issue.

If and only if the VDOA is available, the driver can also provide YUYV support. While the driver is configured to produce YUYV output, the CODA must be configured to produce NV12 macroblock tiled frames and the VDOA must transform the intermediate result into the final YUYV output.

Each time a running instance is closed, its context (including the debug information) is saved to feed, on demand, the last closed instance debugfs entry.

That has very huge effect for power management, around 0.9W. Sleep is still disabled for all the old hardware just to avoid possible regression as meaning of register bits are unknown. I tested it also with some other devices and it seems to be working, but I still consider it to be too risky to change it default.

Since then, the usage of the the DVB APIs is deprecated. However, we never actually marked it as deprecated nor provided any way to disable it. Let's do it now.

It has worked fine with all the sources we and our customers has used, until it was reported problems with Apple MacBook (Retina, 12-inch, Early 2015) (https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US) with Apple A1612 USB type-C multiport adapter (http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter) Finally Toshiba came up with a hidden bit that is named "Manual HDCP authentication". In this patch the original "repeater mode" concept is removed, and the new bit is set instead. With his patch HDCP is disabled when connected to the Apple MacBook and all other sources we have tested so far. The Apple MacBook is constantly trying to authenticate, but fails and continues to transmit unencrypted video.

If the internal ADC is used, or if audio is disabled altogether, there's no point trying to setup the AC97 codec.

For example, v4l2_async_test_notify() moved a subdev into notifier's done list even if registering the subdev (v4l2_device_register_subdev) failed. If the subdev was allocated and v4l2_async_register_subdev() called from the driver's probe() function, as usually, the probe() function freed the allocated subdev and returned a failure. Nevertheless, the subdev was still left into the notifier's done list, causing an access to already freed memory when the notifier was later unregistered. A hand-edited call trace leaving freed subdevs into the notifier: v4l2_async_register_notifier(notifier, asd) cameradrv_probe sd = devm_kzalloc() v4l2_async_register_subdev(sd) v4l2_async_test_notify(notifier, sd, asd) list_move(sd, ¬ifier->done) v4l2_device_register_subdev(notifier->v4l2_dev, sd) cameradrv_registered(sd) -> fails ->v4l2_async_register_subdev returns failure ->cameradrv_probe returns failure ->devres frees the allocated sd ->sd was freed but it still remains in the notifier's list. This patch fixes this and several other cases where a failing function could leave nodes into a linked list while the caller might free the node due to a failure.

Based on 4 services open/set_stream/decode/close and their associated rpmsg messages. The messages structures are duplicated on both host and firmware side and are packed (use only of 32 bits size fields in messages structures to ensure packing). Each service is synchronous; service returns only when firmware acknowledges the associated command message. Due to significant parameters size exchanged from host to copro, parameters are not inserted in rpmsg messages. Instead, parameters are stored in physical memory shared between host and coprocessor. Memory is non-cacheable, so no special operation is required to ensure memory coherency on host and on coprocessor side. Multi-instance support and re-entrance are ensured using host_hdl and copro_hdl in message header exchanged between both host and coprocessor. This avoids to manage tables on both sides to get back the running context of each instance.

To do so, user calls VIDIOC_DECODER_CMD(V4L2_DEC_CMD_STOP) which will drain the decoder and get the drained frames that are then returned to user. User is informed of EOS completion in two ways: - dequeue of an empty frame flagged to V4L2_BUF_FLAG_LAST - reception of a V4L2_EVENT_EOS event. If, unfortunately, no buffer is available on CAPTURE queue to return the empty frame, EOS is delayed till user queue one CAPTURE buffer.
