Subject: [PATCH 04/57] MIPS: ralink: adds a bootrom dumper module
|
||||||
|
|

||||||
|
a SoC via debugfs.

Subject: [PATCH 18/57] MIPS: ralink: workaround DTB memory issue
|
||||||
|
|
||||||
|
If the DTB is too big a bug happens on boot when init ram is freed.
|
||||||
|
This is a temporary fix until the real cause is found.

Subject: [PATCH 21/57] MIPS: ralink: add cpu frequency scaling
|
||||||
|
|
||||||
|
This feature will break udelay() and cause the delay loop to have longer delays
|
||||||
|
when the frequency is scaled causing a performance hit.

Subject: [PATCH 23/57] MIPS: ralink: mt7620: fix usb issue during frequency
|
||||||
|
scaling
|
||||||
|
|
||||||
|
If the USB HCD is running and the cpu is scaled too low, then the USB stops
|
||||||
|
working. Increase the idle speed of the core to fix this if the kernel is
|
||||||
|
built with USB support.
|
||||||
|
|
||||||
|
The values are taken from the Ralink SDK Kernel.

Subject: [PATCH 29/57] serial: of: allow au1x00 and rt288x to load from OF
|
||||||
|
|
||||||
|
In order to make serial_8250 loadable via OF on Au1x00 and Ralink WiSoC we need
|
||||||
|
to default the iotype to UPIO_AU.

Subject: [PATCH 34/57] NET: add of_get_mac_address_mtd()
|
||||||
|
|
||||||
|
Many embedded devices have information such as mac addresses stored inside mtd
|
||||||
|
devices. This patch allows us to add a property inside a node describing a
|
||||||
|
network interface. The new property points at a mtd partition with an offset
|
||||||
|
where the mac address can be found.

+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 ]

|
+

Subject: [PATCH 47/57] GPIO: MIPS: ralink: add gpio driver for ralink SoC
|
||||||
|
|
||||||
|
Add gpio driver for Ralink SoC. This driver makes the gpio core on
|
||||||
|
RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

+Ralink SoC RT2880 SPI master controller.
|
||||||
|
+
|
||||||
|
+This SPI controller is found on most wireless SoCs made by ralink.
|
||||||
|
+
|
||||||
|
+Required properties:
|
||||||
|
+- compatible : "ralink,rt2880-spi"
|
||||||
|
+- reg : The register base for the controller.
|
||||||
|
+- #address-cells : <1>, as required by generic SPI binding.
|
||||||
|
+- #size-cells : <0>, also as required by generic SPI binding.
|
||||||
|
+
|
||||||
|
+Child nodes as per the generic SPI binding.
|
||||||
|
+
|
||||||
|
+Example:
|
||||||
|
+
|
||||||
|
+ spi@b00 {
|
||||||
|
+ compatible = "ralink,rt2880-spi";
|
||||||
|
+ reg = <0xb00 0x100>;
|
||||||
|
+
|
||||||
|
+ #address-cells = <1>;
|
||||||
|
+ #size-cells = <0>;
|
||||||
|
+
|
||||||
|
+ m25p80@0 {
|
||||||
|
+ compatible = "m25p80";
|
||||||
|
+ reg = <0>;
