Subject: [PATCH v2 02/12] clk: tegra: don't enable PLLE HW sequencer at init
Date: Mon, 31 Aug 2020 12:40:33 +0800	[thread overview]
Message-ID: <20200831044043.1561074-3-jckuo@nvidia.com> (raw)
In-Reply-To: <20200831044043.1561074-1-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.
