From 00ac9562158e8541d60e91eb72aa9ed0674d4a6a Mon Sep 17 00:00:00 2001 From: Kurt Kanzenbach Date: Mon, 13 Nov 2017 08:47:21 +0100 Subject: spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities The driver as well as the controller support the SPI lsb first mode. However, it's not possible to configure it e.g. when using spidev. Adding this flag to mode_bits resolves the issue and lsb first mode can be used.

The data field of an of_device_id structure has type const void *, so there is no need for a const-discarding cast when putting const values into such a structure. Done using Coccinelle.
