2012-01-08ahci: platform support for suspend/resumeBrian Norris
Add platform hooks for custom suspend() and resume() functions. The generic suspend/resume code in drivers/ata/ahci_platform.c is adapted from the PCI version in drivers/ata/ahci.c. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2012-01-08ata: add ata port runtime PM callbacksLin Ming

2012-01-08[SCSI] sd: check runtime PM status in sd_shutdownLin Ming
sd_shutdown is called during reboot/poweroff. It may fail if parent device, for example, ata port, was runtime suspended. Fix it by checking runtime PM status of sd. Exit immediately if sd was runtime suspended already. Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2012-01-08[SCSI] check runtime PM status in system PMLin Ming
The only high-level SCSI driver that currently implements runtime PM is sd, and sd treats runtime suspend exactly the same as the SUSPEND and HIBERNATE stages of system sleep, but not the same as the FREEZE stage. Therefore, when entering the SUSPEND or HIBERNATE stages of system sleep, we can skip the callback to the driver if the device is already in runtime suspend. When entering the FREEZE stage, however, we should first issue a runtime resume. The overhead of doing this is negligible, because a suspended drive would be spun up during the THAW stage of hibernation anyway.

2012-01-08[SCSI] add flag to skip the runtime PM calls on the hostLin Ming
With previous change, now the ata port runtime suspend will happen as: disk suspend --> scsi target suspend --> scsi host suspend --> ata port suspend ata port(parent device) suspend need to schedule scsi EH which will resume scsi host(child device). Then the child device resume will in turn make parent device resume first. This is kind of recursive. This patch adds a new flag Scsi_Host::eh_noresume. ata port will set this flag to skip the runtime PM calls on scsi host.

2012-01-08ata: make ata port as parent device of scsi hostLin Ming
Currently, the device tree of ata port and scsi host looks as below, /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) This patch makes ata port as parent device of scsi host, then it becomes /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) With this change, the ata port runtime PM is easier. For example, the ata port runtime suspend will happen as, disk suspend --> scsi target suspend --> scsi host suspend --> ata port suspend.

2012-01-08ahci: start engine only during soft/hard resetsTejun Heo
This is another attempt at fixing the same problem that 270dac35c2 (libata: ahci_start_engine compliant to AHCI spec) tried to solve. Unfortunately, 270dac35c2 created regressions for a lot more common controllers and got reverted. This specific AHCI IP block becomes a brick if the DMA engine is started while DRQ is set. It is not possible to avoid the condition completely but the most common occurrence is caused by spurious use of ahci_start_engine() from ahci_start_port() during init sequence. DMA engine is started after both soft and hard resets and ahci_start_port() is always followed by resets, so there is no reason to start DMA engine from ahci_start_port(). This patch removes ahci_start_engine() invocation from ahci_start_port(). This change makes failure path of ahci_port_suspend() leave engine stopped without following resets. This is resolved by replacing ahci_start_port() call with ata_port_freeze() which forces resets afterwards, which is the better behavior anyway.

2012-01-08hid-input: add support for HID devices reporting Battery StrengthDaniel Nicoletti
I've sent an email earlier asking for help with a GetFeature code, and now I have a second patch on top of Jeremy's to provide the battery functionality for devices that support reporting it. If I understood correctly when talking to Jeremy he said his device never actually reported the status as an input event (sorry if I didn't understand it correctly), and after reading HID specs I believe it's really because it was meant to be probed, I have an Apple Keyboard and Magic Trackpad both bluetooth batteries operated, so using PacketLogger I saw that Mac OSX always ask the battery status using the so called GetFeature. What my patch does is basically: - store the report id that matches the battery_strength - setup the battery if 0x6.0x20 is found, even if that is reported as a feature (as it was meant to be but only the MagicTrackpad does) - when upower or someone access /sys/class/power_supply/hid-*/capacity it will probe the device and return it's status. It works great for both devices, but I have two concerns: - the report_features function has a duplicated code - it would be nice if it was possible for specific drivers to provide their own probe as there might be some strange devices... (but maybe it's already possible) I've talked to the upower dev and he fixed it to be able to show the right percentage.

2012-01-07r6040: fix typo in use of MCR0 register bitsCesar Eduardo Barros
Commit 4e16d6ebd65b4f2c4e3f780b4c5704beef64019c (r6040: define more MCR0 register bits) added #define values for MCR0 register bits and converted uses of hardcoded magic values to uses of these defines. However, one of the conversions looks suspicious: #define MCR0 0x00 /* Control register 0 */ +#define MCR0_RCVEN 0x0002 /* Receive enable */ +#define MCR0_XMTEN 0x1000 /* Transmission enable */ /* Init RDC private data */ - lp->mcr0 = 0x1002; + lp->mcr0 = MCR0_XMTEN | MCR0; I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes sense and matches the original values.
