Hi Chen, what I would ask you is to be consistent with the naming, if your driver is called mtk-pmic, then all your functions and global variables should be named accordingly as mtk_pmic or MTK_PMIC. Please check in between the lines for real examples: > +#define PWRKEY_RST_EN_MASK 0x1 > +#define PWRKEY_RST_EN_SHIFT 6 > +#define HOMEKEY_RST_EN_MASK 0x1 > +#define HOMEKEY_RST_EN_SHIFT 5 > +#define RST_DU_MASK 0x3 > +#define RST_DU_SHIFT 8 > + > +#define PMIC_PWRKEY_INDEX 0 > +#define PMIC_HOMEKEY_INDEX 1 > +#define PMIC_MAX_KEY_COUNT 2 #define MTK_PMIC_* > +struct pmic_keys_regs { struct mtk_pmic_keys_regs > + u32 deb_reg; > + u32 deb_mask; > + u32 intsel_reg; > + u32 intsel_mask; > +}; > + > +#define PMIC_KEYS_REGS(_deb_reg, _deb_mask, _intsel_reg, _intsel_mask) \ MTK_PMIC_KEYS_REGS > +{ \ > + .deb_reg = _deb_reg, \ > + .deb_mask = _deb_mask, \ > + .intsel_reg = _intsel_reg, \ > + .intsel_mask = _intsel_mask, \ > +} > + > +struct pmic_regs { mtk_pmic_regs and so on... you got the point.
