Adrian Schmutzler 7d7aa2fd92 brcm2708: rename target to bcm27xx
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.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

+* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
+
+The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
+an active array size of 3280H x 2464V. It is programmable through I2C
+interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
+data lanes.
+
+Required Properties:
+- compatible: value should be "sony,imx219" for imx219 sensor
+- reg: I2C bus address of the device
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
+- AVDD-supply: Analog voltage supply, 2.8 volts
+- DVDD-supply: Digital core voltage supply, 1.2 volts
+
+Optional Properties:
+- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
+ released after all supplies are applied.
+ This is an active high signal to the imx219.
+
+The imx219 device node should contain one 'port' child node with
+an 'endpoint' subnode. For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Endpoint node required properties for CSI-2 connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
+- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
+ supported)
+
+Example:
+ sensor@10 {
+ compatible = "sony,imx219";
+ reg = <0x10>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&imx219_clk>;
+ clock-names = "xclk";
+ xclr-gpios = <&gpio_sensor 0 0>;
+ DOVDD-supply = <&vgen4_reg>; /* 1.8v */
+ AVDD-supply = <&vgen3_reg>; /* 2.8v */
+ DVDD-supply = <&vgen2_reg>; /* 1.2v */
+
+ imx219_clk: camera-clk {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <24000000>;
+ };
+
+ port {
+ sensor_out: endpoint {
+ remote-endpoint = <&csiss_in>;
+ clock-lanes = <0>;
+ data-lanes = <1 2>;
+ };
+ };
+ };
