2012-09-14mfd: ab8500: Make ab8500_irq_get_virq() staticLee Jones1-17/+16
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 Delvare2-12/+96
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 Brown53-111/+122
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.

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.

There are many reports (including 2 of my machines) that iTCO_wdt watchdog driver fails to be initialized in 3.5 kernel with error message like: [ 5.265175] ACPI Warning: 0x00001060-0x0000107f SystemIO conflicts with Region \_SB_.PCI0.LPCB.TCOI 1 (20120320/utaddress-251) [ 5.265192] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver [ 5.265206] lpc_ich: Resource conflict(s) found affecting iTCO_wdt The root cause the iTCO_wdt driver in 3.4 probes the HW IO resource from LPC's PCI config space, while in 3.5 kernel it relies on lpc_ich driver for the probe, which adds a new acpi_check_resource_conflict() check, and give up the probe if there is any conflict with ACPI. 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 Ch2-102/+152
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.

2012-08-14drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter1-7/+7
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.

2012-08-13drm/i915: ensure i2c adapter is all set before adding itJani Nikula1-3/+4
i2c_add_adapter() may do i2c transfers on the bus to detect supported devices. Therefore the adapter needs to be all set before adding it. This was not the case for the bit-banging fallback, resulting in an oops if the device detection GMBUS transfers timed out. Fix the issue by calling i2c_add_adapter() only after intel_gpio_setup().

2012-08-13drm/radeon/kms: add MSAA texture support for r600-evergreenMarek Olšák3-2/+15
Most of the checking seems to be in place already. As you can see, log2(number of samples) resides in LAST_LEVEL. This is required for MSAA support (namely for depth-stencil resolve and blitting between MSAA resources).

2012-08-13drm/radeon: do not reenable crtc after moving vram start addressJerome Glisse3-76/+2
It seems we can not update the crtc scanout address. After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.
