2012-09-14mfd: ab8500: Make ab8500_irq_get_virq() staticLee Jones
MFD core now takes care of HWIRQ <-> VIRQ mapping, so the helper ab8500_irq_get_virq() is no longer used by ab8500 subordinate devices to obtain a Linux wide Virtual IRQ. The AB8500 IRQ controller still uses it internally though, so we'll just hide it from the rest of the world by making it static instead.

2012-09-14gpio: gpio-ich: Share ownership of GPIO groupsJean Delvare
The ICH chips have their GPIO pins organized in 2 or 3 independent groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

2012-09-14mfd: core: Push irqdomain mapping out into devicesMark Brown
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

2012-09-11resources: Add register address resource typeMark Brown
Currently a bunch of I2C/SPI MFD drivers are using IORESOURCE_IO for register address ranges. Since this causes some confusion due to the primary use of this resource type for PCI/ISA I/O ports create a new resource type IORESOURCE_REG. Unfortunately the current resource types are specified as bitmasks and there are no free bitmasks even though they really shouldn't be used as such so we define the new type as IORESOURCE_IO | IORESOURCE_MEM. Benjamin Herrenschmidt and Russell King have both verified that none of the users in this series will have a problem with this, and no new code should be affected.

2012-09-11mfd: 88pm860x: Move _IO resources out of ioport_ioresourceMark Brown
The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.

Fix it by removing all the checks for iTCO_wdt to keep the same behavior as 3.4 kernel. https://bugzilla.kernel.org/show_bug.cgi?id=44991 Actually the same check could be removed for the gpio-ich in lpc_ich.c, but I'm not sure if it will cause problems.

2012-08-22mfd: Move tps65217 regulator plat data handling to regulatorAnilKumar Ch
Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

2012-08-16autofs4 - fix get_next_positive_subdir()Ian Kent
Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability.

2012-08-14drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter
eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

2012-08-14GPIO: gpio-pxa: fix building without CONFIG_OFArnd Bergmann
Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

2012-08-14drm/nouveau: disable copy engine on NVAFHenrik Rydberg
The copy engine exhibits random memory corruption in at least one case, the GeForce 320M (nv50, 0xaf) in the MacBookAir3,1. This patch omits creating the engine for the specific chipset, falling back to M2MF, which kills the symptoms.
