Subject: [PATCH v2 1/3] mfd: documentation: dt: Document grounded ACOKB pin on S2MPS11
Date: Tue, 11 Aug 2015 19:09:04 +0900	[thread overview]
Message-ID: <1439287746-14034-2-git-send-email-k.kozlowski.k@gmail.com> (raw)
In-Reply-To: <1439287746-14034-1-git-send-email-k.kozlowski.k@gmail.com>

Document a new Device Tree property 'samsung,s2mps11-acokb-ground'
indicating that ACOKB pin of S2MPS11 PMIC is connected to the ground so
the PMIC must manually set PWRHOLD bit in CTRL1 register to turn off the
power.
