Note that this relies on a few outstanding changes: * Needs (spi: s3c64xx: fix broken "cs_gpios" usage in the driver) and (spi: s3c64xx: for DT platofrms always get the chipselect info from DT node) to work properly and match the documented bindings. See and Signed-off-by: Doug Anderson Tested-by: Javier Martinez Canillas Tested-by: Tushar Behera --- Changes in v3: - Added aliases for tps65090 regulators as per Tushar.
