[PATCH] clk: tegra: Fix bypassing of PLLs

Show all headers | View raw

The _clk_disable_pll() function will attempt to place a PLL into bypass
if the TEGRA_PLL_BYPASS is specified for the PLL and then disable the PLL
by clearing the enable bit. To place the PLL into bypass, the bypass bit
needs to be set and not cleared. Fix this by setting the bypass bit and
not clearing it.
