Subject: [PATCH 6/7] [POWERPC] booting-without-of: add FHCI USB, FSL MCU, FSL UPM and GPIO LEDs bindings
Date: Sat, 24 May 2008 04:30:08 +0400 [thread overview]
Message-ID: <20080524003008.GA20493@zarina> (raw)
In-Reply-To: <20080524002825.GA636@zarina>
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 usb 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:
+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+ - fsl,lowspeed-clock : specifies the low speed USB clock source:
+ "none": clock source is disabled
+ "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+ "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+ - fsl,usb-mode : (optional) so far acceptable value is "host" only
+ (this is default mode if property is absent).
+ - 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 {
+ compatible = "fsl,mpc8360-qe-usb", "fsl,mpc8323-qe-usb";
+ reg = <0x6c0 0x40 0x8b00 0x100>;

+ - reg : should specify I2C address (0x0a).
+ - #gpio-cells : should be 2.
+ - gpio-controller : should be present;

+ Example:
+
+ upm@1,0 {
