* i2c-algo-pca: Fix coding style issuesFarid Hammane2010-05-211-18/+18
| | | | | | | | | | | Fix up some coding style issues. i2c-algo-pca.c has been built successfully after applying this patch and the binary object is still exactly the same. Other issues found by checkpatch.pl were voluntarily not fixed, either to keep readability, or because of false positive errors.

* i2c-gpio: Move initialization code to subsys_initcall()Marek Szyprowski2010-05-211-1/+1
| | | | | | | | | | | | | | | | | | | GPIO driven I2C bus can be used for controlling the PMIC chip. The example of such configuration is Samsung Aquila board. This patch moves initialization code to subsys_initcall() to ensure that the i2c bus is available early so the regulators can be quickly probed and available for other devices on their probe() call. Such solution has been proposed by Mark Brown to fix the problem of the regulators not beeing available on the peripheral device probe(): http://lists.infradead.org/pipermail/linux-arm-kernel/2010-March/011971.html Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Reviewed-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* at24: Fall back to byte or word reads if neededJean Delvare2010-05-211-11/+48
| | | | | | | | | | | | | | | | | | | | Increase the portability of the at24 driver by letting it read from EEPROM chips connected to cheap SMBus controllers that support neither raw I2C messages nor even I2C block reads. All SMBus controllers should support either word reads or byte reads, so read support becomes universal, much like with the legacy "eeprom" driver. Obviously, this only works with EEPROM chips up to AT24C16, that use 8-bit offset addressing. 16-bit offset addressing is almost impossible to support on SMBus controllers. I did not add universal support for writes, as I had no immediate need for this, but it could be added later if needed (with the same performance issue as byte and word reads have, of course.)

* i2c-i801: All newer devices have all the optional featuresJean Delvare2010-05-211-12/+6Star
| | | | | | | | | | | | | | Only the oldest devices lack some of the features supported by this driver. List them explicitly, and default to all features enabled for all other chips, including the ones added through sysfs. This will make future driver maintenance easier. In the unlikely event of a not yet supported device not implementing all the features, one can always use the disable_features module parameter to prevent the driver from attempting to use them.
