[PATCH v2 1/4] ARM: pxa3xx: dts: Add defines for pinctrl-single,bias-pull{up,down}

[Daniel Mack <daniel@xxxxxxxxxx>]

This allows users of the pinctrl driver to specify either

  pinctrl-single,bias-pullup = MPF_PULL_UP;

or

  pinctrl-single,bias-pulldown = MPF_PULL_DOWN;

To activate the pull bits in the MFP registers.
