2015-11-30ASoC: rsnd: don't use normal *mod in adg.cKuninori Morimoto1-19/+11
adg.c is used from ssi/src/cmd. Thus don't use confusable *mod here. This patch rename it to ssi_mod/src_mod/cmd_mod Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-18ASoC: rsnd: remove struct platform_device from probe/remove parameterKuninori Morimoto1-4/+2
Current Renesas sound driver requests struct platform_device on probe/remove for each modules. But driver can get it by rsnd_priv_to_pdev(). This patch removes unnecessary parameter Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-18ASoC: rsnd: remove struct rsnd_of_dataKuninori Morimoto1-1/+0
No board is using Renesas sound driver via platform boot now. This means all user is using DT boot. Platform boot support is no longer needed. But, it strongly depends on platform boot style. Now, platform boot style was removed from driver. This is cleanup patch, and remove pointless struct rsnd_of_data Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-18ASoC: rsnd: remove Gen1 support from SRCKuninori Morimoto1-62/+0
This patch removes SRC Gen1 support which has no user on upstream. Historically, SRC Gen1 was created as prepare for SRC Gen2 support. It works well for Gen2 support, but Gen1 is not same as Gen2. So now, Gen1 support is no longer needed. Thanks Gen1 and Bye-bye. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-16ASoC: rsnd: call clk_prepare()/clk_enable() for AUDIO_CLKxKuninori Morimoto1-2/+19
ADG can output AUDIO_CLKOUTx, and these are generated from AUDIO_CLKx. Thus we need to call clk_prepare()/clk_enable() for AUDIO_CLKx. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-16ASoC: rsnd: Add missing initialization of ADG req_rateGeert Uytterhoeven1-1/+1
If the "clock-frequency" DT property is not found, req_rate is used uninitialized, and the "audio_clkout" clock will be created with an arbitrary clock rate. This uninitialized kernel stack data may leak to userspace through /sys/kernel/debug/clk/clk_summary, cfr. the value in the "rate" column: clock enable_cnt prepare_cnt rate accuracy phase -------------------------------------------------------------------- audio_clkout 0 0 4001836240 0 0 Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-10-22ASoC: rsnd: remove duplicate parameter from rsnd_ssi_xxx()Kuninori Morimoto1-2/+1
rsnd_ssi_use_busif() and rsnd_ssi_is_pin_sharing() are the function which returns current SSI status. But these requests duplicated parameter. This patch removes duplicated parameter. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-16ASoC: rsnd: fixup clkout_name[] index error for single AUDIO_CLKOUT SoCKuninori Morimoto1-1/+1
2a46db4a3("ASoC: rsnd: add AUDIO_CLKOUT support") added AUDIO_CLKOUT support for ADG. But single AUDIO_CLKOUT needs clkout_name[CLKOUT], not clkout_name[i]. Kernel will have NULL pointer access without this patch. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: add AUDIO_CLKOUT supportKuninori Morimoto1-4/+94
Renesas sound has AUDIO_CLKOUT (in Gen1/Gen2) AUDIO_CLKOUT1/2/3 (in Gen3) This patch support these patches as clock provider. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: adg: ignore undefined clock errorKuninori Morimoto1-9/+23
undefined clock is not error. Accept such case. And this is prepare for clock out support in the same time. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: tidyup ADG debug message for clock selectionKuninori Morimoto1-2/+3
It didn't have "\n", and indicated different data Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: tidyup ADG clock calculate methodKuninori Morimoto1-23/+54
Current ADG clock calculation needs ADG and SSI settings. Thus, SSI side clock request function depends on ADG settings. After reconsideration, we can close this method inside ADG. This function uses new method. And it becomes preparation for AUDIO_CLKOUT support. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: ADG initial setup on rsnd_adg_ssi_clk_init()Kuninori Morimoto1-8/+5
ADG is special IP since it doesn't have MSTP. And now, ADG has common mod base register access. We can now setup ADG initial setting when probe timing. It is needed if sound card is based on AUIDO_CLK which is used as Master clock. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-14ASoC: rsnd: add common mod confirm methodKuninori Morimoto1-11/+19
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). This is easy to happen in current driver style. To avoid this kind of confusable trouble, this patch adds module confirm macro for debug purpose.

2015-09-14ASoC: rsnd: ADG uses mod base common methodKuninori Morimoto1-21/+46
Renesas sound has ADG IP, but it is special device. (It is clock generater, and it doesn't need MSTP) Thus, ADG didn't use mod base common method on rsnd driver. But it can be confusable point. Let's use common method Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-01-15ASoC: rsnd: remove unsed rdai parameter from each functionKuninori Morimoto1-8/+4
Current rsnd driver's many functions requests struct rsnd_dai (= rdai), but, 1) we can get rdai from rsnd_io_to_rsnd(), 2) almost all rdai is not used. Let's remove these rdai. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Current R-Car sound driver is using device independent audio clock, but it is not good design for DT support. This patch adds device dependent clock support.

Renesas sound Gen2 has SRC (= Sampling Rate Converter) which needs 2 DMAC.

SRC clock and timing setting register exist in SRU and ADG on Gen1. But, these are merged into ADG on Gen2. Current driver is supporting Gen1 SRC only at this point, but, above settings are set as different function. This patch merges these as preparation of Gen2 support.

2013-12-31ASoC: rsnd: add SRC (Sampling Rate Converter) supportKuninori Morimoto1-0/+73
This patch adds SRC support to Renesas sound driver. SRC converts sampling rate between codec <-> cpu. It needs special codec chip, or very simple DA/AD converter to use it.
