| * i2c: Add module.h to modular files prev. implicitly getting itPaul Gortmaker2011-10-313-0/+3
| | | | | | | | | | | | | | | | | | | | These files use interfaces from linux/module.h, so they must include that file to avoid build errors when the implicit presence of module.h is removed.

| * i2c: add export.h to i2c-boardinfo.c for EXPORT_SYMBOLPaul Gortmaker2011-10-311-0/+1
| | | | | | | | | | | | | | | | | | With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

| * | | mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann2011-10-241-1/+0
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently have two symbols to control compilation the MFD subsystem, MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.

This bit indicates whether an i2c transaction has completed; on the DB1300 and DB1550 boards this timeout is slightly too short and causes transactions to the WM8731 codec to be falsely flagged as failed. The timeout itself is necessary since transactions to non-existant slaves never set this bit in the first place (and cause i2cdetect to hang). With this change the WM8731 codec on the DB1300/DB1550 boards is correctly detected and initialized.

The actual idle/unidle of the I2C hardware should not happen until the runtime PM callbacks are called. Therefore, change omap_i2c_[un]idle() functions to only be called from the runtime PM callbacks (when usage count transitions to/from zero.) Also, the runtime PM core does usage counting and replaces functionality currently managed by the dev->idle flag. Remove usage of dev->idle in favor of using runtime PM, and checking status using pm_runtime_suspended(). Signed-off-by: Kevin Hilman <khilman@ti.com>

However, you will probe the same 0x40 ID on an OMAP3530. So this patch changes the name to reflect that. It also clarifies that the original name OMAP_I2C_REV_2 is referring to some ancient OMAP1 revision number, not to be confused with the IP revisions this patch series introduces. Similarly the term "rev" is used in the ancient OMAP1 ISR, the term is changed to use omap1 instead.

| * | | | I2C: OMAP2+: Solve array bounds overflow error on i2c idleAndy Green2011-10-291-1/+1

Prior to this patch on OMAP3530 the driver wrongly interprets the I2C peripheral unit's own reported revision as meaning it is running on an IP V2 device and must use the extended registers. In fact OMAP3530 is IP V1 with the smaller register set, the reason for the confusion is that the hardware does in fact report having the same IP revision index as is found on an OMAP4430, which really is IP V2 and has the extended registers. This corrects the test for which registers to use so that it decides using hwmod knowledge found in the platform_data.
