* [PATCH 2/2] ARM i.MX25: Add devicetree
2012-09-24 6:40 [PATCH] i.MX25 devicetree support Sascha Hauer

This adds a i.MX25 dtsi file along with the i.MX25 clock tree
documentation. The devicetree should be fairly complete for:
- uart
- fec
- i2c
- spi
- pwm
- nand
- gpio
- wdog
- esdhc
- flexcan
The more exotic devices currently miss clock bindings.

+* Clock bindings for Freescale i.MX25
+
+Required properties:
+- compatible: Should be "fsl,imx25-ccm"
+- reg: Address and length of the register set
+- interrupts: Should contain CCM interrupt
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. The following is a full list of i.MX6Q
+clocks and IDs.

A couple of trivial comments below though.

When the series gets rebased on imx multi-platform branch, the property
needs to be:
compatible = "fsl,imx25-i2c", "fsl,imx21-i2c";

We can add a EMI node being parent of NAND to show how nand connects
to SoC.

Changes since v1:
- Fix typo i.MX6Q -> i.MX25
- Add EMI bus and NFC controller on it
- change i2c compatible from i.MX1 to i.MX21

This adds a i.MX25 dt machine descriptor and changes the clock
support to optionally initialize from dt.

This adds a i.MX25 dtsi file along with the i.MX25 clock tree
documentation. The devicetree should be fairly complete for:
- uart
- fec
- i2c
- spi
- pwm
- nand
- gpio
- wdog
- esdhc
- flexcan
The more exotic devices currently miss clock bindings.
