* [media] em28xx: support for Hauppauge WinTV-dualHD 01595 ATSC/QAMKevin Cheng2017-02-03
| | | | | | | | | | | | | | Hauppauge WinTV-dualHD model 01595 is a USB 2.0 dual ATSC/QAM tuner with the following components: USB bridge: Empia em28274 Demodulator: 2x LG LGDT3306a at addresses 0xb2 and 0x1c Tuner: 2x Silicon Labs si2157 at addresses 0xc0 and 0xc4 This patch enables only the first tuner.

* [media] em28xx: don't store usb_device at struct em28xxMauro Carvalho Chehab2016-12-12
| | | | | | | | Now that we're storing usb_interface at em28xx struct, there's no good reason to keep storing usb_device, as we can get it from usb_interface. So, get rid of it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| | | | | | | | | | | Instead of using pr_foo(), use dev_foo(), with provides a better output. As this device is a multi-interface one, we'll set the device name to show the chipset and the driver used. While here, get rid of printk continuation messages.

| | | | | | | | | | | | There are still several places with printk's called directly. Convert them to pr_foo() macros, except for the debug printk's, as those are enabled via modprobe vars.

* [media] em28xx: add support for Hauppauge WinTV-dualHD DVB tunerOlli Salonen2016-05-09
| | | | | | | | | | | | | | | | | | | | | Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with following components: USB bridge: Empia EM28274 (chip id is the same as EM28174) Demodulator: 2x Silicon Labs Si2168-B40 Tuner: 2x Silicon Labs Si2157-A30 This patch adds support only for the first tuner. The demodulator needs firmware, available for example here: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/ The demodulators sit on the same I2C bus and their addresses are 0x64 and 0x67.

* [media] cx231xx, em28xx: pass media_device to si2157Mauro Carvalho Chehab2016-02-16
| | | | | | | | | | | As si2157 doesn't use the subdev, but has instead a binding logic that doesn't have any core framework, we need to manually pass the media_device struct via platform data on every place it is called.

This patch adds support for the cards carrying the mt2060 tuner; it's unclear whether there are cards sold under the same name which use a different tuner. As long as there are no reports of such cards, and indeed as long as there are no working drivers for them, we assume that the USB device [0ccd:0043] is carrying the mt2060 tuner.

| | | | | | | | | | | | | | | | | | | This patch is basically produced while testing a tool that Joe Perches sent upstream sometime ago: https://lkml.org/lkml/2014/7/11/794 I used it with those arguments: $ reformat_with_checkpatch.sh drivers/media/usb/em28xx/em28xx*.[ch] It actually produced 24 patches, with is too much, and showed interesting things: gcc produced different codes on most of the patches, even with just linespace changes.
