2022-06-06ASoC: meson: Rename set_fmt_new back to set_fmtCharles Keepax
Now the core has been migrated across to the new direct clock specification we can move the drivers back to the normal set_fmt callback.

2022-06-06ASoC: meson: Update to use set_fmt_new callbackCharles Keepax
As part of updating the core to directly tell drivers if they are clock provider or consumer update these CPU side drivers to use the new direct callback.

2021-12-14ASoC: meson: aiu: Move AIU_I2S_MISC hold setting to aiu-fifo-i2sMartin Blumenstingl
The out-of-tree vendor driver uses the following approach to set the AIU_I2S_MISC register: 1) write AIU_MEM_I2S_START_PTR and AIU_MEM_I2S_RD_PTR 2) configure AIU_I2S_MUTE_SWAP[15:0] 3) write AIU_MEM_I2S_END_PTR 4) set AIU_I2S_MISC[2] to 1 (documented as: "put I2S interface in hold mode") 5) set AIU_I2S_MISC[4] to 1 (depending on the driver revision it always stays at 1 while for older drivers this bit is unset in step 4) 6) set AIU_I2S_MISC[2] to 0 7) write AIU_MEM_I2S_MASKS 8) toggle AIU_MEM_I2S_CONTROL[0] 9) toggle AIU_MEM_I2S_BUF_CNTL[0] Move setting the AIU_I2S_MISC[2] bit to aiu_fifo_i2s_hw_params() so it resembles the flow in the vendor kernel more closely. While here also configure AIU_I2S_MISC[4] (documented as: "force each audio data to left or right according to the bit attached with the audio data") similar to how the vendor driver does this. This fixes the infamous and long-standing "machine gun noise" issue (a buffer underrun issue).

2020-06-22ASoC: soc-component: merge snd_soc_component_read() and ↵Kuninori Morimoto
snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

2020-02-21ASoC: meson: aiu: add support for the Meson8 and Meson8b SoC familiesMartin Blumenstingl
The AIU audio controller on the Meson8 and Meson8b SoC families is compatible with the one found in the later GXBB family. Add compatible strings for these two older SoC families so the driver can be loaded for them. Instead of using the I2S divider from the AIU_CLK_CTRL_MORE register we need to use the I2S divider from the AIU_CLK_CTRL register. This older register is less flexible because it only supports four divider settings (1, 2, 4, 8) compared to the AIU_CLK_CTRL_MORE register (which supports dividers in the range 0..64).
