@ -1136,6 +1136,21 @@ When kbuild executes, the following steps are followed (roughly):
resulting in the target file being recompiled for no
obvious reason.
dtc
Create flattend device tree blob object suitable for linking
into vmlinux. Device tree blobs linked into vmlinux are placed
in an init section in the image. Platform code *must* copy the
blob to non-init memory prior to calling unflatten_device_tree().
Example:
#arch/x86/platform/ce4100/Makefile
clean-files := *dtb.S
DTC_FLAGS := -p 1024
obj-y += foo.dtb.o
$(obj)/%.dtb: $(src)/%.dts

EEPROMs (I2C)
Required properties:
- compatible : should be "<manufacturer>,<type>"
If there is no specific driver for <manufacturer>, a generic
driver based on <type> is selected. Possible types are:
24c00, 24c01, 24c02, 24c04, 24c08, 24c16, 24c32, 24c64,
24c128, 24c256, 24c512, 24c1024, spd
- reg : the I2C address of the EEPROM
Optional properties:
- pagesize : the length of the pagesize for writing. Please consult the
manual of your device, that value varies a lot. A wrong value
may result in data loss! If not specified, a safety value of
'1' is used which will be very slow.
- read-only: this parameterless property disables writes to the eeprom
Example:
eeprom@52 {
compatible = "atmel,24c32";
reg = <0x52>;
pagesize = <32>;
};
