mtd: physmap_of: Loop through all "reg" tuples for mapping

2010-10-25T00:12:46+00:00

This patch changes the loop over the "reg" tuples to not exit
directly upon of_address_to_resource() failure but to continue
with the next "reg" tuple instead. This failure could be due to
size = 0, which might be passed via the device-tree.

This is needed for boards, where a "reg" tuple might have size 0
(of_address_to_resource() returns with EINVAL when size = 0).

Example:

Fully equipped board:

	reg = <0 0x00000000 0x00400000
	       0 0x00400000 0x00400000>;

Partially equipped board:

	reg = <0 0x00000000 0x00400000
	       0 0x00400000 0x00000000>;

This could be the case on boards with runtime detection of
multiple NOR flash configurations where the detected flash size
is inserted into the dtb in U-Boot.

mtd: Fix endianness issues from device tree

2010-10-24T23:55:56+00:00

This patch adds the appropriate conversions to correct the endianness
issues in the MTD driver whenever it accesses the device tree (which is
always big endian).

of: fix missing headers for of_address_to_resource() in MTD and SysACE drivers

2010-08-17T19:16:47+00:00

The drivers for Xilinx' SystemACE and physically mapped MTDs were missing
prototypes for of_address_to_resource(). This patch adds the necessary
headers.

of/device: Replace struct of_device with struct platform_device

2010-08-06T15:25:50+00:00

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Also fixed up one line in arch/powerpc/kernel/vio.c to use the

of: Remove duplicate fields from of_platform_driver

2010-05-22T06:10:40+00:00

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

of: Always use 'struct device.of_node' to get device node pointer.

2010-05-18T22:10:44+00:00

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated.  This patch
makes all readers of these elements use device.of_node instead.

(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)
