2012-05-07ARM: OMAP3: clock data: add clockdomain for HDQ functional clockPaul Walmsley
Add the correct clockdomain for the HDQ functional clock. This is needed for the clock and hwmod PM code to work correctly. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: NeilBrown <neilb@suse.de>
2012-05-07ARM: OMAP3+: dpll: Configure autoidle mode only if it's supportedVaibhav Bedia
The current DPLL code enables and disables autoidle features without checking whether the autoidle register is available. Fix this by putting a check for the existence of the autoidle register in the DPLL data. With such a check in place, for DPLLs which do not support this feature, simply skipping the autoidle_reg entry in the DPLL data is sufficient.

2012-05-07ARM: OMAP4+: Add prm and cm base init function.R Sricharan
Instead of statically defining seperate arrays for every OMAP4+ archs, have a generic init function to populate the arrays. This avoids the need for creating new array for every arch added in the future that reuses the prm and cm registers read/write code.

2012-05-07ARM: OMAP3: clock data: treat all AM35x devices the sameKevin Hilman
The init for 3505/3517 specific clocks depends on the ordering of cpu_is checks, is error prone and confusing (there are 2 separate checks for cpu_is_omap3505()). Remove the 3505-specific checking since CK_3505 flag is not used, and treat all AM35x clocks the same. This means that the SGX clock (the only AM35x clkdev not currently flagged for 3505) will now be registered on 3505, but that is harmless. That can be cleaned up when the clkdev nodes are removed in favor of them being registered by hwmod.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: gadget: patches for v3.5 This pull request is quite big, but mainly because there's a giant rework of the s3c_hsotg.c driver to make it friendlier for other users. Samsung Exynos platforms use the DesignWare Core USB2 IP from Synopsys so it's a bit unfair to have the driver work for Samsung platforms only. In short, the big rework is in preparation to make the driver more reusable. Another big rework in this pull request came from Ido, where he's removing the redundant pointer for the endpoint descriptor from the controller driver's own endpoint representation. The same pointer is available through the generic struct usb_ep structure. Also on this pull request is the conversion of a few extra controller drivers to the new style registration, which allows multiple controllers to be available on the same platform and helps remove global pointers from those drivers. Together with those big changes, there's the usual fixes and cleanups to gadget drivers. Nothing major.

2012-05-06ARM: 7414/1: SMP: prevent use of the console when using idmap_pgdColin Cross
Commit 4e8ee7de227e3ab9a72040b448ad728c5428a042 (ARM: SMP: use idmap_pgd for mapping MMU enable during secondary booting) switched secondary boot to use idmap_pgd, which is initialized during early_initcall, instead of a page table initialized during __cpu_up. This causes idmap_pgd to contain the static mappings but be missing all dynamic mappings. If a console is registered that creates a dynamic mapping, the printk in secondary_start_kernel will trigger a data abort on the missing mapping before the exception handlers have been initialized, leading to a hang. Initial boot is not affected because no consoles have been registered, and resume is usually not affected because the offending console is suspended. Onlining a cpu with hotplug triggers the problem. A workaround is to the printk in secondary_start_kernel until after the page tables have been switched back to init_mm.

2012-05-05ARM: 7411/1: audit: fix treatment of saved ip register during syscall tracingWill Deacon
The ARM audit code incorrectly uses the saved application ip register value to infer syscall entry or exit. Additionally, the saved value will be clobbered if the current task is not being traced, which can lead to libc corruption if ip is live (apparently glibc uses it for the TLS pointer). This patch fixes the syscall tracing code so that the why parameter is used to infer the syscall direction and the saved ip is only updated if we know that we will be signalling a ptrace trap.

2012-05-05ARM: 7410/1: Add extra clobber registers for assembly in kernel_execveTim Bird
The inline assembly in kernel_execve() uses r8 and r9. Since this code sequence does not return, it usually doesn't matter if the register clobber list is accurate. However, I saw a case where a particular version of gcc used r8 as an intermediate for the value eventually passed to r9. Because r8 is used in the inline assembly, and not mentioned in the clobber list, r9 was set to an incorrect value. This resulted in a kernel panic on execution of the first user-space program in the system. r9 is used in ret_to_user as the thread_info pointer, and if it's wrong, bad things happen.

2012-05-04ARM: OMAP: Revert "ARM: OMAP: ctrl: Fix CONTROL_DSIPHY register fields"Archit Taneja
This reverts commit 46f8c3c7e95c0d30d95911e7975ddc4f93b3e237. The commit above swapped the DSI1_PPID and DSI2_PPID register fields in CONTROL_DSIPHY to be in sync with the newer public OMAP TRMs(after version V). With this commit, contention errors were reported on DSI lanes some OMAP4 SDPs. After probing the DSI lanes on OMAP4 SDP, it was seen that setting bits in the DSI2_PPID field was pulling up voltage on DSI1 lanes, and DSI1_PPID field was pulling up voltage on DSI2 lanes. This proves that the current version of OMAP4 TRM is incorrect, swap the position of register fields according to the older TRM versions as they were correct.

Commit 384ebe1c2849160d040df3e68634ec506f13d9ff, "gpio/omap: Add DT support to GPIO driver", introduced dynamic IRQ numbering of OMAP GPIO interrupts, breaking all IH_GPIO_BASE based IRQ number calculations.

2012-05-04ARM: 7389/2: plat-versatile: modernize FPGA IRQ controllerLinus Walleij
This does two things to the FPGA IRQ controller in the versatile family: - Convert to MULTI_IRQ_HANDLER so we can drop the entry macro from the Integrator. The C IRQ handler was inspired from arch/arm/common/vic.c, recent bug discovered in this handler was accounted for. - Convert to using IRQ domains so we can get rid of the NO_IRQ mess and proceed with device tree and such stuff. As part of the exercise, bump all the low IRQ numbers on the Integrator PIC to start from 1 rather than 0, since IRQ 0 is now NO_IRQ. The Linux IRQ numbers are thus entirely decoupled from the hardware IRQ numbers in this controller. I was unable to split this patch. The main reason is the half-done conversion to device tree in Versatile. Tested on Integrator/AP and Integrator/CP.
