Subject: [PATCH v4 4/6] staging: mt7621-pci: bindings: update doc accordly to last changes
Date: Fri, 13 Mar 2020 21:09:11 +0100	[thread overview]
Message-ID: <20200313200913.24321-5-sergio.paracuellos@gmail.com> (raw)
In-Reply-To: <20200313200913.24321-1-sergio.paracuellos@gmail.com>

Properly update bindings documentation with added 'reset-gpios'
property. Delete also 'perst-gpio' which is not being used anymore.
