SH4 7724 Ecovec platform uses sh_mobile_ceu camera driver, which is now being replaced by a proper V4L2 camera driver named 'renesas-ceu'. Get rid of soc_camera defined components used to register sensor drivers and of platform specific enable/disable routines. Register GPIOs for sensor drivers and declare memory reserved with memblock APIs as dma capable to be used for CEU buffers. While at there re-order include directives to respect alphabetical ordering. Signed-off-by:

Remove soc_camera framework dependencies from mt9t112 sensor driver. - Handle clk, gpios and power routines - Register async subdev - Remove deprecated g/s_mbus_config operations - Remove driver flags - Change driver interface and add kernel doc - Adjust build system - Fix code style issues reported by checkpatch in strict mode This commit does not remove the original soc_camera based driver as long as other platforms depends on soc_camera framework. As I don't have access to a working camera module, this change has only been compile tested. Signed-off-by:

Copy the soc_camera based driver in v4l2 sensor driver directory. This commit just copies the original file without modifying it. No modification to KConfig and Makefile as soc_camera framework dependencies need to be removed first in next commit. Signed-off-by:

Replace static stream settings by one which enables and disables stream interface when needed (TS streaming control). 1) Configure both TS IF and USB endpoints according to current use case 2) Disable streaming USB endpoints when streaming is stopped and enable when streaming is started. Reduces sleep power consumption slightly. 3) Reduce USB buffersize slightly, from 130848 to 98136 bytes Signed-off-by:

media: mceusb: add IR learning support features (IR carrier frequency measurement and wide-band/short-range receiver) Windows Media Center IR transceivers include two IR receivers; wide-band/short-range and narrow-band/long-range. The short-range (5cm distance) receiver is for IR learning and has IR carrier frequency measuring ability. Add mceusb driver support to select the short range IR receiver and enable pass through of its IR carrier frequency measurements. RC and LIRC already support these mceusb driver additions.

A timeout of 200ms is much longer than necessary, and delays the decoding decoding of a single scancode and the last scancode when a button is being held. This makes the remote seem sluggish. If the min_timeout and max_timeout values are set, the timeout is configurable via the LIRC_SET_REC_TIMEOUT ioctl. Tested-by:

Meson doesn't seem to be able to generate timeout events in hardware. So install a software timer to generate the timeout events required by the decoders to prevent "ghost keypresses". Reported-by:

The ADV7604 has thirteen 256-byte maps that can be accessed via the main I2C ports. Each map has it own I2C address and acts as a standard slave device on the I2C bus. Allow a device tree node to override the default addresses so that address conflicts with other devices on the same bus may be resolved at the board description level.

The ADV748x has 12 pages mapped onto I2C addresses. In the existing implementation only 11 are mapped correctly in the page enumerations, which causes an off-by-one fault on pages above the infoframe definition due to a missing 'CBUS' page. This causes the address for the CEC, SDP, TXA, and TXB to be incorrectly programmed during the iterations in adv748x_initialise_clients(). Until now this has gone un-noticed due to the fact that following the creation of the clients - the device is reset and the addresses are reprogrammed in manually by the call to "adv748x_write_regs(state, adv748x_set_slave_address);" As part of moving to dynamic i2c address allocations repair this by providing the missing CBUS page definition.

The v4l2_subdev core s_power op was used for two different things: power on/off sensors or video decoders/encoders and to put a tuner in standby (and only the tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner is accessed. The danger with calling (s_power, 0) to put a tuner into standby is that it is usually broadcast for all subdevs. So a video receiver subdev that supports s_power will also be powered off, and since there is no corresponding (s_power, 1) they will never be powered on again. In addition, this is specifically meant for tuners only since they draw the most current. This patch adds a new tuner op called 'standby' and replaces all calls to (core, s_power, 0) by (tuner, standby). This prevents confusion between the two uses of s_power. Note that there is no overlap: bridge drivers either just want to put the tuner into standby, or they deal with powering on/off sensors. Never both. This also makes it easier to replace s_power for the remaining bridge drivers with some PM code later. Whether we want something cleaner for tuners in the future is a separate topic. There is a lot of legacy code surrounding tuners, and I am very hesitant about making changes there. Signed-off-by:
