Subject: [PATCH RESEND 1/2] mfd: twl6040: The chip does not support bulk access
Date: Wed, 31 Aug 2016 14:46:20 +0300 [thread overview]
Message-ID: <20160831114621.6301-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20160831114621.6301-1-peter.ujfalusi@ti.com>
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.
