Subject: [PATCH 6/7] [POWERPC] booting-without-of: add FHCI USB, FSL MCU, FSL UPM and GPIO LEDs bindings
Date: Mon, 19 May 2008 21:47:14 +0400 [thread overview]
Message-ID: <20080519174714.GF28185@polina.dev.rtsoft.ru> (raw)
In-Reply-To: <20080519174558.GA26229@polina.dev.rtsoft.ru>
This patch adds few bindings for the new drivers to be submitted through
appropriate maintainers.

+ Required properties:
+ - compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb";
+ - reg : the first two cells should contain gtm registers location and
+ length, the next two two cells should contain PRAM location and
+ length.
+ - interrupts : should contain USB interrupt.
+ - interrupt-parent : interrupt source phandle.
+ - fsl,fullspeed-clock : specifies the full speed USB clock source in
+ "clk<num>" or "brg<num>" format.
+ - fsl,lowspeed-clock : specifies the low speed USB clock source in
+ "clk<num>" or "brg<num>" format.
+ - fsl,usb-mode : should be "host".
+ - linux,hub-power-budget : optional, USB power budget for the root hub
+ in mA.
+ - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
+ USBRN, SPEED (optional), and POWER (optional).

+ Example:
+
+ usb@6c0 {
