From c78cb17867e48a4b74abbc8ffc52ac1ed5d0299d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 31 Aug 2016 14:46:20 +0300 Subject: [PATCH] mfd: twl6040: The chip does not support bulk access Bulk access is not working with twl6040, we need to use single register access. Bulk access would happen when we try to sync the regcache after power on.
