Reserved for ACPI actually means that in such case the GPIO hardware will not update the interrupt status register (GPI_IS) even if the pin is configured to trigger an interrupt. It will update GPI_GPE_STS instead and does not trigger an interrupt. Allow using such pins as GPIOs, only prevent their usage as interrupts. We also rename function intel_pad_reserved_for_acpi() to be intel_pad_acpi_mode() which reflects the actual meaning better.

On Intel Broxton the GPIO hardware consists of several chips that all share the parent interrupt. It is not possible to handle this by setting chained handler for each chip (as they will overwrite each other). To overcome this we need to request the interrupt using devm_request_irq() and pass IRQF_SHARED with the flags.

2015-10-27gpio: generic: Revert to old error handling in bgpio_mapGuenter Roeck
Returning an error instead of NULL in bgpio_map if platform_get_resource_byname does not find a resource was introduced with commit cf3f2a2c8bae ("gpio: generic: improve error handling in bgpio_map"). This results in several qemu runtime failures with default and non-default configurations, if attempts are made to boot from mmcblk0. Examples for failures with multi_v7_defconfig are Machine: vexpress-a9 dtb: vexpress-v2p-ca9 Machine: vexpress-a15 dtb: vexpress-v2p-ca15-tc1 Crash: VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) Looking into the code, always returning an error if bgpio_map fails does not appear to make much sense, since the code in bgpio_setup_io specifically supports some of the resources to be NULL.

2015-10-27drivers/pinctrl: Add the concept of an "init" stateDouglas Anderson
For pinctrl the "default" state is applied to pins before the driver's probe function is called. This is normally a sensible thing to do, but in some cases can cause problems. That's because the pins will change state before the driver is given a chance to program how those pins should behave. As an example you might have a regulator that is controlled by a PWM (output high = high voltage, output low = low voltage). The firmware might leave this pin as driven high. If we allow the driver core to reconfigure this pin as a PWM pin before the PWM's probe function runs then you might end up running at too low of a voltage while we probe. Let's introudce a new "init" state. If this is defined we'll set pinctrl to this state before probe and then "default" after probe (unless the driver explicitly changed states already). An alternative idea that was thought of was to use the pre-existing "sleep" or "idle" states and add a boolean property that we should start in that mode. This was not done because the "init" state is needed for correctness and those other states are only present (and only transitioned in to and out of) when (optional) power management is enabled. Changes in v3: - Moved declarations to pinctrl/devinfo.h - Fixed author/SoB Changes in v2: - Added comment to pinctrl_init_done() as per Linus W.

2015-10-27mmc: pwrseq: Use highest priority for eMMC restart handlerJavier Martinez Canillas
The pwrseq_emmc driver does a eMMC card reset before a system reboot to allow broken or limited ROM boot-loaders (that don't have an eMMC reset logic) to be able to read the second stage from the eMMC. But this has to be called before a system reboot handler and while most of them use the priority 128, there are other restart handlers (such as the syscon-reboot one) that use a higher priority. So, use the highest priority to make sure that the eMMC hw is reset before a system reboot.

2015-10-27pinctrl: uniphier: set input-enable before pin-muxingMasahiro Yamada
While IECTRL is disabled, input signals are pulled-down internally. If pin-muxing is set up first, glitch signals (Low to High transition) might be input to hardware blocks. Bad case scenario: [1] The hardware block is already running before pinctrl is handled. (the reset is de-asserted by default or by a firmware, for example) [2] The pin-muxing is set up. The input signals to hardware block are pulled-down by the chip-internal biasing. [3] The pins are input-enabled. The signals from the board reach the hardware block. Actually, one invalid character is input to the UART blocks for such SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the power on reset. To avoid such problems, pins should be input-enabled before muxing.
