From: Peng Fan <[email protected]> pll BYPASS bit should be kept inside pll driver for glitchless freq setting following spec. If exposing the bit, that means pll driver and clk driver has two paths to touch this bit, which is wrong.
So use EXT_BYPASS bit here. And drop uneeded set parent, because EXT_BYPASS default is 0.
