From 2e9688c81cfc48b210af6f313cb04589b7943e86 Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Tue, 11 Apr 2023 00:39:01 +0200 Subject: [PATCH] ASoC: cs4271: flat regcache, trivial simplifications - Switch to REGCACHE_FLAT, the whole overhead of RBTREE is not worth it with non sparse register set in the address range 1..7. - Move register width to central location Signed-off-by: Alexander Sverdlin Link: https://lore.kernel.org/r/20230410223902.2321834-3-alexander.sverdlin@gmail.com Signed-off-by: Mark Brown --- sound/soc/codecs/cs4271-i2c.c | 1 - sound/soc/codecs/cs4271-spi.c | 1 - sound/soc/codecs/cs4271.c | 4 ++-- 3 files changed, 2 insertions(+), 4 deletions(-) diff --git a/sound/soc/codecs/cs4271-i2c.c b/sound/soc/codecs/cs4271-i2c.c index 0e8a7cf0da505..4033be1c3bc1b 100644 --- a/sound/soc/codecs/cs4271-i2c.c +++ b/sound/soc/codecs/cs4271-i2c.c @@ -17,7 +17,6 @@ static int cs4271_i2c_probe(struct i2c_client *client) config = cs4271_regmap_config; config.reg_bits = 8; - config.val_bits = 8; return cs4271_probe(&client->dev, devm_regmap_init_i2c(client, &config)); diff --git a/sound/soc/codecs/cs4271-spi.c b/sound/soc/codecs/cs4271-spi.c index 7ef0a66b77789..4feb80436bd99 100644 --- a/sound/soc/codecs/cs4271-spi.c +++ b/sound/soc/codecs/cs4271-spi.c @@ -17,7 +17,6 @@ static int cs4271_spi_probe(struct spi_device *spi) config = cs4271_regmap_config; config.reg_bits = 16; - config.val_bits = 8; config.read_flag_mask = 0x21; config.write_flag_mask = 0x20; diff --git a/sound/soc/codecs/cs4271.c b/sound/soc/codecs/cs4271.c index 2021cf4426061..188b8b43c524f 100644 --- a/sound/soc/codecs/cs4271.c +++ b/sound/soc/codecs/cs4271.c @@ -689,8 +689,8 @@ const struct regmap_config cs4271_regmap_config = { .reg_defaults = cs4271_reg_defaults, .num_reg_defaults = ARRAY_SIZE(cs4271_reg_defaults), - .cache_type = REGCACHE_RBTREE, - + .cache_type = REGCACHE_FLAT, + .val_bits = 8, .volatile_reg = cs4271_volatile_reg, }; EXPORT_SYMBOL_GPL(cs4271_regmap_config); -- 2.30.2
