* i2c-omap: Double clear of ARDY status in IRQ handlerRichard woodruff2011-02-231-1/+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.

* i2c-omap: fix static suspend vs. runtime suspendKevin Hilman2011-02-221-0/+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.)

* i2c: Factor out runtime suspend checks from PM operationsMark Brown2011-01-141-48/+20
| | | | | | | | | | When devices use dev_pm_ops the I2C API is implementing standard functionality for integration with runtime PM and for checking for the presence of a per device op. The PM core provides pm_generic_ functions implementing this behaviour - use them to reduce coupling with future PM updates.

* i2c: Convert SCx200 driver from using raw PCI to platform deviceAndres Salomon2011-01-141-120/+80
| | | | | | | | | | | | | | | | | | The SCx200 ACB driver supports ISA hardware as well as PCI. The PCI hardware is CS5535/CS5536 based, and the device that it grabs is handled by the cs5535-mfd driver. This converts the SCx200 driver to use a platform_driver rather than the previous PCI hackery. The driver used to manually track the iface list (via linked list); now it only does this for ISA devices. PCI ifaces are handled through standard driver model lists. It's unclear what happens in case of errors in the old ISA code; rather than pretending the code actually cares, I've dropped the (implicit) ignorance of return values and marked it with a comment.
