allow driver specific driver data in tas2781-hda-i2c and tas2781-i2c Fixes: ef3bcde75d06 ("ASoC: tas2781: Add tas2781 driver") CC: stable@vger.kernel.org Signed-off-by: Gergo Koteles <soyer@irl.hu> Link: https://lore.kernel.org/r/1398bd8bf3e935b1595a99128320e4a1913e210a.1703204848.git.soyer@irl.hu Signed-off-by: Takashi Iwai <tiwai@suse.de>
2023-12-29ALSA: hda/tas2781: do not use regcacheGergo Koteles
There are two problems with using regcache in this module. The amplifier has 3 addressing levels (BOOK, PAGE, REG). The firmware contains blocks that must be written to BOOK 0x8C. The regcache doesn't know anything about BOOK, so regcache_sync writes invalid values to the actual BOOK. The module handles 2 or more separate amplifiers. The amplifiers have different register values, and the module uses only one regmap/regcache for all the amplifiers. The regcache_sync only writes the last amplifier used. The module successfully restores all the written register values (RC profile, program, configuration, calibration) without regcache. Remove regcache functions and set regmap cache_type to REGCACHE_NONE.
