From 12e5bf757a1fd03c5d736942428732be641daa1c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 17 Apr 2020 19:09:13 +0200 Subject: mfd: max77620: Use single-byte writes on MAX77620 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.
