From 55562449032c43b84f839e2fbb84bf1d351d6603 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 15 Sep 2016 13:56:11 -0700 Subject: [PATCH] regmap: Add missing little endian functions This with the longer read and write masks allow supporting more exotic devices. For example a little endian SPI device: static const struct regmap_config foo_regmap_config = { .reg_bits = 16, .reg_stride = 4, .val_bits = 16, .write_flag_mask = 0x8000, .reg_format_endian = REGMAP_ENDIAN_LITTLE, .val_format_endian = REGMAP_ENDIAN_LITTLE, ... }; Signed-off-by: Tony Lindgren Signed-off-by: Mark Brown --- drivers/base/regmap/regmap.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/drivers/base/regmap/regmap.c b/drivers/base/regmap/regmap.c index a6a5236b6c8d..31cfe70e6d53 100644 --- a/drivers/base/regmap/regmap.c +++ b/drivers/base/regmap/regmap.c @@ -749,6 +749,9 @@ struct regmap *__regmap_init(struct device *dev, case REGMAP_ENDIAN_BIG: map->format.format_reg = regmap_format_16_be; break; + case REGMAP_ENDIAN_LITTLE: + map->format.format_reg = regmap_format_16_le; + break; case REGMAP_ENDIAN_NATIVE: map->format.format_reg = regmap_format_16_native; break; @@ -768,6 +771,9 @@ struct regmap *__regmap_init(struct device *dev, case REGMAP_ENDIAN_BIG: map->format.format_reg = regmap_format_32_be; break; + case REGMAP_ENDIAN_LITTLE: + map->format.format_reg = regmap_format_32_le; + break; case REGMAP_ENDIAN_NATIVE: map->format.format_reg = regmap_format_32_native; break; @@ -782,6 +788,9 @@ struct regmap *__regmap_init(struct device *dev, case REGMAP_ENDIAN_BIG: map->format.format_reg = regmap_format_64_be; break; + case REGMAP_ENDIAN_LITTLE: + map->format.format_reg = regmap_format_64_le; + break; case REGMAP_ENDIAN_NATIVE: map->format.format_reg = regmap_format_64_native; break;
