2013-05-28ARM: mvebu: Fix bug in coherency fabric low level init functionNadav Haklai1-5/+11
When adding CPU to the SMP group and enabling the coherency on this CPU we must protect the register access. The previous implementation claims to be atomic but doesn't provide any protection against parallel access to the coherency fabric control and configuration registers. This patch fixes this by using the ldrex and strex mechanism. This method should be used in all accesses to those registers.

2013-05-28ARM: Kirkwood: TS219: Fix crash by double PCIe instantiationAndrew Lunn1-10/+0
When creating the DT based boards-ts219.c the none DT ts219-setup.c was used as a template. This includes a lateinit() call to initialize the PCIe bus. The code makes use of machine_is_ts219() which is never true on DT, so a FIXME was added and the code left as is. This was unproblematic until b73690c8f8b5d: "ARM: Kirkwood: Support basic hotplug for PCI-E" which changes the way the PCIe bus is initialized. The non-DT ts219-setup.c now crashes during boot. The lateinit() call in the DT boards-ts219.c is being called, machine_is_ts219() is true and so the PCIe is initialized a second time. This patch removes the useless, and now clearly dangerous, code from boards-ts219.c, making ts219-setup.c work again.

2013-05-27ARM: ux500: Provide supplies for AUX1, AUX2 and AUX3Lee Jones1-0/+3
This patch fixes a bug introduced in the v3.10 merge window. The AB8500 External Regulator driver has recently landed upstream, which registers each of the 3 external regulators located on the AB8500. If these regulators are marked as 'always on', there is a potential for power-loss. If they're not and are seemingly unused the Regulator subsystem will attempt to disable them to save power. This causes an issue for AUX1, AUX2 and AUX3 as they obtain their power from EXT3. So we're specifying that here to prevent EXT3 from being powered down.

2013-05-27ARM: ux500: Only configure wake-up reasons on ux500 based platformsLee Jones1-0/+4
Multiplatform calls all enabled platforms' initcalls. In the ux500_idle_init() initcall we call into the DBx500-PRCMU which in turn executes some ux500 specific register reads/writes. When running on some !ux500 platforms this ends up causing a kernel Oops. This patch ensures the PRCMU call is only invoked when running on ux500 based platforms.

2013-05-22ARM: 7729/1: vfp: ensure VFP_arch is non-zero when VFP is not supportedWill Deacon1-1/+1
Commit d3f79584a8b5 ("ARM: cleanup undefined instruction entry code") improved the register scheduling when handling undefined instructions. A side effect of this is that r5 is now used as a temporary, whilst the VFP probing code relies on r5 containing a non-zero value when VFP is not supported. This patch fixes the VFP detection code so that we don't rely on the contents of r5. Without this patch, Linux dies loudly on CPUs without VFP support.

2013-05-22ARM: 7727/1: remove the .vm_mm value from gate_vmaSteven Capper1-1/+0
If one reads /proc/$PID/smaps, the mmap_sem belonging to the address space of the task being examined is locked for reading. All the pages of the vmas belonging to the task's address space are then walked with this lock held. If a gate_vma is present in the architecture, it too is examined by the fs/proc/task_mmu.c code. As gate_vma doesn't belong to the address space of the task though, its pages are not walked. A recent cleanup (commit f6604efe) of the gate_vma initialisation code set the vm_mm value to &init_mm. Unfortunately a non-NULL vm_mm value in the gate_vma will cause the task_mmu code to attempt to walk the pages of the gate_vma (with no mmap-sem lock held). If one enables Transparent Huge Page support and vm debugging, this will then cause OOPses as pmd_trans_huge_lock is called without mmap_sem being locked. This patch removes the .vm_mm value from gate_vma, restoring the original behaviour of the task_mmu code.

When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it failed to boot. The issues seems to be changing by enabling or disabling VT8550 platform. Having a quick look at dt_compat list, it seems to miss a NULL terminator, which means of_flat_dt_match will compat check will cross the boundary of dt_compat and fault at some point , which is what was happening in my case. Without this patch if we try to boot multi_v7_defconfig you might notice that some of the platforms might fault if they fall after vt8500 in machine-desc list.

2013-05-19ARM: OMAP2+: hwmod-data: UART IP needs software control to manage sidle modesSantosh Shilimkar4-1/+18
OMAP UART IP needs software control for slave idle modes based on functional state of the IP. i.e The IP slave idle settings should be set to 'noidle' when being used and then put back to 'smart_idle' when unused. Currently this is handled by the driver with function pointers implemented in platform code. This however breaks in case of device tree because of missing idle handling APIs. Previous patches in this series added a flag HWMOD_SWSUP_SIDLE_ACTIVE which takes care of the mentioned requirement. Hence add the flag for all UART IPs to take advantage of feature supported by framework. Subsequent patches removes the slave idle handling from driver code.

