| | * HID: hid_reset_resume() needs to be defined only when CONFIG_PM is setJiri Kosina2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no point of having hid_reset_resume() when CONFIG_PM is not set, and even the corresponding .reset_resume pointer in hid_driver struct is properly ifdefed. Move the definition into the ifdef CONFIG_PM part of the source to avoid drivers/hid/usbhid/hid-core.c:1337: warning: 'hid_reset_resume' defined but not used Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| | * HID: fix USB HID devices after STD with autosuspendOliver Neukum2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug caused by reset_resume not changing the internal status flags for a device that is resumed via reset_resume. To do so the reset handlers, which correctly assume that a device is awake, can no longer do all the work of reset_resume handling.

| | * HID: autosuspend support for USB HIDOliver Neukum2009-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses the USB busy mechanism for aggessive autosuspend of USB HID devices. It autosuspends all opened devices supporting remote wakeup after a timeout unless - output is being done to the device - a key is being held down (remote wakeup isn't triggered upon key release) - LED(s) are lit - hiddev is opened As in the current driver closed devices will be autosuspended even if they don't support remote wakeup. The patch is quite large because output to devices is done in hard interrupt context meaning a lot a queuing and locking had to be touched. The LED stuff has been solved by means of a simple counter. Additions to the generic HID code could be avoided. In addition it now covers hidraw. It contains an embryonic version of an API to let the generic HID code tell the lower levels which capabilities with respect to power management are needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removal was scheduled and there is no problem with later distros to adapt for the new bus, thanks to aliases. module-init-tools map files are deprecated nowadays, so that the patch which introduced hid ones into the m-i-t won't be accepted and hence there is no reason for leaving compat stuff in.

| * | HID: fix race between usb_register_dev() and hiddev_open()Oliver Neukum2009-03-30

We need a lock usb_open() also takes in the right order and that leaves only one option, BKL. I don't like it but I see no alternative. Once the usb_open() implements something better than lock_kernel(), we could also do so. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hid quirks were converted to specialized driver, the HID_QUIRK_IGNORE has been moved completely, as the hid_ignore_list[] has been moved into the generic code. However userspace already got used to the possibility that modprobing usbhid with 'quirks=vid:pid:0x4' makes the device ignored by usbhid driver. So keep this quirk flag in place for backwards compatibility. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

This is very useful if you want to use the DMA controller in combination with a sound device which uses cyclic buffers. Using a DMA channel for cyclic DMA will disable the possibility to use it as a normal DMA engine until the user calls the cyclic free function on the DMA channel. Also a cyclic DMA list can not be prepared if the channel is already active.

| * | | | regulator: Support disabling of unused regulators by machinesMark Brown2009-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present it is not possible for machine constraints to disable regulators which have been left on when the system starts, for example as a result of fixed default configurations in hardware. This means that power may be wasted by these regulators if they are not in use. Provide intial support for this with a late_initcall which will disable any unused regulators if the machine has enabled this feature by calling regulator_has_full_constraints(). If this has not been called then print a warning to encourage users to fully specify their constraints so that we can change this to be the default behaviour in future.

| * | | | regulator: Don't increment use_count for boot_on regulatorsMark Brown2009-03-31

Any consumers which don't do disables which are not matched by enables are unable to share regulators - shared regulators are the common case so the API should facilitate them. Consumers that want to disable regulators that are enabled when they start have two options: - Do a regulator_enable() prior to the disable to bring the use count in sync with the hardware state; this will ensure that if the regulator was enabled by another driver then this consumer will play nicely with it. - Use regulator_force_disable(); this explicitly bypasses any checks done by the core and documents the inability of the driver to share the supply.

Buggy consumers could notice different bug symptoms. The main example would be refcounting bugs; also, any (out-of-tree) users of the experimental regulator_set_optimum_mode() stuff which don't call it when they're done using a regulator. This is a net minor codeshrink.
