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 BCM6328 pin controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: Must be "brcm,bcm6328-pinctrl".
|
|
+- reg: Register specifies of dirout, dat, mode, mux registers.
|
|
+- reg-names: Must be "dirout", "dat", "mode", "mux".
|
|
+- gpio-controller: Identifies this node as a GPIO controller.
|
|
+- #gpio-cells: Must be <2>
|
|
+
|
|
+Example:
|
|
+
|
|
+pinctrl: pin-controller@10000080 {
|
|
+ compatible = "brcm,bcm6328-pinctrl";
|
|
+ reg = <0x10000080 0x8>,
|
|
+ <0x10000088 0x8>,
|
|
+ <0x10000098 0x4>,
|
|
+ <0x1000009c 0xc>;
|
|
+ reg-names = "dirout", "dat", "mode", "mux";
|
|
+
|
|
+ gpio-controller;
|
|
+ #gpio-cells = <2>;
