b71f6c40bb ixgbe: use link instead of I2C combined abstraction
Introduce ixgbe_link_operations struct with the following changes:

	read_i2c_combined		=> read_link
	read_i2c_combined_unlocked	=> read_link_unlocked
	write_i2c_combined		=> write_link
	write_i2c_combined_unlocked	=> write_link_unlocked

This will allow X550EM_a to override these methods for MDIO access
while X550EM_x provides methods to use I2C combined access. This
also adds a new structure, ixgbe_link_info, to hold information
about the link. Initially this is just method pointers and a bus
address.

The functions involved in combined I2C accesses were moved from
ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry
out the combined I2C accesses were left in ixgbe_phy.c because
they share some functions with other I2C methods.

v2 - set hw->link.ops in probe.
v3 - check ii->link_ops before setting it since we don't have it
for all devices.

3a62234680 drm/vc4: Use runtime autosuspend to avoid thrashing V3D power state.
The pm_runtime_put() we were using immediately released power on the
device, which meant that we were generally turning the device off and
on once per frame.  In many profiles I've looked at, that added up to
about 1% of CPU time, but this could get worse in the case of frequent
rendering and readback (as may happen in X rendering).  By keeping the
device on until we've been idle for a couple of frames, we drop the
overhead of runtime PM down to sub-.1%.

465e42180c pinctrl: qcom: Add msm8994 pinctrl driver
Initial pinctrl driver for QCOM msm8994 platforms.

In order to continue the initial board support for QCOM msm8994/msm8992
presented in patches from Jeremy McNicoll <jeremymc@redhat.com>, let's put
a proper pinctrl driver in place.

Currently, the DT for these platforms uses the msm8x74 pinctrl driver to
enable basic UART.  Beyond the first few pins the rest are different enough
to justify it's own driver.

Note: This driver is also used by QCOM's msm8992 platform as it's TLM block
is the same.

- Initial formatting and style was taken from the msm8x74 pinctrl driver
  added by Björn Andersson <bjorn.andersson@linaro.org>
- Data was then adjusted per QCOM MSM8994v2 documentation for Top Level
  Multiplexing
- Bindings documentation was based on qcom,msm8996-pinctrl.txt by
  Joonwoo Park <joonwoop@codeaurora.org> and then modified for msm8994

0c8c6ba00c pinctrl: sunxi: make bool drivers explicitly non-modular
None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get essentially the same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We do delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

efce21fc43 rtc: omap: prevent disabling of clock/module during suspend
If RTC is running from an internal clock source, the RTC module can't
be disabled; otherwise it stops ticking completely. Current suspend
handler implementation disables the clock/module unconditionally,
instead fix this by disabling the clock only if we are running on
external clock source, which is not affected by suspend.

The prevention of disabling the clock must be done via implementing
the runtime_pm handlers for the device, and returning an error code
from the runtime suspend handler; otherwise OMAP core PM will disable
the clocks for the driver.

The RTC functional clock is sourced by default from the clock derived
from the Peripheral PLL. In order to select source as external osc clk
the following changes needs to be done:
- Enable the RTC OSC (RTC_OSC_REG[4]OSC32K_GZ = 0)
- Enable the clock mux(RTC_OSC_REG[6]K32CLK_EN = 1)
- Select the external clock source (RTC_OSC_REG[3]32KCLK_SEL = 1)

d2cdf5dc58 pinctrl: cherryview: Prevent possible interrupt storm on resume
When the system is suspended to S3 the BIOS might re-initialize certain
GPIO pins back to their original state or it may re-program interrupt mask
of others. For example Acer TravelMate B116-M had BIOS bug where certain
GPIO pin (MF_ISH_GPIO_5) was programmed to trigger on high level, and the
pin state was high once the BIOS gave control to the OS on resume.

This triggers lots of messages like:

 irq 117, desc: ffff88017a61e600, depth: 1, count: 0, unhandled: 0
 ->handle_irq():  ffffffff8109b613, handle_bad_irq+0x0/0x1e0
 ->irq_data.chip(): ffffffffa0020180, chv_pinctrl_exit+0x2d84/0x12 [pinctrl_cherryview]
 ->action():           (null)
    IRQ_NOPROBE set

We reset the mask back to known state in chv_pinctrl_resume() but that is
called only after device interrupts have already been enabled.

Now, this particular issue was fixed by upgrading the BIOS to the latest
(v1.23) but not everybody upgrades their BIOSes so we fix it up in the
driver as well.

Prevent the possible interrupt storm by moving suspend and resume hooks to
be called at _noirq time instead. Since device interrupts are still
disabled we can restore the mask back to known state before interrupt storm
happens.

56211121c0 pinctrl: cherryview: Serialize register access in suspend/resume
If async suspend is enabled, the driver may access registers concurrently
with another instance which may fail because of the bug in Cherryview GPIO
hardware. Prevent this by taking the shared lock while accessing the
hardware in suspend and resume hooks.

300a18d13f ASoC: sun4i-codec: Add support for A31 board level audio routing
The A31 SoC's codec has various inputs, outputs and microphone bias
supplies. These can be routed on the board in different ways, such as:

  - HPCOM may be connected to have the headphone DC coupled.

  - Microphones all use the MBIAS main microphone supply or one mic may
    use the HBIAS supply, which supports headset detection and buttons.

  - Line Out may be routed to an audio jack, or an onboard speaker amp
    with power controls.

Add support for specifying the audio routes in the device tree.

ecd5cdb4fd ASoC: sun4i-codec: Add support for A31 analog microphone inputs
The A31 internal codec has 3 microphone outputs, of which MIC2 and MIC3
are muxed internally. The resulting two microphone inputs have separate
gain controls and mixer inputs.

The codec also has 2 microphone bias pins. HBIAS is specifically for the
headphone jack, which also supports headphone detection and control
buttons. These extra functions are not supported yet. The other, MBIAS,
is for all other analog microphones.

There is also mention of digital microphone support, but documentation
is scarce, and no hardware with it is available.

separate volume control.

This patch adds support for the playback path from the DAC to the Line

172ff5a22d clk: ti: make clk-dra7-atl explicitly non-modular
The Kconfig currently controlling compilation of this code is:

arch/arm/mach-omap2/Kconfig:config SOC_DRA7XX
arch/arm/mach-omap2/Kconfig:    bool "TI DRA7XX"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tags etc. since all that information
is already contained at the top of the file in the comments.

 "Fixes for amdgpu, radeon, intel, imx and virtio-gpu.

  This is a bit larger than I'd like, but I had some stuff I meant to

  this is really fixes for rc3 and rc4 in one go.

  There are a set of fixes for an oops we've been seeing around MST
  display unplug, along with more suspend/resume and shutdown fixes for
  amdgpu, one power management follow on fix for nouveau, and set of imx
  fixes, and a single virtio-gpu regression fix"
