Enable testing kernel. Delete upstreamed patches: 0098-disable_cm.patch can be dropped, upstream fixed CM handling. Fix compile errors by using new kernel APIs. Fix fuzz by manually editing patches to ensure the code goes in the right place. For 721-NET-no-auto-carrier-off-support.patch, revert upstream commit a307593a6 to keep the OpenWrt ralink driver operational. Add mt7621-pci-phy patch to select REGMAP_MMIO as discussed in PR #3693 and #3952. Rename patches to follow the 3-digit classification from the OpenWrt Developer Guide. Run automatic quilt refresh.

+Ralink SoC GPIO controller bindings
|
|
+
|
|
+Required properties:
|
|
+- compatible:
|
|
+ - "ralink,rt2880-gpio" for Ralink controllers
|
|
+- #gpio-cells : Should be two.
|
|
+ - first cell is the pin number
|
|
+ - second cell is used to specify optional parameters (unused)
|
|
+- gpio-controller : Marks the device node as a GPIO controller
|
|
+- reg : Physical base address and length of the controller's registers
|
|
+- interrupt-parent: phandle to the INTC device node
|
|
+- interrupts : Specify the INTC interrupt number
|
|
+- ralink,num-gpios : Specify the number of GPIOs
|
|
+- ralink,register-map : The register layout depends on the GPIO bank and actual
|
|
+ SoC type. Register offsets need to be in this order.
|
|
+ [ INT, EDGE, RENA, FENA, DATA, DIR, POL, SET, RESET, TOGGLE ]
|
|
+
|
|
+Optional properties:
|
|
+- ralink,gpio-base : Specify the GPIO chips base number
|
|
+
|
|
+Example:
|
|
+
|
|
+ gpio0: gpio@600 {
|
|
+ compatible = "ralink,rt5350-gpio", "ralink,rt2880-gpio";
|
|
+
|
|
+ #gpio-cells = <2>;
|
|
+ gpio-controller;
|
|
+
|
|
+ reg = <0x600 0x34>;
|
|
+
|
|
+ interrupt-parent = <&intc>;
|
|
+ interrupts = <6>;
|
|
+
|
|
+ ralink,gpio-base = <0>;
|
|
+ ralink,num-gpios = <24>;
|
|
+ ralink,register-map = [ 00 04 08 0c
|
|
+ 20 24 28 2c
|
|
+ 30 34 ];
|
|
+
|
|
+ };
