From 123462e5e534d6e17b1b7d2006734bbe54b03e0a Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma <ashok.reddy.soma@xilinx.com> Date: Wed, 15 Jun 2022 11:52:28 +0200 Subject: [PATCH] pinctrl: zynqmp: Add support for output-enable and bias-high-impedance Add support to handle 'output-enable' and 'bias-high-impedance' configurations. DT property output-enable brings out the pins from tri-state, whereas bias-high-impedance changes the pins state to tri-state.
