From: Vadim Pasternak Date: Wed, 14 Dec 2016 12:05:15 +0000 (+0000) Subject: platform/x86: mlx-platform: mlxcpld-hotplug driver style fixes X-Git-Tag: v4.11-rc1~70^2~41 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a38b67c9877a7371a250454bbbbf521d02fded5;p=karo-tx-linux.git platform/x86: mlx-platform: mlxcpld-hotplug driver style fixes The patch contains several styling fixes: - Make names of hotplug devices shorter; - Change register offset assignment to defines; - Add defines for the all event masks; - Use PLATFORM_DEVID_NONE instead of -1; Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko --- diff --git a/drivers/platform/x86/mlx-platform.c b/drivers/platform/x86/mlx-platform.c index 25f15df5c2d7..8f98c211b440 100644 --- a/drivers/platform/x86/mlx-platform.c +++ b/drivers/platform/x86/mlx-platform.c @@ -45,6 +45,10 @@ /* LPC bus IO offsets */ #define MLXPLAT_CPLD_LPC_I2C_BASE_ADRR 0x2000 #define MLXPLAT_CPLD_LPC_REG_BASE_ADRR 0x2500 +#define MLXPLAT_CPLD_LPC_REG_AGGR_ADRR 0x253a +#define MLXPLAT_CPLD_LPC_REG_PSU_ADRR 0x2558 +#define MLXPLAT_CPLD_LPC_REG_PWR_ADRR 0x2564 +#define MLXPLAT_CPLD_LPC_REG_FAN_ADRR 0x2588 #define MLXPLAT_CPLD_LPC_IO_RANGE 0x100 #define MLXPLAT_CPLD_LPC_I2C_CH1_OFF 0xdb #define MLXPLAT_CPLD_LPC_I2C_CH2_OFF 0xda @@ -56,6 +60,17 @@ MLXPLAT_CPLD_LPC_I2C_CH2_OFF) | \ MLXPLAT_CPLD_LPC_PIO_OFFSET) +/* Masks for aggregation, psu, pwr and fan event in CPLD related registers. */ +#define MLXPLAT_CPLD_AGGR_PSU_MASK_DEF 0x08 +#define MLXPLAT_CPLD_AGGR_PWR_MASK_DEF 0x08 +#define MLXPLAT_CPLD_AGGR_FAN_MASK_DEF 0x40 +#define MLXPLAT_CPLD_AGGR_MASK_DEF (MLXPLAT_CPLD_AGGR_PSU_MASK_DEF | \ + MLXPLAT_CPLD_AGGR_FAN_MASK_DEF) +#define MLXPLAT_CPLD_AGGR_MASK_MSN21XX 0x04 +#define MLXPLAT_CPLD_PSU_MASK GENMASK(1, 0) +#define MLXPLAT_CPLD_PWR_MASK GENMASK(1, 0) +#define MLXPLAT_CPLD_FAN_MASK GENMASK(3, 0) + /* Start channel numbers */ #define MLXPLAT_CPLD_CH1 2 #define MLXPLAT_CPLD_CH2 10 @@ -123,7 +138,7 @@ static struct i2c_mux_reg_platform_data mlxplat_mux_data[] = { };
