Subject: [PATCH 3/4] pinctrl: pinctrl-zynq: Add support for 'power-source' parameter
Date: Wed, 21 Jul 2021 17:22:32 +0530	[thread overview]
Message-ID: <1626868353-96475-4-git-send-email-lakshmi.sai.krishna.potthuri@xilinx.com> (raw)
In-Reply-To: <1626868353-96475-1-git-send-email-lakshmi.sai.krishna.potthuri@xilinx.com>

Add support for generic pin parameter 'power-source'.
To maintain the backward compatibility, 'io-standard' parameter is still
supported in the driver.
