2009-12-07Revert "pata_sis: Implement MWDMA for the UDMA 133 capable chips"Jeff Garzik
This reverts commit f20941f334d8fdb6b598658979709b4e94cd034b. Sergei Shtylyov notes "You call min() on uncomparables [in mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second argument will always "win" as a minimal one" Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related to mwdma_clip_to_pio(). The function can return values between 0 and 4 which obviously won't work well for the new code below for values >2 (i.e. resulting in out-of-bounds array access for the common-case of dev->pio_mode == XFER_PIO_4)." Bartlomiej Zolnierkiewicz also notes the patch is incomplete, failing to update MWDMA mode masks. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-12-06i2c: Refactor for_each callbacksJean Delvare
Functions i2c_do_add_adapter() and __attach_adapter() do essentially the same thing, differing only in how the parameters are passed. Same for i2c_do_add_adapter() and __detach_adapter(). Introduce wrappers to normalize the parameters, so that we do not have to duplicate the code. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <dbrownell@users.sourceforge.net>
2009-12-06i2c-i801: Retry on lost arbitrationJean Delvare
The Intel 82801 is sometimes used on systems with a BMC connected. The BMC can access the SMBus, resulting in lost arbitration for the 82801. We should let i2c-core retry transactions for us in this case. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2009-12-06i2c: Simplify i2c_detect_addressJean Delvare
The kind parameter of i2c_detect_address() always has value -1, so we can get rid of it. Next step is to update all i2c detect callback functions to get rid of this now useless parameter. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-12-06i2c: Drop probe, ignore and force module parametersJean Delvare
The legacy probe and force module parameters are obsolete now, the same can be achieved using the new_device sysfs interface, which is both more flexible and cheaper (it is implemented by i2c-core rather than replicated in every driver module.) The legacy ignore module parameters can be dropped as well. Ignoring can be done by instantiating a "dummy" device at the problematic address. This is the first step of a huge cleanup to i2c-core's i2c_detect function, i2c.h's I2C_CLIENT_INSMOD* macros, and all drivers that made use of them. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2009-12-06i2c: Bus drivers don't have to support I2C_M_REV_DIR_ADDRJean Delvare
I2C bus drivers don't have to support I2C_M_REV_DIR_ADDR. It is a deviation from the I2C specification, which only makes sense to implement when really needed. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Ben Dooks <ben-linux@fluff.org>
2009-12-06i2c: Prevent priority inversion on top of bus lockMika Kuoppala

2009-12-06i2c-powermac: Refactor i2c_powermac_smbus_xferJean Delvare
I wanted to add some error logging to the i2c-powermac driver, but found that it was very difficult due to the way the i2c_powermac_smbus_xfer function is organized. Refactor the code in this function so that each low-level function is only called once.

2009-12-06i2c-powermac: Reject unsupported I2C transactionsJean Delvare
The i2c-powermac driver doesn't support arbitrary multi-message I2C transactions, only SMBus ones. Make it clear by returning an error if a multi-message I2C transaction is attempted. This is better than only processing the first message, because most callers won't recover from the short transaction. Anyone wishing to issue multi-message transactions should use the SMBus API instead of the raw I2C API.

2009-12-06PM / Runtime: Ensure timer_expires is nonzero in pm_schedule_suspend()Rafael J. Wysocki
The runtime PM core code assumes that dev->power.timer_expires is nonzero when the timer is scheduled, but it may become zero incidentally in pm_schedule_suspend(). Prevent this from happening by bumping dev->power.timer_expires up to 1 if it's 0 before calling mod_timer(). Signed-off-by: Rafael J.

2009-12-06PM / Runtime: Use deferred_resume flag in pm_request_resumeAlan Stern
This patch (as1307) adds a small optimization to __pm_request_resume(). If the device is currently being suspended, there's no need to queue a work routine to resume it. Setting the deferred_resume flag will suffice. (There's also a minor improvement to the function's code layout: An unnecessary "else" is removed.) Also, the patch clarifies the usage of the deferred_resume flag. It is meaningful only while a suspend is in progress, so it should be cleared just before a suspend starts, not just after one ends.
