Subject: [PATCH 8/8] clk: qcom: gcc-sm8150: Use PWRSTS_ON (only) as a workaround for emac gdsc
Date: Thu, 27 Jan 2022 03:47:25 +0530	[thread overview]
Message-ID: <20220126221725.710167-9-bhupesh.sharma@linaro.org> (raw)
In-Reply-To: <20220126221725.710167-1-bhupesh.sharma@linaro.org>

EMAC GDSC currently has issues (seen on SA8155p-ADP) when its
turn'ed ON, once its already in OFF state. So, use PWRSTS_ON
state (only) as a workaround for now.
