* drm: omapdrm: dss: Pass PLL pointer to dss_ctrl_pll_enable()Laurent Pinchart2018-03-01

* drm: omapdrm: dss: Pass DSS private structure to runtime PM functionsLaurent Pinchart2018-03-01
| | | | | | | | | | | | | | To prepare for the removal of the global variable storing DSS private data, pass its pointer to the dss_runtime_{get,put}() functions. As this requires getting hold of the dss_device structure in the callers, we add a new dss_get_device() function to retrieve it. The function currently returns a pointer to the global data structure, and will later be updated to get the pointer from device driver data when the DSS private structure will be allocated dynamically.

* drm: omapdrm: dss: Expose DSS data in a dss_device structureLaurent Pinchart2018-03-01
| | | | | | | | | | | | | | | The anoonymous dss structure in dss.c is the top-level component in the omapdss driver. As such it should store all internal instance-specific data that is currently stored in global variables. This however requires both naming the structure to pass it around functions, and accessing it from various locations in the omapdss driver. While we could implement get and set functions for every field that needs to be accessed outside of dss.c, that would introduce overhead and complexity that we could avoid by exposing the structure to internal components of the omapdss driver. Do so to prepare for removal of global variables. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
* drm: omapdrm: Split init and cleanup from probe and remove functionsLaurent Pinchart2018-03-01
| | | | | | | | | | | When merging the omapdrm and omapdss drivers there will be not omapdrm platform device anymore, and thus no associated probe and remove functions. To prepare for that, split all the initialization code from the probe function to make it usable without a platform device. Similarly, split the cleanup code from the remove function.

| | | | | | | | | | | | The wait_for_bit_change() function returns the value of the bit it polls. This requires the caller to compare the return value to the expected bit value. As all the existing callers need is to check whether the bit has reached the expected value, it's easier to return a boolean status from the function.

* drm: omapdrm: dss: Move initialization code from component bind to probeLaurent Pinchart2018-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no reason to delay initialization of most of the driver (such as mapping memory I/O, getting clocks or enabling runtime PM) to the component master bind handler. This additionally fixes a real PM issue caused enabling runtime PM in the bind handler. The bind handler performs the following sequence of PM operations: pm_runtime_enable(dev); pm_runtime_get_sync(dev); ... (access the hardware to read the device revision) ... pm_runtime_put_sync(dev); If a failure occurs at this point, the error path calls pm_runtime_disable() to balance the pm_runtime_enable() call. To understand the problem, it should be noted that the bind handler is called when one of the component registers itself, which happens in the component's probe handler. Furthermore, as the components are children of the DSS, the device core calls pm_runtime_get_sync() on the DSS platform device before calling the component's probe handler. This increases the DSS power usage count but doesn't runtime resume the device, as runtime PM is disabled at that point. The bind handler is thus called with runtime PM disabled, with the device runtime suspended, but with the power usage count larger than 0. The pm_runtime_get_sync() call will thus further increase the power usage count and runtime resume the device. The pm_runtime_put_sync() handler will decrease the power usage count to a non-zero value and will thus not suspend the device. Finally, the pm_runtime_disable() call will disable runtime PM, preventing the pm_runtime_put() call in the device core from runtime suspending the device. The DSS device is thus left powered on. To fix this, move the initialization code from the bind handler to the probe handler.

| * omapdrm/dss/hdmi4_cec: fix interrupt handlingHans Verkuil2018-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omap4 CEC hardware cannot tell a Nack from a Low Drive from an Arbitration Lost error, so just report a Nack, which is almost certainly the reason for the error anyway. This also simplifies the implementation. The only three interrupts that need to be enabled are: Transmit Buffer Full/Empty Change event: triggered when the transmit finished successfully and cleared the buffer. Receiver FIFO Not Empty event: triggered when a message was received. Frame Retransmit Count Exceeded event: triggered when a transmit failed repeatedly, usually due to the message being Nacked. Other reasons are possible (Low Drive, Arbitration Lost) but there is no way to know. If this happens the TX buffer needs to be cleared manually. While testing various error conditions I noticed that the hardware can receive messages up to 18 bytes in total, which exceeds the legal maximum of 16. This could cause a buffer overflow, so we check for this and constrain the size to 16 bytes. The old incorrect interrupt handler could cause the CEC framework to enter into a bad state because it mis-detected the "Start Bit Irregularity event" as an ARB_LOST transmit error when it actually is a receive error which should be ignored.
