Implement dvbv5 signal strength estimate. We know tuner dependent -80dBm and -50dBm agc values, construct line equation and use it to map agc value to signal strength estimate. Signed-off-by:

Whilst rewritten largely, the basic logic remains same with one exception: do not return immediately on success case. We are going to add statistics that function and cannot return too early. 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 ADV748x has identical map configurations for each register map. The duplication of each map can be simplified using a helper macro such that each map is represented on a single line. Define ADV748X_REGMAP_CONF for this purpose use it to create the tables. Signed-off-by:

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:

Do not stop/restart dma on overrun or errors. Dma will be restarted on current frame transfer completion. Frame transfer completion is ensured even if overrun or error occurs by DCMI continuous capture mode which restarts data transfer at next frame sync. Do no warn on overrun while in irq thread, this slows down system and lead to more overrun errors. Use a counter instead and log errors at stop streaming. Signed-off-by:

Add a function (as well as a helper macro) to obtain the best size in a list of device specific sizes. This helps writing drivers as well as aligns interface behaviour across drivers. The struct in which this information is contained in is typically specific to the driver, therefore the existing function v4l2_find_nearest_format() does not address the need. Signed-off-by:

If there is IR in the raw kfifo when ir_raw_event_unregister() is called, then kthread_stop() causes ir_raw_event_thread to be scheduled, decode some scancodes and re-arm timer_keyup. The timer_keyup then fires when the rc device is long gone. Cc: stable@vger.kernel.org Signed-off-by:

This patch updates the sunxi-ir driver to set the base clock frequency from devicetree. This is necessary since there are different ir receivers on the market, that operate with different frequencies. So this value could be set if the attached ir receiver needs a different base clock frequency, than the default 8 MHz. Signed-off-by:

Like in ddbridge, get rid of all duplicated I2C client handling constructs and rather make use of the newly added dvb_module_*() helpers. Makes things more clean and removes the (cosmetic) need for some variables. The check on a valid ptr on ci->en isn't really needed since the cxd2099 driver will set it at a time where it is going to return successfully from probing. Signed-off-by:

Instead of keeping duplicated I2C client handling construct, make use of the newly introduced dvb_module_*() helpers. This not only keeps things way cleaner and removes the need for duplicated I2C client attach code, but even allows to get rid of some variables that won't help in making things look cleaner anymore.
