[PATCH v1] clk: Add clk_composite_set_rate_and_parent

2016-04-10 Thread Finlye Xiao
From: Finley Xiao Some of Rockchip's clocks should consider the priority of .set_parent and .set_rate to prevent a too large temporary clock rate. For example, the gpu clock can be parented to cpll(750MHz) and usbphy_480m(480MHz), 375MHz comes from cpll and the div is set to 2, 480MHz comes from
