ARM: remove u300 platform
The Ericsson U300 platform was one of two ARM929 based SoC platforms for mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP into ST-Ericsson, the other one being the ST Nomadik. The platform was not widely adopted in Linux based systems and was replaced with the far superior ST-Ericsson U8500 in 2011, but Linus Walleij kept maintaining the code for the whole time. Linus continues to use the Nomadik machine, but decided to drop u300 from the kernel as part of this year's spring cleaning. Thanks for having maintained it all these years.

ST-Ericsson U300 Device Tree Bindings
|
||||
|
||||
For various board the "board" node may contain specific properties
|
||||
that pertain to this particular board, such as board-specific GPIOs
|
||||
or board power regulator supplies.
|
||||
|
||||
Required root node property:
|
||||
|
||||
compatible="stericsson,u300";
|
||||
|
||||
Required node: syscon
|
||||
This contains the system controller.
|
||||
- compatible: must be "stericsson,u300-syscon".
|
||||
- reg: the base address and size of the system controller.
|
||||
|
||||
Boards with the U300 SoC include:
|
||||
|
||||
S365 "Small Board U365":
|
||||
|
||||
Required node: s365
|
||||
This contains the board-specific information.
|
||||
- compatible: must be "stericsson,s365".
|
||||
- vana15-supply: the regulator supplying the 1.5V to drive the
|
||||
board.
|
||||
- syscon: a pointer to the syscon node so we can access the
|
||||
syscon registers to set the board as self-powered.
|
||||
|
||||
Example:
|
||||
|
||||
/ {
|
||||
model = "ST-Ericsson U300";
|
||||
compatible = "stericsson,u300";
|
||||
#address-cells = <1>;
|
||||
#size-cells = <1>;
|
||||
|
||||
s365 {
|
||||
compatible = "stericsson,s365";
|
||||
vana15-supply = <&ab3100_ldo_d_reg>;
|
||||
syscon = <&syscon>;
|
||||
};
|
||||
|
||||
syscon: syscon@c0011000 {
|
||||
compatible = "stericsson,u300-syscon";
|
||||
reg = <0xc0011000 0x1000>;
|
||||
};
|
||||
};
