ARM: dts: AM33XX: Specific pinctrl header The pinctrl IP inside the AM33XX family differs slightly from what is found on OMAP2+. Define a specific header to take account of the differences.

pinctrl: am33xx dt binding: correct include path Using #include <include/...> is a bit odd. It happens to work because the DTC flags include -Iarch/FOO/boot/dts as well as arch/FOO/boot/dts/include and arch/FOO/boot/dts/include/dt-bindings is a symlink to include/dt-bindings.

ARM: dts: am33xx: fix SLEWCTRL_FAST pinctrl binding According to AM335x TRM, Document spruh73l, Revised February 2015, Section 9.2.2 Pad Control Registers, setting bit 6 of the pad control registers actually sets the SLEWCTRL value to slow rather than fast as the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for completeness. Current users of the macro (i2c and mdio) are left unmodified as SLEWCTRL_FAST was the macro used and actual desired state. Tested on am335x-gp-evm with no difference in software performance seen.