2013-05-19ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in activeRajendra Nayak2-1/+6
Some IPs (like UART) need the sidle mode to be controlled in SW only while they are active. Once they go inactive, they need the IP to be put back in HW control so they are also wakeup capable. The flag HWMOD_SWSUP_SIDLE takes care of IPs which need the sidle mode to be *always* controlled in SWSUP. We now have a need to control IPs sidle mode in SWSUP only while its active. So define a new flag 'HWMOD_SWSUP_SIDLE_ACT' to help the framework know about these new IP requirements.

2013-05-19ARM: OMAP2+: hwmod: Fix sidle programming in _enable_sysc()/_idle_sysc()Rajendra Nayak1-17/+25
_enable_sysc() and _idle_sysc() handle the midle mode programming correctly and program HWMOD_IDLEMODE_SMART or HWMOD_IDLEMODE_SMART_WKUP respectively for supported IPs (The ones which support hardware controlled midle modes) However the same programming logic is missing when it comes to sidle mode programming. Here they seem to just set HWMOD_IDLEMODE_SMART (Again for the ones which support hardware controlled sidle modes) This problem was hidden due to the fact that a call to _enable_wakeup() in those same functions would overwrite the idlemodes and program them correctly (to HWMOD_IDLEMODE_SMART_WKUP in the supported cases) So fix the sidlemode handling correctly in these functions and handle the _enable_wakeup() for SIDLEMODE supported IPs same as the way its handled for MIDLEMODE supported ones.

2013-05-19arm: mvebu: fix the 'ranges' property to handle PCIeThomas Petazzoni2-2/+4
Since 82a682676 ('ARM: dts: mvebu: Convert all the mvebu files to use the range property') all the device nodes of Armada 370/XP are under a common 'ranges' property that translates the device register addresses into their absolute address, thanks to the base address of the internal register space. However, beyond just the register areas, there are also PCIe I/O and memory regions, whose addresses should be properly translated. This patch fixes the Armada 370 and XP ranges property to take PCIe into account properly.

2013-05-19ARM: mvebu: select ARCH_REQUIRE_GPIOLIB for mvebu platformGregory CLEMENT1-0/+1
Initially ARCH_REQUIRE_GPIOLIB was part of Thomas Petazzoni series when he introduced the gpiolib support for mvebu: 93a59cf arm: mvebu: use GPIO support now that a driver is available This commit was written to be applied for the ARCH_MVEBU which was located in arch/arm/KConfig and was merged in 3.7. In the same time Rob Herring moved the ARCH_MVEBU block to arch/arm/mach-mvebu/Kconfig with this commit and also merged in 3.7: 387798b ARM: initial multiplatform support Unfortunately the ARCH_REQUIRE_GPIOLIB have been lost during this migration. This was not noticed until the v3.10-rc1, because mvebu as part of ARCH_MULTIPLATFORM was always selected with ARCH_VEXPRESS, and this architect selected ARCH_REQUIRE_GPIOLIB. Since the following commit from Arnd: "883a106 ARM: default machine descriptor for multiplatform", ARCH_VEXPRESS was then no more selected by default with ARCH_MVEBU and it made appeared the lack of ARCH_REQUIRE_GPIOLIB for mvebu. This commit added back the selection of ARCH_REQUIRE_GPIOLIB for ARCH_MVEBU. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull devm usage cleanup from Wolfram Sang: "Lately, I have been experimenting how to improve the devm interface to make writing device drivers easier and less error prone while also getting rid of its subtle issues. I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

2013-05-17ARM: AM33XX: Add missing .clkdm_name to clkdiv32k_ick clockVaibhav Hiremath1-3/+23
It is required to enable respective clock-domain before enabling any clock/module inside that clock-domain. During common-clock migration, .clkdm_name field got missed for "clkdiv32k_ick" clock, which leaves "clk_24mhz_clkdm" unused; so it will be disabled even if childs of this clock-domain is enabled, which keeps child modules in idle mode. This fixes the kernel crash observed on AM335xEVM-SK platform, where clkdiv32_ick clock is being used as a gpio debounce clock and since clkdiv32k_ick is in idle mode it leads to below crash - Crash Log: ========== [ 2.598347] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa1ac150 [ 2.606434] Internal error: : 1028 [#1] SMP ARM [ 2.611207] Modules linked in: [ 2.614449] CPU: 0 Not tainted (3.8.4-01382-g1f449cd-dirty #4) [ 2.620973] PC is at _set_gpio_debounce+0x60/0x104 [ 2.626025] LR is at clk_enable+0x30/0x3c Cc: stable@vger.kernel.org # v3.9 Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Cc: Rajendra Nayak <rnayak@ti.com> Acked-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
