| * GPIO: mvebu-gpio: Don't initialize the mask_cacheAndrew Lunn2012-10-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the SMP nature of some of the chips, which have per CPU registers, the driver does not use the generic irq_gc_mask_set_bit() & irq_gc_mask_clr_bit() functions, which only support a single register. The driver has its own implementation of these functions, which can pick the correct register depending on the CPU being used. The functions do however use the gc->mask_cache value. The call to irq_setup_generic_chip() was passing IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be initialized to the contents of some random register. This resulted in unexpected interrupts been delivered from random GPIO lines.

| * gpio/omap: fix off-mode bug: clear debounce settings on free/resetJon Hunter2012-10-271-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change was originally titled "gpio/omap: fix off-mode bug: clear debounce clock enable mask on free/reset". The title has been updated slightly to reflect (what should be) the final fix. When a GPIO is freed or shutdown, we need to ensure that any debounce settings are cleared and if the GPIO is the only GPIO in the bank that is currently using debounce, then disable the debounce clock as well to save power. Currently, the debounce settings are not cleared on a GPIO free or shutdown and so during a context restore on subsequent off-mode transition, the previous debounce values are restored from the shadow copies (bank->context.debounce*) leading to mismatch state between driver state and hardware state. This was discovered when board code was doing gpio_request_one() gpio_set_debounce() gpio_free() which was leaving the GPIO debounce settings in a confused state. If that GPIO bank is subsequently used with off-mode enabled, bogus state would be restored, leaving GPIO debounce enabled which then prevented the CORE powerdomain from transitioning. To fix this, introduce a new function called _clear_gpio_debounce() to clear any debounce settings when the GPIO is freed or shutdown. If this GPIO is the last debounce-enabled GPIO in the bank, the debounce will also be cut. Please note that we cannot use _gpio_dbck_disable() to disable the debounce clock because this has been specifically created for the gpio suspend path and is intended to shutdown the debounce clock while debounce is enabled. Special thanks to Kevin Hilman for root causing the bug. This fix is a collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and Santosh Shilimkar. Testing: - This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio, enabling debounce and then freeing the gpio and checking the register contents, the saved register context and the debounce clock state. - Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the ads7846 touchscreen in its board file using the above sequence, and so was failing off-mode tests in dynamic idle. Verified that off-mode tests are passing with this patch.

| * gpio: mvebu: correctly set the value in direction_output()Thomas Petazzoni2012-10-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The ->direction_output() operation of gpio_chip is supposed to set the direction to output but also to set the GPIO to an initial value. Unfortunately, this last part was not done until now, causing for example the LEDs to not be properly set to their default initial value. This patch fixes this by calling the mvebu_gpio_set() function from mvebu_gpio_direction_output() before configuring the GPIO as an output GPIO.

It has been successfully tested on Dove and Armada XP at the moment. Compared to the plat-orion driver, this new driver has the following added benefits: *) Support for Armada 370 and Armada XP *) It is integrated with the mvebu pinctrl driver so that GPIO pins are properly muxed, and the GPIO driver knows which GPIO pins are output-only or input-only. *) Properly placed in drivers/gpio *) More extensible mechanism to support platform differences. The plat-orion driver uses a simple mask-offset DT property, which works fine for Discovery MV78200 but not for Armada XP. The new driver uses different compatible strings to identify the different variants of the GPIO controllers.

This series contain: - A major tree renaming patch series: now, drivers are organized internally by their used bus, instead of by V4L2 and/or DVB API, providing a cleaner driver location for hybrid drivers that implement both APIs, and allowing to cleanup the Kconfig items and make them more intuitive for the end user; - Media Kernel developers are typically very lazy with their duties of keeping the MAINTAINERS entries for their drivers updated. As now the tree is more organized, we're doing an effort to add/update those entries for the drivers that aren't currently orphan; - Several DVB USB drivers got moved to a new DVB USB v2 core; the new core fixes several bugs (as the existing one that got bitroted). Now, suspend/resume finally started to work fine (at least with some devices - we should expect more work with regards to it); - added multistream support for DVB-T2, and unified the API for DVB-S2 and ISDB-S. Backward binary support is preserved; - as usual, a few new drivers, some V4L2 core improvements and lots of drivers improvements and fixes. There are some points to notice on this series: 1) you should expect a trivial merge conflict on your tree, with the removal of Documentation/feature-removal-schedule.txt: this series would be adding two additional entries there. I opted to not rebase it due to this recent change; 2) With regards to the PCTV 520e udev-related breakage, I opted to fix it in a way that the patches can be backported to 3.5 even without your firmware fix patch. This way, Greg doesn't need to rush backporting your patch (as there are still the firmware cache and firmware path customization issues to be addressed there). I'll send later a patch (likely after the end of the merge window) reverting the rest of the DRX-K async firmware request, fully restoring its original behaviour to allow media drivers to initialize everything serialized as before for 3.7 and upper. 3) I'm planning to work on this weekend to test the DMABUF patches for V4L2. The patches are on my queue for several Kernel cycles, but, up to now, there is/was no way to test the series locally. I have some concerns about this particular changeset with regards to security issues, and with regards to the replacement of the old VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to GPU drivers change. The Overlay API allows direct PCI2PCI transfers from a media capture card into the GPU framebuffer, but its API is crappy. Also, the only existing X11 driver that implements it requires a XV extension that is not available anymore on modern drivers. The DMABUF can do the same thing, but with it is promising to be a properly-designed API. If I can successfully test this series and be happy with it, I should be asking you to pull them next week." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (717 commits) em28xx: regression fix: use DRX-K sync firmware requests on em28xx drxk: allow loading firmware synchrousnously em28xx: Make all em28xx extensions to be initialized asynchronously [media] tda18271: properly report read errors in tda18271_get_id [media] tda18271: delay IR & RF calibration until init() if delay_cal is set [media] MAINTAINERS: add Michael Krufky as tda827x maintainer [media] MAINTAINERS: add Michael Krufky as tda8290 maintainer [media] MAINTAINERS: add Michael Krufky as cxusb maintainer [media] MAINTAINERS: add Michael Krufky as lg2160 maintainer [media] MAINTAINERS: add Michael Krufky as lgdt3305 maintainer [media] MAINTAINERS: add Michael Krufky as mxl111sf maintainer [media] MAINTAINERS: add Michael Krufky as mxl5007t maintainer [media] MAINTAINERS: add Michael Krufky as tda18271 maintainer [media] s5p-tv: Report only multi-plane capabilities in vidioc_querycap [media] s5p-mfc: Fix misplaced return statement in s5p_mfc_suspend() [media] exynos-gsc: Add missing static storage class specifiers [media] exynos-gsc: Remove <linux/version.h> header file inclusion [media] s5p-fimc: Fix incorrect condition in fimc_lite_reqbufs() [media] s5p-tv: Fix potential NULL pointer dereference error [media] s5k6aa: Fix possible NULL pointer dereference ...

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.

If another value comes to the register while the output pin is disabled, this new value will makae the older shift into the next register in the chain. This patch adds support for daisy-chaining the registers, using the regular SPI chip select mechanism to manage the output pin, and the registers-number dt property to set the number of chained registers.

Until the platform is switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just adds a might_sleep() call and would work without any issues. This will make it easy later to switch to common clk based implementation of clk driver from DaVinci specific driver.
