+
+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.

+Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
+
+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.

+Subject: [PATCH 24/33] MIPS: ath79: make specifying the reference clock in DT
+ optional
+
+It can be autodetected for many SoCs using the strapping options.
+If the clock is specified in DT, the autodetected value is ignored

+Subject: [PATCH 27/33] MIPS: ath79: drop legacy IRQ code
+
+With the target now being fully OF based, we can drop the legacy IRQ code.
+All IRQs are now handled via the new irqchip drivers.

+Subject: [PATCH 29/33] MIPS: ath79: drop legacy pci code
+
+With the target now being fully OF based, we can drop the legacy pci
+platform code. The only bits that we need to keep is the fixup code
+which we move to its own code file.

+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.
