Merge remote-tracking branch 'agust/next' into next
From Anatolij: << There are cleanups for some mpc5121 specific drivers and DTS files in preparation to switch mpc5121 clock support to a clock driver based on common clock framework. Additionally Sebastian fixed the mpc52xx PIC driver so that it builds when using older gcc versions. >>
