Subject: ARM: DRA7xx: clocks: Update PLL values
X-Git-Tag: v2013.07-rc1~2^2~3^2~8
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=97405d843ece2a53e67b801e02ee42005d26e172;p=oweals%2Fu-boot.git

ARM: DRA7xx: clocks: Update PLL values

Update PLL values.
SYS_CLKSEL value for 20MHz is changed to 2. In other platforms
SYS_CLKSEL value 2 represents reserved. But in sys_clk array
ind 1 is used for 13Mhz. Since other platforms are not using
13Mhz, reusing index 1 for 20MHz.
