Subject: [PATCH v7 02/14] clk: tegra: Don't enable PLLE HW sequencer at init
Date: Wed, 20 Jan 2021 15:34:02 +0800	[thread overview]
Message-ID: <20210120073414.69208-3-jckuo@nvidia.com> (raw)
In-Reply-To: <20210120073414.69208-1-jckuo@nvidia.com>

PLLE hardware power sequencer references PEX/SATA UPHY PLL hardware
power sequencers' output to enable/disable PLLE. PLLE hardware power
sequencer has to be enabled only after PEX/SATA UPHY PLL's sequencers
are enabled.
