| | * ASoC: sun4i-i2s: Add support for A83TChen-Yu Tsai2017-12-12
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2S controller in the A83T is mostly compatible with the one found in earlier SoCs such as the A20 and A31. While the documents publicly available for the A83T do not cover this hardware, the officially released BSP kernel does have register definitions for it. These were matched against the A20 user manual. The only difference is the TX FIFO and interrupt status registers have been swapped around, like what we have seen with the SPDIF controller. This patch adds support for this hardware. 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-i2s: Show detailed error when DAI configuration callbacks failChen-Yu Tsai2017-12-14
|/ | | | | | | | | | | | | | | | | | | When any of the DAI hardware configuration callbacks (.hw_param, .set_fmt, .set_sysclk) fails, there is no explanation about why it failed. This is particularly confusing for .hw_param, which covers many parameters of the DAI. Telling the users what parameter isn't supported, and what the requested value was goes a long way for developers trying to combine sun4i-i2s with external codecs. This patch adds dev_err calls explaining what isn't supported or failed, and what the value was. sun4i_i2s_set_clk_rate()'s first parameter was changed to a struct snd_soc_dai *dai, so we can get the underlying device.

* ASoC: sun4i-i2s: Add support for H3Marcus Cooper2017-08-21
| | | | | | | | | | | | | | The sun8i-h3 introduces a lot of changes to the i2s block such as different register locations, extended clock division and more operational modes. As we have to consider the earlier implementation then these changes need to be isolated. None of the new functionality has been implemented yet, the driver has just been expanded to allow it work on the H3 SoC.

| | | | | | | | | | | | | | | | | | 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | Some SoCs have a reset line that must be asserted/deasserted. This patch adds a quirk to handle the new compatible "allwinner,sun6i-a31-i2s" which will deassert the reset line on probe function and assert it on remove's one.

* ASoC: sunxi: i2s: Implement set_sysclkMaxime Ripard2016-11-09
| | | | | | | | | | | | | | | In our i2s driver, we were previously trying to guess which oversample the user wanted to use by looking at the rate and trying to max it. However, the cards, and especially simple-card with its mclk-fs property will already provide the expected oversample ratio by using the set_sysclk callback. We can thus implement it and remove the logic to deal with the runtime guess. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@kernel.org>
