Subject: [BACKPORT 4.14.y 05/18] mfd: palmas: Assign the right powerhold mask for tps65917
Date: Thu, 5 Sep 2019 10:17:46 -0600 [thread overview]
Message-ID: <20190905161759.28036-6-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190905161759.28036-1-mathieu.poirier@linaro.org>
From: Keerthy <j-keerthy@ti.com>
commit 572ff4d560be3784205b224cd67d6715620092d7 upstream
The powerhold mask for TPS65917 is different when comapred to
the other palmas versions. Hence assign the right mask that enables
power off of tps65917 pmic correctly.
