OF support for tsc2007

OF support for tsc2007

[Gary Thomas]

I'm trying to use the TSC2007 (actually TSC2003) on a PowerPC
based platform.  Sadly, the current driver (as of .30-rc4)
does not seem to be OF aware.

Jon Smirl on the PPC list suggested I ask here.

Any help or ideas?

n.b. at the moment, I'm not subscribed to this list, so please
CC me on any replies.

Thanks

I thought you said it was an old-style driver that hadn't been
converted to new style?

i2c drivers don't need to be OF aware.  The code in
drivers/of/of_i2c.c set things up for you.
You need a driver tree entry like this:

		i2c@3d40 {
			#address-cells = <1>;
			#size-cells = <0>;
			compatible = "fsl,mpc5200b-i2c","fsl,mpc5200-i2c","fsl-i2c";
			cell-index = <1>;
			reg = <0x3d40 0x40>;
			interrupts = <0x2 0x10 0x0>;
			interrupt-parent = <&mpc5200_pic>;
			fsl5200-clocking;

			rtc@51 {
				device_type = "rtc";
				compatible = "epson,rtc8564";
				reg = <0x51>;
			};
			eeprom@52 {
				compatible = "atmel,24c32", "eeprom";
				reg = <0x52>;
			};
		};

My question remains; how do I provide the platform_data this
driver wants on an OF based platform?
