Pull ARM changes from Russell King:
- Perf updates from Will Deacon:
- Support for Qualcomm Krait processors (run perf on your phone!)
- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.- SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan
- Support for Cortex-A12 CPU
- Align support for ARMv6 with ARMv7 so they can cooperate better in a
single zImage.- Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.
- Removal of IRQ_DISABLED from various ARM files
- Improved efficiency of virt_to_page() for single zImage
- Patch from Ulf Hansson to permit runtime PM callbacks to be available for
AMBA devices for suspend/resume as well.- Finally kill asm/system.h on ARM.

The SDHCI unit used on the Armada 380 and 385 Marvell SoC is similar
to the PXAv3 unit. The only difference is that on Armada 38x, the
PXAv3 unit accesses memory through MBus windows which must be
configured prior to using the device. Without this, DMA would not
work.In order to achieve this, the sdhci-pxav3 driver is extended with an
additional compatible string "marvell,armada-380-sdhci". When this
compatible string is used, the MBus windows are initialized in a way
that is identical to what all other DMA-capable drivers for Marvell
EBU platforms do.Signed-off-by: Marcin Wojtas

When the host->tuning_count is zero it means that the retuning is
disabled. This is checked on the first run of sdhci_execute_tuning()
by the if statement below:if (!(host->flags & SDHCI_NEEDS_RETUNING) && host->tuning_count &&
(host->tuning_mode == SDHCI_TUNING_MODE_1)) {So only when tuning_count is non-zero it will set the host flag
SDHCI_USING_RETUNING_TIMER. The else statement is only for re-programming
the timer, which means that flag must be set. Because that is not checked
the else statement is executed in the first run when tuning_count is zero.This was seen on a host controller which indicated SDHCI_TUNING_MODE_1 (0)
and tuning_count being zero. Suspect that (one of) these registers is not
properly set.Signed-off-by: Arend van Spriel

If the SDHCI irq is shared with another device then the interrupt

Add ACPI HID 80860F16 as a host controller for a SD card.
Signed-off-by: Adrian Hunter
Signed-off-by: Chris Ball -
Some 80860F14 devices do not support card detect and must rely
completely on GPIO. Presently the card detect GPIO is used
only to wake-up from runtime suspend. Change to using
mmc_gpioid_request_cd() which will cause the SDHCI driver to
prefer the GPIO to the host controller's native card detect.Signed-off-by: Adrian Hunter

Add functions to request a CD GPIO using the GPIO descriptor API.
Note that the new request function is paired with mmc_gpiod_free_cd()

mmc_gpiod_request_cd_irq().Signed-off-by: Adrian Hunter

interrupt handler.Signed-off-by: Russell King
Signed-off-by: Chris Ball -
None of this code is currently used: there are no definitions of
struct sdhci_plat_data in arch/arm, neither are there any DT properties

sdhci-spear is unsafe should a probe fail or defer, since it overwrites
