Merge tag 'omap-for-v4.3/dt-pt4-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
Fix up bogus RTC compatible change for am4372 and add missing DPLL for am4372 cpsw Ethernet driver. Also add ARM global and local timers for am4372. * tag 'omap-for-v4.3/dt-pt4-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: arm: boot: dts: am4372: add ARM timers and SCU nodes ARM: dts: AM4372: Add the am4372-rtc compatible string ARM: dts: am4372: Set the default clock rate for dpll_clksel_mac_clk clock ARM: dts: AM437X: add dpll_clksel_mac_clk node Signed-off-by: Olof Johansson <olof@lixom.net>
