Merge branch 'spear/13xx' into next/soc2
* spear/13xx:
pinctrl: SPEAr1310: Fix pin numbers for clcd_high_res
SPEAr: Update MAINTAINERS and Documentation
SPEAr13xx: Add defconfig
SPEAr13xx: Add compilation support
SPEAr13xx: Add dts and dtsi files
pinctrl: Add SPEAr13xx pinctrl drivers
pinctrl: SPEAr: Create macro for declaring GPIO PINS
SPEAr13xx: Add common clock framework support
SPEAr13xx: Add source files
SPEAr13xx: Add header files
Depends on clock, pinctrl and dt branches to go first.
