Subject: [PATCH v1 1/2] clk: tegra: Mark HCLK, SCLK, EMC, MC and PLL_P outputs as critical
Machine dies if HCLK, SCLK or EMC is disabled, hence mark these clocks
as critical. Currently some of drivers do not manage clocks properly,
expecting those clocks to be 'always enabled', these clocks are MC and
PLL_P outputs. Let's mark MC or PLL_P outputs as critical for now and
revert this change once drivers would be corrected.
