++* Qualcomm Atheros AR7100 PCI express root complex

++Required properties:
++- compatible: should contain "qcom,ar7100-pci" to identify the core.

++- reg-names: Definition: Must include the following entries

++- #address-cells: set to <3>
++- #size-cells: set to <2>
++- ranges: ranges for the PCI memory and I/O regions

++- #interrupt-cells: set to <1>
++- interrupt-controller: define to enable the builtin IRQ cascade.
++
++Optional properties:
++- interrupt-parent: phandle to the MIPS IRQ controller

++* Qualcomm Atheros AR724X PCI express root complex
++
++Required properties:
++- compatible: should contain "qcom,ar7240-pci" to identify the core.
++- reg: Should contain the register ranges as listed in the reg-names property.
++- reg-names: Definition: Must include the following entries
++ - "crp_base" Configuration registers
++ - "ctrl_base" Control registers
++ - "cfg_base" IO Memory
++- #address-cells: set to <3>
++- #size-cells: set to <2>
++- ranges: ranges for the PCI memory and I/O regions
++- interrupt-map-mask and interrupt-map: standard PCI
++ properties to define the mapping of the PCIe interface to interrupt
++ numbers.
++- #interrupt-cells: set to <1>
++- interrupt-parent: phandle to the MIPS IRQ controller
++
++Optional properties:
++- interrupt-controller: define to enable the builtin IRQ cascade.
++
++* Example for qca9557

+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.

+On AR934x, the MDIO reference clock can be configured to a fixed 100 MHz
+clock. If that feature is not used, it defaults to the main reference
+clock, like on all other SoC.

+Date: Sat, 23 Jun 2018 15:04:09 +0200
+Subject: [PATCH 28/33] MIPS: ath79: drop machfiles
+
+With the target now being fully OF based, we can drop the legacy mach
+files. Boards can now boot fully of devicetree files.

+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.

+Subject: [PATCH 30/33] MIPS: ath79: drop platform device registration code
+
+With the target now being fully OF based, we can drop the legacy platform
+device registration code. All devices and their drivers are now probed
+via OF.

+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.
