2012-10-01Merge tag 'cleanup2' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc cleanups, part 2 from Olof Johansson: "A shorter cleanup branch submitted separately due to dependencies with some of the previous topics. Major thing here is that the Broadcom bcmring platform is removed. It's an SoC that's used on some stationary VoIP platforms, and is in desperate need of some cleanup. Broadcom came back and suggested that we just deprecate the platform for now, since they aren't going to spend the resources needed on cleaning it up, and there are no users of the platform directly from mainline." Fix some conflicts due to BCM2835 getting added next to the removed BCMRING, and removal of tegra files that had been converted to devicetree. * tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: Orion5x: ts78xx: Add IOMEM for virtual addresses.

Pull ARM soc general cleanups from Olof Johansson: "This is a large branch that contains a handful of different cleanups: - Fixing up the I/O space remapping on PCI on ARM. This is a series from Rob Herring that restructures how all pci devices allocate I/O space, and it's part of the work to allow multiplatform kernels. - A number of cleanup series for OMAP, moving and removing some headers, sparse irq rework and in general preparation for multiplatform. - Final removal of all non-DT boards for Tegra, it is now device-tree-only! - Removal of a stale platform, nxp4008. It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel. We have not been able to find anyone interested in keeping it around in the kernel. - Removal of the legacy dmaengine driver on tegra + A handful of other things that I haven't described above."

2012-09-17efifb: Skip DMI checks if the bootloader knows what it's doingMatthew Garrett
The majority of the DMI checks in efifb are for cases where the bootloader has provided invalid information. However, on some machines the overrides may do more harm than good due to configuration differences between machines with the same machine identifier. It turns out that it's possible for the bootloader to get the correct information on GOP-based systems, but we can't guarantee that the kernel's being booted with one that's been updated to do so. Add support for a capabilities flag that can be set by the bootloader, and skip the DMI checks in that case. Additionally, set this flag in the UEFI stub code.

2012-09-12ARM: OMAP2+: Prepare for irqs.h removalTony Lindgren
As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2012-08-23OMAPDSS: Fix SDI PLL lockingTomi Valkeinen
Commit f476ae9dab3234532d41d36beb4ba7be838fa786 (OMAPDSS: APPLY: Remove DISPC writes to manager's lcd parameters in interface) broke the SDI output, as it causes the SDI PLL locking to fail. LCLK and PCLK divisors are located in shadow registers, and we normally write them to DISPC registers when enabling the output. However, SDI uses pck-free as source clock for its PLL, and pck-free is affected by the divisors. And as we need the PLL before enabling the output, we need to write the divisors early. It seems just writing to the DISPC register is enough, and we don't need to care about the shadow register mechanism for pck-free. The exact reason for this is unknown.

2012-08-22fbcon: fix race condition between console lock and cursor timer (v1.1)Dave Airlie
So we've had a fair few reports of fbcon handover breakage between efi/vesafb and i915 surface recently, so I dedicated a couple of days to finding the problem. Essentially the last thing we saw was the conflicting framebuffer message and that was all. So after much tracing with direct netconsole writes (printks under console_lock not so useful), I think I found the race. Thread A (driver load) Thread B (timer thread) unbind_con_driver -> | bind_con_driver -> | vc->vc_sw->con_deinit -> | fbcon_deinit -> | console_lock() | | | | fbcon_flashcursor timer fires | console_lock() <- blocked for A | | fbcon_del_cursor_timer -> del_timer_sync (BOOM) Of course because all of this is under the console lock, we never see anything, also since we also just unbound the active console guess what we never see anything. Hopefully this fixes the problem for anyone seeing vesafb->kms driver handoff. v1.1: add comment suggestion from Alan. Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann <arnd@arndb.de>: "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

This reverts commit 9ea3c498962bc63748e92c31c874169ab0726324. 'data' is being allocated by devm_kzalloc(), is it's actually wrong to free() it in the error path, as it will be destroyed properly later.

If we accidentally pass an incorrect bpp value to pixel_to_pat(), it panics. This is pretty useless, as we generally have the various console locks held at that point, so nothing will be displayed, and there is no reason to make this a fatal event. Let's WARN instead.
