Subject: [PATCH v2 2/4] dt-bindings: imx6q-pcie: Add multi-pd bindings for imx6sx
Date: Mon, 8 Oct 2018 18:06:20 +0000	[thread overview]
Message-ID: <fb622df91d2e4aa339e8831fb8bcde03327f5bda.1539020938.git.leonard.crestez@nxp.com> (raw)
In-Reply-To: <cover.1539020938.git.leonard.crestez@nxp.com>

The PCIE and PCIE_PHY blocks are in different power domains on imx6sx
and this needs to be described using multi-pd bindings.

This was not required until now because the power-domain of the PCIE
block (DISPLAY) was always on.
