[PATCH v4 1/7] clk: tegra30: Use 300MHz for video decoder by default
From: Dmitry Osipenko <digetx@gmail.com>
Date: 2021-03-12 16:38:25
Also in:
linux-clk, linux-tegra, lkml
Subsystem:
common clk framework, tegra clock driver, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Prashant Gaikwad, Linus Torvalds
The 600MHz is a too high clock rate for some SoC versions for the video
decoder hardware and this may cause stability issues. Use 300MHz for the
video decoder by default, which is supported by all hardware versions.
