commit ac5468b57d49fa86efc606ab06f98a6e532d5de1 Author: David Hendricks dhendrix@chromium.org Date: Mon Aug 12 14:52:45 2013 -0700
exynos5420: Assign corect parent PLLs
Assign correct parent PLL's for the following clocks: ACLK_400_WCORE (MPLL->CPLL) (400 -> 333MHz) PCLK_200_FSYS (MPLL->DPLL) (200 -> 200MHz) MUX_ACLK_100_NOC_SEL (MPLL -> DPLL) (100 -> 100MHz) ACLK_266 (DPLL->MPLL) (300 -> 266MHz) ACLK_200_DISP1(MPLL->DPLL) (200 -> 200MHz) ACLK_400_MSCL(MPLL->CPLL) (400 -> 333MHz) ACLK_66 (MPLL->CPLL) (66.666 -> 66.6MHz) MUX_ACLK_400_DISP1_SEL (CPLL->DPLL) (666 -> 300MHz) MUX_MPHY_REFCLK (MPLL->OSC) MUX_UNIPRO (MPLL->OSC) MUX_MIPI1 (EPLL->OSC) MUX_DP1_EXT_VID (EPLL->OSC) MUX_FIMD1_OPT (EPLL->OSC) MUX_IPLL(IPLL->OSC) This also corrects the clock dividers for few of the clocks, as the clock parent changes affect the final frequency of the clocks.
