From: Stuart Menefy <stuart.menefy@xxxxxxxxxxxxxxxx> By default the MMC clock will be derived from mediatop PLL, which usually runs at 666MHz. However as most SD and MMC clocks are multiples or fractions of 100MHz, it makes more sense to use the bustop PLL which runs at 800MHz. This matches the behaviour of the Samsung vendor supplied 3.4 kernel.
