* | ASoC: sunxi: make snd_soc_codec_driver structures as constBhumika Goyal2017-08-072-4/+4
| | | | | | | | | | | | | | | | | | | | | | Declare snd_soc_codec_driver structures as const as they are either passed as an argument to the function snd_soc_register_codec or stored as reference in field codec of type sun4i_codec_quirks. Both the fucntion argument and the codec field are of type const, so declare the structures with this property as const.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

On a second play (right after), the sound is played correctly. If we wait a short time (~5 sec which corresponds to the aplay timeout), the delay is back. This patch fixes it by using an event on headphone amplifier. It allows to keep the amplifier enable while playing a sound. A delay of 700ms allows to wait that the amplifier is powered-up before playing the sound.

* ASoC: sun4i-codec: Increase DMA max burst to 8Chen-Yu Tsai2016-11-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the DMA engine API documentation, maxburst denotes the largest possible size of a single transfer, so as not to overflow destination FIFOs as explained in this excerpt from dmaengine.h * @src_maxburst: the maximum number of words (note: words, as in * units of the src_addr_width member, not bytes) that can be sent * in one burst to the device. Typically something like half the * FIFO depth on I/O peripherals so you don't overflow it. This * may or may not be applicable on memory sources. * @dst_maxburst: same as src_maxburst but for destination target * mutatis mutandis. The TX FIFO is 64 samples deep for stereo, and the RX FIFO is 16 samples deep. So maxburst could be 32 and 8 for TX and RX respectively. Unfortunately the sunxi DMA controller driver takes maxburst as the requested burst size, rather than a limit, and returns an error for unsupported values. The original value was 4, but some later SoCs do not officially support this burst size. This patch increases maxburst on the TX side to 8, which is supported by all variants of the sunxi DMA controller.

* ASoC: sun4i-codec: Expand quirks to handle register offsets and card creationChen-Yu Tsai2016-11-031-27/+60
| | | | | | | | | | | | | | | | | | | | | The A31 has a similar codec to the A10/A20. The PCM parts are very similar, with just different register offsets. The analog paths are very different. There are more inputs and outputs. The A31s, A23, and H3 have a similar PCM interface, again with register offsets slightly rearranged. The analog path controls, while very similar between them and the A31, have been moved a separate bus which is accessed through a message box like interface in the PRCM address range. This would be handled by a separate auxiliary device tied in through the device tree in its supporting create_card function. The quirks structure is expanded to include different register offsets and separate callbacks for creating the ASoC card. The regmap_config, quirks, and of_device_match tables have been moved to facilitate this.

| * ASoC: sun4i-codec: Enable bus clock after getting GPIOChen-Yu Tsai2016-11-011-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current probe function the GPIO is acquired after the codec's bus clock is enabled. However if it fails to acquire the GPIO due to a deferred probe, it does not disable the bus clock before bailing out. This would result in the clock being enabled multiple times. Move the code that enables the bus clock after the part that gets the GPIO, maintaining a separation between resource acquisition and device enablement in the probe function.

| | | | | | | | | | | | | | | | | | | | This revises existing comments in the register definition macros section, and adds a few more, so that readers can clearly identify the types of control registers.

* | ASoC: sun4i-codec: Move data structures to add create_card call to quirksChen-Yu Tsai2016-11-031-39/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audio codec on later Allwinner SoCs have a different layout and audio path compared to the A10/A20. However the PCM parts are still the same. The different layout and audio paths mean we need a different create_card function for different families, so they can create DAPM endpoint widgets and routes. This patch moves the regmap configs, quirks and of_device_id structures to just before the probe function, so we can, among other things, include a pointer for the create_card function. None of the lines of code were changed. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: sun4i-codec: return error code instead of NULL when create_card failsChen-Yu Tsai2016-10-311-3/+4
| | | | | | | | | | | | | | | | When sun4i_codec_create_card fails, we do not assign a proper error code to the return value. The return value would be 0 from the previous function call, or we would have bailed out sooner. This would confuse the driver core into thinking the device probe succeeded, when in fact it didn't, leaving various devres based resources lingering. Make the create_card function pass back a meaningful error code, and assign it to the return value.
