This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

+* 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>;
