2016-01-05regmap: irq: add support for configuration of trigger typeLaxman Dewangan
Some of devices supports the trigger level for interrupt like rising/falling edge specially for GPIOs. The interrupt support of such devices may have uses the generic regmap irq framework for implementation. Add support to configure the trigger type device interrupt register via regmap-irq framework. The regmap-irq framework configures the trigger register only if the details of trigger type registers are provided.

2016-01-05mmc: tegra: use correct accessor for misc ctrl registerLucas Stach
The misc control register is 32bit wide, the used readw/writew accessors only mainipulate the low 16bit of this register. It currently doesn't matter as all the bit changed are located in the lower half, but together with the u32 variable used to hold the contents of the register it is seriously confusing. Switch to 32bit accessors to avoid any future breakage. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2016-01-05mmc: tegra: enable UHS-I modesLucas Stach
Keep the quirk bits, as Tegra30 and Tegra114 host have different levels of support for UHS-I modes and so need different spare bits to be set, but change the logic to be positive. Tegra210 needs a different tuning sequence than Tegra30+. Disable UHS modes until support for this is properly added.

2016-01-05of/unittest: Show broken behaviour in the platform busGrant Likely
Add a single resource to the test bus device to exercise the platform bus code a little more. This isn't strictly a devicetree test, but it is a corner case that the devicetree runs into. Until we've got platform device unittests, it can live here. It doesn't need to be an explicit text because the kernel will oops when it is wrong.

2016-01-05ACPI / video: driver must be registered before checking for keypressesAdrien Schildknecht
acpi_video_handles_brightness_key_presses() may use an uninitialized mutex. The error has been reported by lockdep: DEBUG_LOCKS_WARN_ON(l->magic != l). The function assumes that the video driver has been registered before being called. As explained in the comment of acpi_video_init(), the registration of the video class may be defered and thus may not take place in the init function of the module. Use completion mechanisms to make sure that acpi_video_handles_brightness_key_presses() wait for the completion of acpi_video_register() before using the mutex. Also get rid of register_count since task completion can replace it.
