+
+With the ath79 target getting converted to pure OF, we can drop all the
+platform data code and add the missing OF bits to the driver. We also add
+a irq domain for the PCI/e controllers cascade, thus making it usable from
+dts files.

+
+This adds missing GMAC register definitions for the Qualcomm Atheros
+QCA955X series MIPS SoCs.

+They originate from the platforms U-Boot code and the AVM FRITZ!WLAN
+Repeater 450E's GPL tarball.

+Subject: [PATCH] spi: ath79: remove spi-master setup and cleanup assignment
+
+This removes the assignment of setup and cleanup functions for the ath79
+target. Assigning the setup-method will lead to 'setup_transfer' not
+being assigned in spi_bitbang_init.
+
+Also drop the redundant cleanup assignment, as this also happens in
+spi_bitbang_init.

+
+The QCA9550 family of SoCs have a slightly different reset
+sequence compared to older chips.
+
+Normally the bootloader performs this sequence, however
+some bootloader implementation expect the operating system
+to clear the reset.
+
+Also get the resets from OF to support handling of the second
+PCIe root-complex on the QCA9558.

+From 66e584435ac0de6e0abeb6d7166fe4fe25d6bb73 Mon Sep 17 00:00:00 2001
+From: Jonas Gorski <jogo@openwrt.org>
+Date: Tue, 16 Jun 2015 13:15:08 +0200
+Subject: [PATCH] phy/mdio-bitbang: prevent rescheduling during command
+
+It seems some phys have some maximum timings for accessing the MDIO line,
+resulting in bit errors under cpu stress. Prevent this from happening by
+disabling interrupts when sending commands.
+

+Subject: [RFC] serial: core: add support for boot console with arbitrary
+ baud rates
+
+The Arduino Yun uses a baud rate of 250000 by default. The serial is
+going over the Atmel ATmega and is used to connect to this chip.
+Without this patch Linux wants to switch the console to 9600 Baud.
+
+With this patch Linux will use the configured baud rate and not a
+default one specified in uart_register_driver().

+Subject: [PATCH] ath79: ar8216: make switch register access atomic
+
+due to some unknown reason these register accesses sometimes fail
+on the integrated switch without this patch.
+
+THIS ONLY WORKS ON ATH79 AND MAY BREAK THE DRIVER ON OTHER PLATFORMS!
+The mdio bus on ath79 works in polling mode and doesn't rely on
+any interrupt. This patch breaks the driver on any mdio master
+with interrupts used.
