mfd: max77620: Use single-byte writes on MAX77620
Browse files Browse the repository at this point in the history
The MAX77620 doesn't support bulk writes, so make sure the regmap code
breaks bulk writes into multiple single-byte writes.

Note that this is mostly cosmetic because currently only the RTC sub-
driver uses bulk writes and the RTC driver ends up using a different
regmap on the MAX77620 anyway. However, it seems like a good idea to
make this change now in order to avoid running into issues if bulk
writes are ever used by other sub-drivers sometime down the road.
