Re: [PATCH] pinctrl: zynqmp: Add support for output-enable and bias-high-impedance

st 15. 6. 2022 v 11:52 odesílatel Michal Simek monstr@monstr.eu napsal:

From: Ashok Reddy Soma ashok.reddy.soma@xilinx.com

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.
