* of: assume big-endian properties, adding conversions where necessaryJeremy Kerr2010-02-091-2/+2
| | | | | | | | | | | | | | | | Properties in the device tree are specified as big-endian. At present, the only platforms to support device trees are also big-endian, so we've been acessing the properties as raw values. We'd like to add device tree support to little-endian platforms too, so add endian conversion to the sites where we access property values in the common of code. Compiled on powerpc (ppc44x_defconfig & ppc64_defconfig) and arm (fdt support only for now).

* drivers/of: Add the of_find_i2c_device_by_node function.Jon Smirl2009-01-091-0/+19
| | | | | | | | | | | | | The of_find_i2c_device_by_node function allows you to follow a reference in the device tree to an i2c device node and then locate the linux device instantiated by the device tree. Example use: an I2S bus driver finding the i2c_device instance for a codec described by a device tree node. This was waiting for Anton's i2c patches that were just added.

* of/i2c: Fill the archdata for I2C devicesAnton Vorontsov2008-12-031-0/+11
| | | | | | | | | For I2C devices we just setting the node pointer in the archdata. This is needed so that the I2C devices could find their OF tree nodes.

* of: Format string bug in drivers/of/of_i2c.cJon Smirl2008-10-211-1/+1
| | | | | | | | | Format string bug. Not exploitable, as this is only writable by root, but worth fixing all the same. See 326f6a5c9c9e1a62aec37bdc0c3f8d53adabe77b Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* of: adapt of_find_i2c_driver() to be usable by SPI alsoGrant Likely2008-07-251-61/+3
| | | | | | | | SPI has a similar problem as I2C in that it needs to determine an appropriate modalias value for each device node. This patch adapts the of_i2c of_find_i2c_driver() function to be usable by of_spi also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* powerpc/mpc5200: Fix wrong 'no interrupt' handling in of_i2cWolfram Sang2008-07-221-2/+0
| | | | | | | | | | | If an I2C device node does not specify an interrupt, the .irq member of the board_info struct was set to -1. This caused crashes on following irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map. (Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)

* rtc-ds1374: rename device to just "ds1374"Jean Delvare2008-06-061-1/+0
| | | | | | | | | | | | | | | | Change the name of the device from "rtc-ds1374" to just "ds1374", to match what all other RTC drivers do. I seem to remember that this name was chosen to avoid possible confusion with an older ds1374 driver, but that driver was removed 3 months ago.

Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for the i2c API". If i2c-core is compiled as a module, the helper needs to be compiled as a module, as well. Rename i2c.c to of_i2c.c to avoid name space conflict.
