Can we use regmap_range and regmap_access_table?
Can the regmap_range support discontinuous registers? The reg_stride = 4.
I think it does. Giving an example here: https://github.com/torvalds/linux/blob/master/drivers/mfd/da9063-i2c.c
The register in this i2c driver are continuous, from 0x00, 0x01, 0x02...
But our case is 0x00, 0x04, 0x08, does it work?
Ah...I see your point now. I am not very sure -- have only used in I2C drivers. You can ignore if it doesn't likely work for us.
