Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported.

tps65010_remove() calls i2c_get_clientdata(client) but the client data is never set during initialization, so it gets a NULL pointer at best. I guess it was never spotted because the tps65010 driver is typically not built modular so this function is discarded.

The separation between algorithm and adapter was unsharp at places. This was partly hidden by the fact, that the ISA-driver allowed just one instance and had all private data in static variables. This patch makes neccessary preparations to add a platform driver on top of the algorithm, while still supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be tested except that it builds. Concerning the core struct i2c_algo_pca_data: - A private data field was added, all hardware dependant data may go here. Similar to other algorithms, now a pointer to this data is passed to the adapter's functions. In order to make as less changes as possible to the ISA-driver, it leaves the private data empty and still only uses its static variables. - A "reset_chip" function pointer was added; such a functionality must come from the adapter, not the algorithm. - use a variable "i2c_clock" instead of a function pointer "get_clock", allowing for write access to a default in case a wrong value was supplied. In the algorithm-file: - move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h" - now using per_instance timeout values (i2c_adap->timeout) - error messages specify the device, not only the driver name - restructure initialization to easily support "i2c_add_numbered_adapter" - drop "retries" and "own" (i2c address) as they were unused (The state-machine for I2C-communication was not touched.) In the ISA-driver: - adapt to new algorithm Signed-off-by: NWolfram Sang <w.sang@pengutronix.de> Signed-off-by: NJean Delvare <khali@linux-fr.org>

two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: Neric miao <eric.miao@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

I have recently bought some USB PIDs from EZPrototypes for my USB projects and one will be for the i2c-tiny-usb. I have not yet started to use the new one in the official i2c-tiny-usb firmware since i think it makes sense to get the change into the kernel before releasing a modified firmware. This patch adds support for the EZPrototypes USB vid/pid pair used in later i2c-tiny-usb firmware versions (avrusb v1.06 and up, usbtiny v2.06 and up).

If an I2C interrupt happens between disabling interface clock and functional clock, the interrupt handler will produce an external abort on non-linefetch error when trying to access driver registers while interface clock is disabled. This patch fixes the problem by saving and disabling i2c-omap interrupt before turning off the clocks. Also disable functional clock before the interface clock as suggested by Paul Walmsley. Patch also renames enable/disable_clocks functions to unidle/idle functions. Note that the driver is currently not taking advantage of the idle interrupts. To use the idle interrupts, driver would have to enable interface clock based on the idle interrupt and dev->idle flag. This patch has been tested in linux-omap tree with various omaps.
