    ARM: dts: am33xx: fix SLEWCTRL_FAST pinctrl binding · 424e0f03
    Dave Gerlach authored
    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.
