Subject: [PATCH 1/6] dt-bindings: imx6q-pcie: add compatible for IMX8MM support
Date: Fri, 23 Jul 2021 13:49:53 -0700	[thread overview]
Message-ID: <20210723204958.7186-2-tharvey@gateworks.com> (raw)
In-Reply-To: <20210723204958.7186-1-tharvey@gateworks.com>

This adds the DT binding for IMX8MM support to the existing imx6q-pcie
driver which shares most functionality with the IMX8MM.

Additionally a 'fsl,ext-osc' property is defined to note use of an
external oscillator as ref clock vs the internal PLL.
