Use the new display drivers for OMAP3 Overo board. The new OMAP display drivers were merged for 3.11, and we can now change the board files to use the new ones and phase out the old ones. Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs for the panels. This means that both panel devices cannot be probed at the same time. DT will handle this correctly, i.e. the DT data will contain the panel device only for the add-on board that is attached. However, for the board file we need a hackish solution: We parse the kernel boot command line, and see whether lcd43 or lcd35 is set as a default display, and add the given one. Or, if neither is given, default to lcd43. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2013-08-28ARM: OMAP: 4430SDP: remove picodlp device dataTomi Valkeinen
4430SDP board has an option for a PicoDLP mini-projector. PicoDLP cannot be used at the same time as the second LCD, and there are GPIOs that need to be set/unset when changing the used display. Managing that kind of board specific setup is not simple without board file callbacks. As only some 4430SDP boards actually have the PicoDLP installed, and 4430SDP boards are not that common in the first place, let's remove PicoDLP data from the board file.

2013-08-27msm_serial: Switch clock consumer strings and simplify codeStephen Boyd
In downstream kernel we've standardized the clock consumer names that MSM device drivers use. Replace the uart specific clock names in this driver with the more standard 'core' and 'iface' names. Also simplify the code by assuming that clk_prepare_enable and clk_disable_unprepare() will properly check for NULL pointers (it will because MSM uses the common clock framework).

2013-08-27usb: musb: am335x: add second port to beagle boneSebastian Andrzej Siewior
So I assumed that Beagle bone has only one USB port in host mode because the micro USB connector had an USB-UART there. I was wrong a little. The second port runs on host mode, but the micro USB plug is connected to an internal HUB with two ports: one to the USB-UART and one to musb instance one. For that reason, this patch enables both ports: the primary in device mode only and the second in host mode only.

2013-08-27usb: musb: am335x-evm: Do not remove the session bit HOST-only modeSebastian Andrzej Siewior
This is what I observe: On the first connect, the musb starts with DEVCTL.Session set. On disconnect, musb_core calls try_idle. That functions removes the Session bit signalizing that the session is over (something that only in OTG is required). A new device, that is plugged, is no longer recognized. I've setup a timer and checked the DEVCTL register and I haven't seen a change in VBus and I saw the B-Device bit set. After setting the IDDIG into A mode and forcing the device to behave like a A device, I didn't see a change. Neither VBUS goes to 0b11 nor does a session start request comes. In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the OTG_STATE_A_WAIT_BCON state while not in OTG mode. Since the second port hast a standard A plug the patch changes the port to run in host mode only and skips the timer which would remove DEVCTL.Session so we can reconnect to another device later.

2013-08-27usb: usb: dsps: update code according to the binding documentSebastian Andrzej Siewior
This relfects the code and dts requires changes due to recent .dts binding updates: - use mg prefix for the Metor Graphics specific attributes - use power in mA not in mA/2 as specifed in the USB2.0 specification - remove the child node for USB. This is driver specific on won't be reflected in the device tree - use the "mentor" prefix instead of "mg". - use "dr_mode" istead of "mg,port-mode" for the port mode. The former is used by a few other drivers.

2013-08-27usb: musb: dsps fix the typo in reg-names of the dma nodeSebastian Andrzej Siewior
I forgot to separete the different names in the reg-names property. This didn't cause anything to fail because the driver does not use the names and simply relies on the order of the memory offsets in reg. This patch fixes this in case it is used later.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc fixes from Ben Herrenschmidt: "Here are 3 bug fixes that should probably go into 3.11 since I'm also tagging them for stable. Once fixes our old /proc/powerpc/lparcfg file which provides partition informations when running under our hypervisor and also acts as a user-triggerable Oops when hot :-( The other two respectively are a one liner to fix a HVSI protocol handshake problem causing the console to fail to show up on a bunch of machines until we reach userspace, which I deem annoying enough to warrant going to stable, and a nasty gcc miscompile causing us to pass virtual instead of physical addresses to the firmware under some circumstances" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/hvsi: Increase handshake timeout from 200ms to 400ms. powerpc: Work around gcc miscompilation of __pa() on 64-bit powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor
2013-08-27powerpc: Work around gcc miscompilation of __pa() on 64-bitPaul Mackerras
On 64-bit, __pa(&static_var) gets miscompiled by recent versions of gcc as something like: addis 3,2,.LANCHOR1+4611686018427387904@toc@ha addi 3,3,.LANCHOR1+4611686018427387904@toc@l This ends up effectively ignoring the offset, since its bottom 32 bits are zero, and means that the result of __pa() still has 0xC in the top nibble. This happens with gcc 4.8.1, at least. To work around this, for 64-bit we make __pa() use an AND operator, and for symmetry, we make __va() use an OR operator. Using an AND operator rather than a subtraction ends up with slightly shorter code since it can be done with a single clrldi instruction, whereas it takes three instructions to form the constant (-PAGE_OFFSET) and add it on. (Note that MEMORY_START is always 0 on 64-bit.) CC: <stable@vger.kernel.org> Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-27powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisorBenjamin Herrenschmidt
/proc/powerpc/lparcfg is an ancient facility (though still actively used) which allows access to some informations relative to the partition when running underneath a PAPR compliant hypervisor. It makes no sense on non-pseries machines. However, currently, not only can it be created on these if the kernel has pseries support, but accessing it on such a machine will crash due to trying to do hypervisor calls. In fact, it should also not do HV calls on older pseries that didn't have an hypervisor either. Finally, it has the plumbing to be a module but is a "bool" Kconfig option. This fixes the whole lot by turning it into a machine_device_initcall that is only created on pseries, and adding the necessary hypervisor check before calling the H_GET_EM_PARMS hypercall CC: <stable@vger.kernel.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2013-08-26x86/ioapic: Check attr against the previous setting when programmed more ↵Liu Ping Fan
than once When programming ioapic pinX more than once, current code does not check whether the later attr (trigger & polarity) is the same as the former or not. This causes broken semantics which can be observed in a qemu q35 machine, where ioapic's ioredtbl[x] can never be set as low-active, even if the hpet driver registered it. And hpet driver may share a high-level active IRQ line with other devices. So in qemu, when hpet-dev asserts low-level as kernel expects, the kernel has no response. With this patch, we can observe an ioredtbl[x] set as low-active for hpet. Fix it by reporting -EBUSY to the caller, when attr is different.

2013-08-26ppc: kvm: use anon_inode_getfd() with O_CLOEXEC flagYann Droneaud
KVM uses anon_inode_get() to allocate file descriptors as part of some of its ioctls. But those ioctls are lacking a flag argument allowing userspace to choose options for the newly opened file descriptor. In such case it's advised to use O_CLOEXEC by default so that userspace is allowed to choose, without race, if the file descriptor is going to be inherited across exec(). This patch set O_CLOEXEC flag on all file descriptors created with anon_inode_getfd() to not leak file descriptors across exec().

2013-08-26mips/kvm: Cleanup .push/.pop directives in kvm_locore.SDavid Daney
There are: .set push .set noreorder .set noat . . . .set pop Sequences all over the place in this file, but in some places the final ".set pop" is erroneously converted to ".set push", so none of these really do what they appear to. Clean up the whole mess by moving ".set noreorder", ".set noat" to the top, and get rid of everything else. Generated object code is unchanged.
