[PATCH v6 02/19] clk: tegra: Change CLK_M_DIV clocks to OSC_DIV clocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Tegra has no CLK_M_DIV2 and CLK_M_DIV4 clocks from CLK_M and instead
it has OSC_DIV2 and OSC_DIV4 clocks from OSC pads.

This patch removes CLK_M_DIV2 and CLK_M_DIV4 fixed clocks and adds
OSC_DIV2 and OSC_DIV4 fixed clocks with OSC as parent for Tegra30
through Tegra210 clock drivers.
