51a831a772 Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued
Chris Wilson needs the new drm_driver->release callback to make sure
the shiny new dma-buf testcases don't oops the driver on unload.

7ff89ca213 drm/i915: Move most cdclk/rawclk related code to intel_cdclk.c
Let's try to shrink intel_display.c a bit by moving the cdclk/rawclk
stuff to a new file. It's all reasonably self contained so we don't
even have to add that many non-static symbols.

We'll also take the opportunity to shuffle around the functions a bit
to get things in a more consistent order based on the platform.

v2: Add kernel-docs (Ander)
v3: Deal with IS_GEN9_BC()
v4: Deal with i945gm_get_cdclk()

1db7afa491 drm/msm: drop qcom,chipid
The original way we determined the gpu version was based on downstream
bindings from android kernel.  A cleaner way is to get the version from
the compatible string.

Note that no upstream dtb uses these bindings.  But the code still
supports falling back to the legacy bindings (with a warning), so that
we are still compatible with the gpu dt node from android device
kernels.

1a4a66ddc7 drm/msm: remove qcom,gpu-pwrlevels bindings
The plan is to use the OPP bindings.  For now, remove the documentation
for qcom,gpu-pwrlevels, and make the driver fall back to a safe low
clock if the node is not present.

Note that no upstream dtb use this node.  For now we keep compatibility
with this node to avoid breaking compatibility with downstream android
dt files.

cca112ecf2 spi: Fixes for v4.10
The usual small smattering of driver specific fixes.  A few bits that
 stand out here:
 
  - The R-Car patches adding fallbacks are just adding new compatible
    strings to the driver so that device trees are written in a more
    robustly future proof fashion, this isn't strictly a fix but it's
    just new IDs and it's better to get it into mainline sooner to
    improve the ABI.
  - The DesignWare "switch to new API part 2" patch is actually a
    misleadingly titled fix for a bit that got missed in the original
    conversion.

 1) Handle multicast packets properly in fast-RX path of mac80211, from
    Johannes Berg.

 2) Because of a logic bug, the user can't actually force SW
    checksumming on r8152 devices. This makes diagnosis of hw
    checksumming bugs really annoying. Fix from Hayes Wang.

 3) VXLAN route lookup does not take the source and destination ports

Currently dp83867 driver returns error if phy interface type
PHY_INTERFACE_MODE_RGMII_RXID is used to set the rx only internal

Fix this by checking also the interface type if a particular delay

accordingly.

331c342552 i2c: do not enable fall back to Host Notify by default
Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.

For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
  in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
  dma-buf kerneldoc patches

It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during
this time might be useful.

I'd also like to backmerge -rc2+this into drm-intel next week, we have
quite a pile of patches waiting for the stuff in here.

Merge tag 'pm-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These fix a few issues in the intel_pstate driver, a documetation
  issue, a false-positive compiler warning in the generic power domains
  framework and two problems in the devfreq subsystem. They also update
  the MAINTAINERS entry for devfreq and add a new "compatible" string to
  the generic cpufreq-dt driver.

  Specifics:

   - Fix a few intel_pstate driver issues: add missing locking it two
     places, avoid exposing a useless debugfs interface and keep the
     attribute values in sysfs in sync (Rafael Wysocki).

   - Drop confusing kernel-doc references related to power management
     and ACPI from the driver API manual (Rafael Wysocki).

62a0d98a18 drm: allow to use mmuless SoC
Some SoC without MMU have display driver where a drm/kms driver
could be implemented.

Before doing such kind of thing drm/kms must allow to use mmuless devices.
This patch propose to remove MMU configuration flag and add a cma helper
function to help implementing mmuless display driver

version 4:
- add documentation about drm_gem_cma_get_unmapped_area()
- stub it MMU case

b400792732 This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
 regressions introduced during the merge window, and about half of
 the changes are for mach-omap2.
 
 A couple of patches are just cleanups and dead code removal that I would
 not normally have considered for merging after -rc2, but I decided to
 take them along with the fixes this time.
 
 Notable fixes include:
 
 - removing the skeleton.dtsi include broke a number of machines, and we
   have to put empty /chosen nodes back to be able to pass kernel command
   lines as before
 
 - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200,
   as it had been for no good reason for a long time.

6e092c8c04 PM / docs: Drop confusing kernel-doc references from infrastructure.rst
The references to drivers/base/power/main.c and
drivers/acpi/scan.c from Documentation/driver-api/infrastructure.rst
are confusing.  They both cause descriptions of functions that are
not relevant to device drivers at all to be generated and none of
them is sufficient to cover the API in a meaningful way.

Drop them for now.
