MPE, VI, EPP and ISP were never used and we don't have drivers for them. Since these modules are enabled by default in a device-tree, a device is created for them, blocking voltage scaling because there is no driver to bind, and thus, state of PMC driver is never synced. Disable them. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> --- arch/arm/boot/dts/tegra20.dtsi | 4 ++++ arch/arm/boot/dts/tegra30.dtsi | 8 ++++++++ 2 files changed, 12 insertions(+)
