+Subject: [PATCH] spi: mt7621: Move SPI driver out of staging
 
-Signed-off-by: John Crispin <blogic@openwrt.org>
+This patch moves the MT7621 SPI driver, which is used on some Ralink /
+MediaTek MT76xx MIPS SoC's, out of the staging directory. No changes to
+the source code are done in this patch.
+
+This driver version was tested successfully on an MT7688 based platform
+with an SPI NOR on CS0 and an SPI NAND on CS1 without any issues (so
+far).
+
+This patch also documents the devicetree bindings for the MT7621 SPI
+device driver.
