A recent "make driver conform to spec" change broke on deployed hardware. Make new behavior optional, rather than default, turning it on only for specific embedded platforms that need this. Everybody else runs in the famous "non conformant but working" mode. 2) pata_cmd64x, pata_legacy cleanups 3) new Intel SATA PCI IDs 4) misc minor vendor feature additions * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: pata_cmd64x: implement sff_irq_check() method pata_cmd64x: implement sff_irq_clear() method pata_cmd64x: use interrupt status from MRDMODE register pata_cmd64x: turn string of *if* statements into *switch* drivers/ata/pata_mpc52xx.c: clean up error handling code ahci_platform: add STRICT_AHCI platform type ahci: move AHCI_HFLAGS() macro to ahci.h ahci: add AHCI_HFLAG_DELAY_ENGINE host flag sata_fsl: add support for interrupt coalsecing feature ata/pata_arasan_cf: Add Hibernation support pata_legacy: correctly mask recovery field for HT6560B ata_piix: IDE-mode SATA patch for Intel Lynx Point DeviceIDs ahci: AHCI-mode SATA patch for Intel Lynx Point DeviceIDs

| * pata_cmd64x: implement sff_irq_clear() methodSergei Shtylyov2012-03-131-16/+15
| | | | | | | | | | | | | | | | | | | | Convert the driver's two bmdma_stop() methods into sff_irq_clear() methods -- they shouldn't have been bothering with clearing interrupts from the very start; the driver will now use the standard bmdma_stop() method implementation (where appropriate).

| * pata_cmd64x: use interrupt status from MRDMODE registerSergei Shtylyov2012-03-131-17/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Start using faster version of the bmdma_stop() method for the PCI0646U and newer chips that have the duplicate interrupt status bits in the I/O mapped MRDMODE register. Use the old, slow bmdma_stop() method on the older chips, taking into account that the interrupt bits are not coupled to DMA and that's enough to read the register to clear the interrupt (on the older chips). Determine what method to use at the driver load time. Fix kernel-doc of the bmdma_stop() methods, while at it.

While at it, somewhat clarify the comments there... Increment the driver version, accounting for the patches that neglected to do this in the past.

| * drivers/ata/pata_mpc52xx.c: clean up error handling codeJulia Lawall2012-03-131-29/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes a number of changes with respect to the error-handling code: * Remove cleanup calls for the devm functions in both the error handling code and the remove function. This cleanup is done automatically. * The previous change simplifies the cleanup code at the end of the function such that there is nothing to do on the failure of the call to devm_ioremap. So it is changed to just return directly. * There is no need for the ifs in the cleanup code at the end of the function, because in each case the cleanup needed is statically known. Drop the ifs, add new err labels, and drop the initializations of the tested variables to NULL. * Change the call to request_irq to a call to devm_request_irq, so that it is cleaned up on exit. * Cause the return value of devm_request_irq to go into the returned variable rv rather than the unused variable ret. Drop ret. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| * ahci: add AHCI_HFLAG_DELAY_ENGINE host flagBrian Norris2012-03-132-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commit was intended to fix problems with specific AHCI controller(s) that would become bricks if the AHCI specification was not followed strictly (that is, if ahci_start_engine() was called while the controller was in the wrong state): commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7 ahci: start engine only during soft/hard resets However, some devices currently have issues with that fix, so we must implement a flag that delays the ahci_start_engine() call only for specific controllers. This commit simply introduces the flag, without enabling it in any driver. Note that even when AHCI_HFLAG_DELAY_ENGINE is not enabled, this patch does not constitue a full revert to commit 7faa33da; there is still a change in behavior to the ahci_port_suspend() failure path.

| | * | | | Input: add Synaptics USB device driverJan Steinhoff2012-02-035-0/+607
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a driver for Synaptics USB touchpad or pointing stick devices. These USB devices emulate an USB mouse by default, so one can also use the usbhid driver. However, in combination with special user space drivers this kernel driver allows one to customize the behaviour of the device. An extended version of this driver with support for the cPad background display can be found at <http://jan-steinhoff.de/linux/synaptics-usb.html>.

| | * | | | Input: add infrastructure for selecting clockid for event time stampsJohn Stultz2012-02-033-4/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted by Arve and others, since wall time can jump backwards, it is difficult to use for input because one cannot determine if one event occurred before another or for how long a key was pressed. However, the timestamp field is part of the kernel ABI, and cannot be changed without possibly breaking existing users. This patch adds a new IOCTL that allows a clockid to be set in the evdev_client struct that will specify which time base to use for event timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME). For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but in the future we could support other clockids if appropriate. The default remains CLOCK_REALTIME, so we don't change the ABI.
