This could probably be removed using regmap_multi_reg_write.
The problem is that I want to retain the state of the other bits in those registers. Maybe I should make a copy of the backed up state, set the bits I want to off-device, then either:
- Write the changes with regmap_multi_reg_write
- Write all six regs again (if my device doesn't support the multi_reg)
Or make this a regmap function, there's nothing device specific about it.
I did wonder why regmap didn't have an multi-update function. If appropriate, I will add this in.
