From b150a703b56fb6eb282d059b421652ccd9155c23 Mon Sep 17 00:00:00 2001 From: Hermes Zhang Date: Fri, 8 Dec 2023 11:47:08 +0800 Subject: [PATCH] power: supply: bq24190_charger: Add support for BQ24296 The BQ24296 is most similar to the BQ24196, but the: 1. OTG config is split from CHG config (REG01) 2. ICHG (Fast Charge Current limit) range is smaller (<=3008mA) 3. NTC fault is simplified to 2 bits Signed-off-by: Hermes Zhang Link: https://lore.kernel.org/r/20231208034708.1248389-3-Hermes.Zhang@axis.com Signed-off-by: Sebastian Reichel --- drivers/power/supply/bq24190_charger.c | 459 +++++++++++++++++++------ 1 file changed, 355 insertions(+), 104 deletions(-) diff --git a/drivers/power/supply/bq24190_charger.c b/drivers/power/supply/bq24190_charger.c index 1db290ee2591..a8995a21fadb 100644 --- a/drivers/power/supply/bq24190_charger.c +++ b/drivers/power/supply/bq24190_charger.c @@ -36,10 +36,16 @@ #define BQ24190_REG_POC_WDT_RESET_SHIFT 6 #define BQ24190_REG_POC_CHG_CONFIG_MASK (BIT(5) | BIT(4)) #define BQ24190_REG_POC_CHG_CONFIG_SHIFT 4 -#define BQ24190_REG_POC_CHG_CONFIG_DISABLE 0x0 -#define BQ24190_REG_POC_CHG_CONFIG_CHARGE 0x1 -#define BQ24190_REG_POC_CHG_CONFIG_OTG 0x2 -#define BQ24190_REG_POC_CHG_CONFIG_OTG_ALT 0x3 +#define BQ24190_REG_POC_CHG_CONFIG_DISABLE 0x0 +#define BQ24190_REG_POC_CHG_CONFIG_CHARGE 0x1 +#define BQ24190_REG_POC_CHG_CONFIG_OTG 0x2 +#define BQ24190_REG_POC_CHG_CONFIG_OTG_ALT 0x3 +#define BQ24296_REG_POC_OTG_CONFIG_MASK BIT(5) +#define BQ24296_REG_POC_OTG_CONFIG_SHIFT 5 +#define BQ24296_REG_POC_CHG_CONFIG_MASK BIT(4) +#define BQ24296_REG_POC_CHG_CONFIG_SHIFT 4 +#define BQ24296_REG_POC_OTG_CONFIG_DISABLE 0x0 +#define BQ24296_REG_POC_OTG_CONFIG_OTG 0x1 #define BQ24190_REG_POC_SYS_MIN_MASK (BIT(3) | BIT(2) | BIT(1)) #define BQ24190_REG_POC_SYS_MIN_SHIFT 1 #define BQ24190_REG_POC_SYS_MIN_MIN 3000 @@ -134,18 +140,76 @@ #define BQ24190_REG_F_BAT_FAULT_SHIFT 3 #define BQ24190_REG_F_NTC_FAULT_MASK (BIT(2) | BIT(1) | BIT(0)) #define BQ24190_REG_F_NTC_FAULT_SHIFT 0 +#define BQ24296_REG_F_NTC_FAULT_MASK (BIT(1) | BIT(0)) +#define BQ24296_REG_F_NTC_FAULT_SHIFT 0 #define BQ24190_REG_VPRS 0x0A /* Vendor/Part/Revision Status */ #define BQ24190_REG_VPRS_PN_MASK (BIT(5) | BIT(4) | BIT(3)) #define BQ24190_REG_VPRS_PN_SHIFT 3 -#define BQ24190_REG_VPRS_PN_24190 0x4 -#define BQ24190_REG_VPRS_PN_24192 0x5 /* Also 24193, 24196 */ -#define BQ24190_REG_VPRS_PN_24192I 0x3 +#define BQ24190_REG_VPRS_PN_24190 0x4 +#define BQ24190_REG_VPRS_PN_24192 0x5 /* Also 24193, 24196 */ +#define BQ24190_REG_VPRS_PN_24192I 0x3 +#define BQ24296_REG_VPRS_PN_MASK (BIT(7) | BIT(6) | BIT(5)) +#define BQ24296_REG_VPRS_PN_SHIFT 5 +#define BQ24296_REG_VPRS_PN_24296 0x1 #define BQ24190_REG_VPRS_TS_PROFILE_MASK BIT(2) #define BQ24190_REG_VPRS_TS_PROFILE_SHIFT 2 #define BQ24190_REG_VPRS_DEV_REG_MASK (BIT(1) | BIT(0)) #define BQ24190_REG_VPRS_DEV_REG_SHIFT 0 +/* + * The tables below provide a 2-way mapping for the value that goes in + * the register field and the real-world value that it represents. + * The index of the array is the value that goes in the register;
