[PATCH v2 4/4] pintcrl: support bias-disable of generic and special pins simultaneously

From: Zhiyong Tao
Date: Mon Feb 26 2018 - 03:34:32 EST


For generic pins, parameter "arg" is 0 or 1.
For special pins, bias-disable is set by R0R1,
so we need transmited "00" to set bias-disable
When we set "bias-disable" as high-z property,
the parameter should be "MTK_PUPD_SET_R1R0_00".
