You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From aaa84e6a0399df374634c42590e644a698fcc3ff Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 18 Apr 2017 11:43:52 +0100 Subject: [PATCH] regulator: arizona-ldo1: Move pdata into a separate structure In preparation for sharing this driver with Madera, move the pdata for the LDO1 regulator out of struct arizona_pdata into a dedicated pdata struct for this driver. As a result the code in arizona_ldo1_of_get_pdata() can be made independent of struct arizona. This patch also updates the definition of struct arizona_pdata and the use of this pdata in mach-crag6410-module.c Signed-off-by: Richard Fitzgerald Acked-by: Krzysztof Kozlowski Acked-by: Lee Jones Signed-off-by: Mark Brown --- arch/arm/mach-s3c64xx/mach-crag6410-module.c | 8 ++++-- drivers/regulator/arizona-ldo1.c | 39 +++++++++++++++------------- include/linux/mfd/arizona/pdata.h | 4 +-- include/linux/regulator/arizona-ldo1.h | 24 +++++++++++++++++ 4 files changed, 53 insertions(+), 22 deletions(-) create mode 100644 include/linux/regulator/arizona-ldo1.h diff --git a/arch/arm/mach-s3c64xx/mach-crag6410-module.c b/arch/arm/mach-s3c64xx/mach-crag6410-module.c index ccc3ab8d58e7..ea5f2169c850 100644 --- a/arch/arm/mach-s3c64xx/mach-crag6410-module.c +++ b/arch/arm/mach-s3c64xx/mach-crag6410-module.c @@ -209,7 +209,9 @@ static const struct i2c_board_info wm1277_devs[] = { };
