* ASoC: rsnd: add rsnd_scu_transfer_start()Kuninori Morimoto2013-12-31
| | | | | | | | | | | | | | | | | Renesas sound has SRC (= Sampling Rate Converter), but, the HW implementation depends on its generation. It was part of SRU on Gen1, and SCU on Gen2. This SCU needs DMA transfer to use it. Current rsnd driver is using it as DMA transfer buffer (= no rate convert), and Gen1 is only supported at this point. This patch cleanup it with focusing about SRC and Gen2 part. SRC_CTRL/BUSIF_MODE are used for transfer start. This patch adds rsnd_scu_transfer_start() and merge these Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

This patch cleanup it with focusing about SRC and Gen2 part. rsnd_scu_set_route() is needed only Gen1. This patch renames it to rsnd_scu_set_route_if_gen1() and it adds comment to rsnd_reg member in order to clarify it is used for Gen1.

* ASoC: rsnd: make sure variable name for 44.1kHz/48kHzKuninori Morimoto2013-12-31
| | | | | | | | | | This driver is assuming that RBGA is used as source clock of 44.1kHz category, and RBGB is used as source clock of 48kHz category. This patch clarifies the variable name.

| | | | | | | | | This patch adds rsnd_adg_set_ssi_clk() to access to AUDIO_CLK_SEL0/1/2, and removes last user of rsnd_write/read/bset which is very low level function. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

* ASoC: rcar: add Gen2 sound supportKuninori Morimoto2013-11-29
| | | | | | | | This patch adds Gen2 sound support for Renesas R-Car. But, it is supporting PIO transfer only at this point Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: rcar: remove rcar_gen_opsKuninori Morimoto2013-11-29
| | | | | | | | | | | Current rcar driver gen.c is using rcar_gen_ops which was made with the assumption that Gen1 and Gen2 need different behavior. but it was not needed. This patch removes unnecessary complex method. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: rcar: remove .path_init/exit from rsnd_gen_opsKuninori Morimoto2013-11-29
| | | | | | | | | | | | rsnd_gen_ops has .path_init/exit callback function which cares SRU/SSI (if Gen1) SCU/SSIU/SSI (if Gen2) path settings. But, the differences between Gen1/Gen2 are cared in ssi.c/scu.c, and the path itself is same in Gen1/Gen2. This patch removes .path_init/exit callback.

* ASoC: rcar: add rsnd_is_accessible_reg()Kuninori Morimoto2013-11-29
| | | | | | | | | | | | Current rcar driver is supporting Gen1, and Gen2 will be supported soon. Then, some registers are used from Gen1 only, or from Gen2 only. To avoid NULL pointer access, this patch adds register accessible check function. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: rcar: separate regmap init common fieldKuninori Morimoto2013-11-29
| | | | | | | | | | The repmap initialization difference between Gen1/Gen2 is only register offset. This patch separates rsnd_gen1_regmap_init() into common part and Gen1 specific part.

Although the device supports paging this is not currently implemented as the additional pages are only used during the application of the patch for the TLV320AIC3007.

The datasheet and the driver document the device as having a register map divided into pages but since the paging is actually done by sending the page address and the register address with each transaction this is no different to having a simple register address. The datasheet does also document the low five bits of the 16 bit "command" as unused which we could represent as padding but it seems simpler and less confusing to things that use block transfers or autoincrement to represent these as part of the register address.
