Subject: [PATCH 1/2] mfd: wm5110: Expose DRE control registers
Date: Thu, 19 Dec 2013 09:11:01 +0000 [thread overview]
Message-ID: <1387444262-26456-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
Certain use-cases require the DRE to be disabled so expose registers
necessary to control the DRE enables.
