oh... Sorry, I just got the wrong meaning
maybe it should be revised like this, right??
-------------------------------------------------------------------
#define MT6370_REG_DEV_INFO    0x100
#define MT6370_REG_CHG_IRQ1    0x1C0
#define MT6370_REG_CHG_MASK1   0x1E0
#define MT6370_REG_MAXADDR     0x1FF // Move it to here

#define MT6370_VENID_MASK      GENMASK(7, 4)

#define MT6370_NUM_IRQREGS     16
#define MT6370_USBC_I2CADDR    0x4E

#define MT6370_MAX_ADDRLEN     2    // Rename
-------------------------------------------------------------------

Thanks!
