From 765afe7fb3f9d6c030091401b6511eebda06db2d Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Wed, 13 Oct 2021 18:14:17 +0200 Subject: [PATCH] spi: fsl_dspi: add new compatible fsl, ls1021a-v1.0-dspi The official ls1028a binding of the driver uses the following as compatibles: compatible = "fsl,ls1028a-dspi", "fsl,ls1021a-v1.0-dspi"; Add the missing compatible to the driver and update the device tree. We can use the fallback "fsl,ls1021a-v1.0-dspi", because the endianness is determined by the little-endian property and not by the compatible string itself. Further, we won't need and specific details on the DMA configuration (which is different on the LS1021A). If it's ever needed, we can later add the more specific "fsl,ls1028a-dspi" compatible to the driver.
