2017-12-20ASoC: rsnd: fixup ADG register maskKuninori Morimoto1-3/+3
BRGCKR should use 0x80770000, instead of 0x80FF0000. R-Car Gen2 xxx_TIMSEL should use 0x0F1F, R-Car Gen3 xxx_TIMSEL should use 0x1F1F. Here, Gen3 doesn't support AVD, thus, both case can use 0x0F1F.

2017-10-13ASoC: rsnd: more clear ADG clock debug infoKuninori Morimoto1-18/+41
ADG inputs clock from CLK{A,B,C,I} and outputs clock from CLKOUT{0,1,2,3} which is selected by BRG{A,B}. Now, ADG is assuming BRGA is for 44100Hz related clocks, BRGB is for 48000Hz related clocks. Clock related debug is very difficult/confusable. This patch cleanups clock related debug info.

2017-08-02ASoC: rcar: unregister fixed rate on ADGKuninori Morimoto1-0/+7
ADG is registering fixed rate clock for audio_clkout, but it had not been unregister clock when removing. Salvator-X board is using ak4613 driver now, and it supports hw_constraints from commit 907cd8809eebc ("ASoC: ak4613: add hw_constraint rule for Sampling Rate"). And this calculation is using input clk. This ak4613 input clock is ADG clkout on Salvator-X. Because ADG had not been unregister clkout when unbinding, it receives fixed rate clk register error when re-binding. Thus, ak4613 can't get correct input clock, and hw_constraints will be failed after re-binding. This means Salvator-X board can't use sound after unbind/bind. This patch solves this issue.

2017-06-15ASoC: rsnd: add rsnd_adg_clk_query()Kuninori Morimoto1-26/+27
Current Renesas sound driver is assuming that all Sampling rate and channles are possible to use, but these are depends on inputed clock and SSI connection situation. For example, if it is using 1 SSI, enabled TDM mode and has 12288000 input clock, 2ch output can support until 192000Hz, but 6ch output can support until 64000Hz, 8ch can support 48000Hz. To control these situation correctly, it needs to support hw_constraints / refine feature. To support such feature, it needs SSI clock query feature, and it needs ADG clock query feature. Current ADG has rsnd_adg_ssi_clk_try_start() and it is doing similar things, but it try to setup ADG register in same time. This is not needed. This patch adds new rsnd_adg_clk_query() and separates query feature and register setting feature in adg.c Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Current clock-frequency allows only 1 clock, but ADG can handle both 44.1kHz/48kHz base clocks. This patch enables these. On Salvator-X board, AUDIO_CLKOUT which is generated by ADG is connected to ak4613 MCKI, and it should be synchronized with LRCK. Thus, we need both 44.1kHz/48kHz base clock-frequency.

2016-01-22ASoC: rsnd: each mod has status again for CTU/MUX supportKuninori Morimoto1-1/+1
SSI will be used as normal SSI or as clock parent SSI. Therefor, rsnd driver wants to control SSI and parent SSI separately. Otherwise it can't use Playback/Capture in the same time. And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod") before. OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in separately. Otherwise, these will be re-initialized during playing if MUX merges 2 sounds.

Renesas sound has SSI/SRC/DVC/MIX/ADG modules, and these have original register mapping. Thus this driver is using regmap field, and each module is using it based on each module ID. Sometimes, each module needs other module to controlling. but current each function is using just "mod" as parameter name. This is confusable. For example, if SSI0 and SRC2 are connected, and if SRC module function has bug of module access, and if it needs to control connected SSI, SRC function will access to SSI2 (It should access to SSI0, but it uses SRC's ID 2).
