Subject: [PATCH 2/8] clk: tegra: don't enable PLLE HW sequencer at init
Date: Fri, 14 Jun 2019 15:46:50 +0800 [thread overview]
Message-ID: <20190614074652.21960-3-jckuo@nvidia.com> (raw)
In-Reply-To: <20190614074652.21960-1-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.
