Subject: [PATCH AUTOSEL 4.9 046/251] clk: sunxi-ng: sun8i-a23: Enable PLL-MIPI LDOs when ungating it
Date: Thu, 16 Jan 2020 12:33:15 -0500
Message-ID: <20200116173641.22137-6-sashal@kernel.org> (raw)
In-Reply-To: <20200116173641.22137-1-sashal@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

[ Upstream commit 108a459ef4cd17a28711d81092044e597b5c7618 ]

The PLL-MIPI clock is somewhat special as it has its own LDOs which
need to be turned on for this PLL to actually work and output a clock
signal.

Add the 2 LDO enable bits to the gate bits.
