2011-05-18drivercore: revert addition of of_match to struct deviceGrant Likely1-3/+6
Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-05-01i2c-i801: Move device ID definitions to driverJean Delvare1-0/+5
Move the SMBus device ID definitions of recent devices from pci_ids.h to the i2c-i801.c driver file. They don't have to be shared, as they are clearly identified and only used in this driver. In the future, such IDs will go to i2c-i801 directly. This will make adding support for new devices much faster and easier, as it will avoid cross- subsystem patch sets and merge conflicts.

2011-04-17i2c-algo-bit: Call pre/post_xfer for bit_testAlex Deucher1-3/+19
Apparently some distros set i2c-algo-bit.bit_test to 1 by default. In some cases this causes i2c_bit_add_bus to fail and prevents the i2c bus from being added. In the radeon case, we fail to add the ddc i2c buses which prevents the driver from being able to detect attached monitors. The i2c bus works fine even if bit_test fails. This is likely due to gpio switching that is required and handled in the pre/post_xfer hooks, so call the pre/post_xfer hooks in the bit test as well.

The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that the mfd's platform_data is marked __devinitdata.

The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code.

2011-03-21ARM: pxa2xx: reorganize I2C filesSebastian Andrzej Siewior1-1/+1
This patch moves the platform data definition from arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so it can be accessed from x86 the same way as on ARM.

Adds I2C bus driver for nVidia Tegra SoCs. Tegra includes 4 I2C controllers, one of which is inside the Dynamic Voltage Controller and has a slightly different register map. Signed-off-by: Colin Cross <ccross@android.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2011-02-23i2c-omap: Double clear of ARDY status in IRQ handlerRichard woodruff1-1/+5
This errata occurs when the ARDY interrupt generation is enabled. At the begining of every new transaction the ARDY interrupt is cleared. On continuous i2c transactions where after clearing the ARDY bit from I2C_STAT register (clearing the interrupt), the IRQ line is reasserted and the I2C_STAT[ARDY] bit set again on 1. In fact, the ARDY status bit is not cleared at the write access to I2C_STAT[ARDY] and only the IRQ line is deasserted and then reasserted. This is not captured in the usual errata documents. The workaround is to have a double clear of ARDY status in irq handler.

2011-02-22i2c-omap: fix static suspend vs. runtime suspendKevin Hilman1-0/+28
When runtime PM is enabled, each OMAP i2c device is suspended after each i2c xfer. However, there are two cases when the static suspend methods must be used to ensure the devices are suspended: 1) runtime PM is disabled, either at compile time or dynamically via /sys/devices/.../power/control. 2) an i2c client driver uses i2c during it's suspend callback, thus leaving the i2c driver active (NOTE: runtime suspend transitions are disabled during system suspend, so i2c activity during system suspend will runtime resume the device, but not runtime (re)suspend it.) Since the actual work to suspend the device is handled by the subsytem, call the bus methods to take care of it. NOTE: This takes care of a known suspend problem on OMAP3 where the TWL RTC driver does i2c xfers during its suspend path leaving the i2c driver in an active state (since runtime suspend transistions are disabled.)
