+Subject: [PATCH] ath79: add Mikrotik rb4xx series drivers
+
+This adds 3 Mikrotik rb4xx series drivers as follows:
+
+rb4xx-cpld: This is in the mfd subsystem, and is the parent CPLD device
+that interfaces between the SoC SPI bus and its two children below.
+rb4xx-gpio: This is the GPIO expander.
+rb4xx-nand: This is the NAND driver.
+
+The history of this code comes in three phases.
+
+1. The first is a May 2015 attempt to push the equivalient ar71xx rb4xx
+drivers upstream. See https://lore.kernel.org/patchwork/patch/940880/.
+
+Module-author: Gabor Juhos <juhosg@openwrt.org>
+Module-author: Imre Kaloz <kaloz@openwrt.org>
+Module-author: Bert Vermeulen <bert@biot.com>
+
+2. Next several ar71xx patches were applied bringing the code current.

+Submitted-by: Felix Fietkau <nbd@nbd.name>
+
+3. Finally a heavy refactor to split the driver into the three new
+subsystems, and updated to work with the device tree configuration, plus
+updates and review feedback incorporated
