[alsa-devel] [PATCH 0/5] ASoC/MFD: twl6040: Remove codec driver local reg cache
by Peter Ujfalusi 19 Dec '13

19 Dec '13

Hi Mark, It was not straight forward task to remove the local reg cache from the twl6040 codec driver. I also needed to change the MFD part so it will take over the caching of registers via regmap. So far I have the following patches working on top of mainline kernel. Is this close enough of what you had in mind when asked me to look at this? twl4030 codec is going to be a bit more complicated AFAIK but it will come eventually. Regards, Peter --- Peter Ujfalusi (5): ASoC: twl6040: Rename twl6040_is_path_unmuted -> twl6040_can_write_to_chip ASoC: twl6040: Custom caching for sensitive DL1/2 path registers MFD: twl6040: reg_defaults support for regmap ASoC: twl6040: Remove register restore functionality ASoC: twl6040: Remove self managed local reg_cache support drivers/mfd/twl6040.c | 92 +++++++++++++++++- sound/soc/codecs/twl6040.c | 227 +++++++++++++-------------------------------- 2 files changed, 155 insertions(+), 164 deletions(-) -- 1.8.4.2

[alsa-devel] [PATCH] ALSA: hda - Add warning texts when codec driver Kconfig doesn't match
by Takashi Iwai 19 Dec '13

19 Dec '13

When a Kconfig of a codec driver doesn't match with the controller (CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic probing. Unfortunately kbuild can't give such a restriction, but at least, it's possible to show a warning if such a condition is found.

[alsa-devel] [PATCH V2 1/2] ASoC: SPEAr: get rid of spear-pcm-audio struct device
by Stephen Warren 18 Dec '13

18 Dec '13

From: Stephen Warren <swarren(a)nvidia.com> Modify the SPEAr PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device. This is also required as a pre-cursor to removing spear_pcm_request_chan().
