2021-05-27ASoC: rsnd: add debugfs supportKuninori Morimoto1-0/+9
Current rsnd supports #define DEBUG, but it is not helpful if issue happen after 4-5 hours. This patch adds debugfs support for it.

2020-05-12SoC: rsnd: add interrupt support for SSI BUSIF bufferYongbo Zhang1-0/+8
SSI BUSIF buffer is possible to overflow or underflow, especially in a hypervisor environment. If there is no interrupt support, it will eventually lead to errors in pcm data. This patch adds overflow and underflow interrupt support for SSI BUSIF buffer.

2019-02-26ASoC: rsnd: gen: fix SSI9 4/5/6/7 busif related register addressJiada Wang1-0/+24
Currently each SSI unit 's busif mode/adinr/dalign address is registered by: (in busif4 case) RSND_GEN_M_REG(SSI_BUSIF4_MODE, 0x500, 0x80) RSND_GEN_M_REG(SSI_BUSIF4_ADINR,0x504, 0x80) RSND_GEN_M_REG(SSI_BUSIF4_DALIGN, 0x508, 0x80) But according to user manual 41.1.4 Register Configuration ssi9 4/5/6/7 busif mode/adinr/dalign register address ( SSI9-[4/5/6/7]_BUSIF_[MODE/ADINR/DALIGN] ) are out of this rule. This patch registers ssi9 4/5/6/7 mode/adinr/dalign register as single register, and access these registers in case of SSI9 BUSIF 4/5/6/7.

2018-12-12ASoC: rsnd: remove RSND_REG_ from rsnd_regKuninori Morimoto1-11/+12
Current rsnd is using RSND_REG_xxx for register naming, and using RSND_REG_##f style macro for read/write. The biggest reason why it uses this style is that we can avoid non-existing register access. But, its demerit is sequential register access code will be very ugly. Current rsnd driver is well tested, so, let's remove RSND_REG_ from rsnd_reg, and cleanup sequential register access code.

2018-12-04ASoC: rsnd: fixup mod ID for CTU regmap read/writeKuninori Morimoto1-3/+11
commit c16015f36cc12824 ("ASoC: rsnd: add .get_id/.get_id_sub") add new .get_id/.get_id_sub to indicate module ID/subID. It is used for SSIU and CTU. In SSIU case, subID indicates BUSIF, but register settings is based on SSIU ID. OTOH, in CTU case, subID indicates CTU channel, and register settings is based on it. This means regmap read/write function needs to care it. This patch fixup this issue. It can't play MIXed sound without this patch.

2018-11-05ASoC: rsnd: rsnd_mod_name() handles both name and IDKuninori Morimoto1-6/+6
Current rsnd driver is using "%s[%d]" for mod name and ID, but, this ID portion might confusable. For example currently, CTU ID is 0 to 7, but using 00 to 13 (= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet. In the future, we will support BUSIFn, but it will be more complicated numbering. To avoid future confusable code, this patch modify rsnd_mod_name() to return understandable name. To avoid using pointless memory, it uses static char and snprintf, thus, rsnd_mod_name() user should use it immediately, and shouldn't keep its pointer.

One note is that we can't support SSI9-4/5/6/7 so far, because its address is out of calculation rule.

rsnd driver is supporting Gen3. The difference between Gen1 and Gen2 were very big, but, between Gen2 and Gen3 are not so much. Thus, it is assuming Gen2 and Gen3 have compatible, therefore, there is no RSND_GEN3 and rsnd_is_gen3() macro. But in the future, it will need Gen2 and Gen3 different operation, and for Gen4.
