Merge tag 'integrator-armsoc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/late
Pull "This is a bunch of Integrator changes for v4.9" Linus Walleij: - Add and fix a bunch of clocks in the DTS corresponding to the new clock support merged into the clk tree. - Move the CLCD display configuration from boardfile to device tree using the new CLCD support merged into the fbdev tree. - Cut some auxdata. - Cut some static remappings. - Move the sched_clock() counter to use syscon+regmap. * tag 'integrator-armsoc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: integrator: read counter using syscon/regmap ARM: integrator: cut down on static maps ARM: integrator: delete some auxdata ARM: integrator: move CP CLCD display to DTS ARM: dts: add the core module clocks to Integrator/CP ARM: dts: Add the core module clocks to Integrator/AP ARM: dts: add the Integrator/AP baseboard clocks ARM: dts: set the 24MHz xtal as parent of the UART clock
