[PATCH 0/2] pinctrl: pinctrl-zynqmp: Revert output-enable and bias-high-impedance support

Posted by Sai Krishna Potthuri 3 years, 5 months ago

Having support for output-enable and bias-high-impedance properties
causing system hang with older Xilinx ZynqMP Platform Management Firmware
because there is missing autodetection feature.
When this feature is implemented, support for these two properties should
bring back.

    bias-high-impedance"
