Subject: [PATCH v1 06/14] net: macb: add polarfire soc reset support
Date: Thu, 30 Jun 2022 09:05:25 +0100	[thread overview]
Message-ID: <20220630080532.323731-7-conor.dooley@microchip.com> (raw)
In-Reply-To: <20220630080532.323731-1-conor.dooley@microchip.com>

To date, the Microchip PolarFire SoC (MPFS) has been using the
cdns,macb compatible, however the generic device does not have reset
support. Add a new compatible & .data for MPFS to hook into the reset
functionality added for zynqmp support (and make the zynqmp init
function generic in the process).
