Subject: [PATCH 1/5] dt-bindings: spi/spi-pxa2xx: add PXA2xx SSP SPI Controller
Date: Mon, 10 Sep 2018 13:59:31 +0200	[thread overview]
Message-ID: <20180910115935.163121-2-lkundrak@v3.sk> (raw)
In-Reply-To: <20180910115935.163121-1-lkundrak@v3.sk>

This is the SPI controller found on Marvel MMP2 and perhaps more
platforms.

+PXA2xx SSP SPI Controller

+Required properties:
+- compatible: Must be "marvell,mmp2-ssp".
+- reg: Offset and length of the device's register set.
+- interrupts: Should be the interrupt number.
+- clocks: Should contain a single entry describing the clock input.
+- #address-cells:  Number of cells required to define a chip select address.
+- #size-cells: Should be zero.

+Optional properties:
+- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,
