This target has full device tree support, thus reducing the number of patches needed for bcm63xx, in which there's a patch for every board. The intention is to start with a minimal amount of downstream patches and start upstreaming all of them. Current status: - Enabling EHCI/OHCI on BCM6358 causes a kernel panic. - BCM63268 lacks Timer Clocks/Reset support. - No PCI/PCIe drivers. - No ethernet drivers.

+* Broadcom BCM6358 pin controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: Must be "brcm,bcm6358-pinctrl".
|
|
+- reg: Register specifiers of dirout, dat registers.
|
|
+- reg-names: Must be "dirout", "dat".
|
|
+- brcm,gpiomode: Phandle to the shared gpiomode register.
|
|
+- gpio-controller: Identifies this node as a gpio-controller.
|
|
+- #gpio-cells: Must be <2>.
|
|
+
|
|
+Example:
|
|
+
|
|
+pinctrl: pin-controller@fffe0080 {
|
|
+ compatible = "brcm,bcm6358-pinctrl";
|
|
+ reg = <0xfffe0080 0x8>,
|
|
+ <0xfffe0088 0x8>,
|
|
+ <0xfffe0098 0x4>;
|
|
+ reg-names = "dirout", "dat";
|
|
+ brcm,gpiomode = <&gpiomode>;
|
|
+
|
|
+ gpio-controller;
|
|
+ #gpio-cells = <2>;
|
|
+};
|
|
+
|
|
+gpiomode: syscon@fffe0098 {
|
|
+ compatible = "brcm,bcm6358-gpiomode", "syscon";
|
|
+ reg = <0xfffe0098 0x4>;
