We're experimenting a bit with the process this time, with Dmitry
collecting display patches and merging them into msm-next with me
handling the gpu/etc side of things.  Summary of interesting new bits
and pieces

* dpu + dp support for sc8180x
* dp support for sm8350
* dpu + dsi support for qcm2290
* 10nm dsi phy tuning support
* bridge support for dp encoder
* gpu support for additional 7c3 SKUs
* assorted cleanups and fixes

Register logging was used during early stages of msm driver development
to compare upstream and downstream register traces. However the tool was
never updated to work with mdp5 hardware. Later it was dropped
completely when Rob imported freedreno tools into mesa. All this makes
DRM_MSM_REGISTER_LOGGING irrelevant now, so it can be dropped.

<title>drm/dp: Move DisplayPort helpers into separate helper module</title>

<id>urn:sha1:adb9d5a2cc77e8aefe98fe4c11656c5b7025c248</id>
<content type='text'>
Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c

This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:

Before:
	drm_kms_helper.ko:	447480 bytes

After:
	drm_dp_helper.ko:	216632 bytes
	drm_kms_helper.ko:	239424 bytes

For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.

v3:
	* fix include statement in DRM selftests
v2:
	* move DP helper code into dp/ (Jani)

<content type='text'>
When CONFIG_COMMON_CLOCK is disabled, the 8996 specific
phy code is left out, which results in a link failure:

ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'

This was only exposed after it became possible to build
test the driver without the clock interfaces.

Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

<title>drm/msm/dsi: Support NO_CONNECTOR bridges</title>

<id>urn:sha1:63885c16d6e2077d23abdf9cb67f5507ded35967</id>
<content type='text'>
For now, since we have a mix of bridges which support this flag, which
which do *not* support this flag, or work both ways, try it once with
NO_CONNECTOR and then fall back to the old way if that doesn't work.
Eventually we can drop the fallback path.

v2: Add missing drm_connector_attach_encoder() so display actually comes
    up when the bridge properly handles the NO_CONNECTOR flag

<content type='text'>
Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:

aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'

ld.lld: error: undefined symbol: qcom_scm_is_available
&gt;&gt;&gt; referenced by adreno_gpu.c
&gt;&gt;&gt;               gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a

This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.

This appears to be an endless problem, so try something different this
time:

 - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
   but that is simply selected by all of its users

 - All the stubs in include/linux/qcom_scm.h can go away

 - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
   allow compile-testing QCOM_SCM on all architectures.

 - To avoid a circular dependency chain involving RESET_CONTROLLER
   and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
   According to my testing this still builds fine, and the QCOM
   platform selects this symbol already.
