Here is the large set of char and misc and other driver subsystem
changes for 6.0-rc1.
Highlights include:
- large set of IIO driver updates, additions, and cleanups
- new habanalabs device support added (loads of register maps
much like GPUs have)
- soundwire driver updates
- phy driver updates
- slimbus driver updates
- tiny virt driver fixes and updates
- misc driver fixes and updates
- interconnect driver updates
- hwtracing driver updates
- fpga driver updates
- extcon driver updates
- firmware driver updates
- counter driver update
- mhi driver fixes and updates
- binder driver fixes and updates
- speakup driver fixes
Full details are in the long shortlog contents.
All of these have been in linux-next for a while without any reported
problems.

Vdda regulators are related to both eDP and DP phy so that it should be
managed at eDP and DP phy driver instead of controller. This patch removes
vdda regulators related functions out of eDP/DP controller.

"ctrl_link" is the clock from DP_CTRL_PM module. The result of setting
the rate for it would be a call to dev_pm_opp_set_rate(). Instead of
saving the rate inside struct dss_module_power, call the
devm_pm_opp_set_rate() directly.

Make the necessary changes to the DP driver to use the qmp phy from the
common phy framework instead of rolling our own in the drm subsystem.
This also removes the PLL code and adds proper includes so things build.

add event thread to execute events serially from event queue. Also
timeout mode is supported which allow an event be deferred to be
executed at later time. Both link and phy compliant tests had been
done successfully.
Changes in v2:
-- Fix potential deadlock by removing redundant connect_mutex
-- Check and enable link clock during modeset
-- Drop unused code and fix function prototypes.
-- set sink power to normal operation state (D0) before DPCD read
Changes in v3:
-- push idle pattern at main link before timing generator off
-- add timeout handles for both connect and disconnect
Changes in v4:
-- add ST_SUSPEND_PENDING to handles suspend/modeset test operations
-- clear dp phy aux interrupt status when ERR_DPPHY_AUX error
-- send segment addr during edid read
-- clear bpp depth before MISC register write
Changes in v5:
-- add ST_SUSPENDED to fix crash at resume
Changes in v6:
-- at msm_dp_display_enable() do not return until resume_done to avoid
kms commit timeout

Add the needed DP PLL specific files to support
display port interface on msm targets.
The DP driver calls the DP PLL driver registration.
The DP driver sets the link and pixel clock sources.
Changes in v2:
-- Update copyright markings on all relevant files.
-- Use DRM_DEBUG_DP for debug msgs.
Changes in v4:
-- Update the DP link clock provider names
Changes in V5:
-- Addressed comments from Stephen Boyd, Rob clark.
Changes in V6:
-- Remove PLL as separate driver and include PLL as DP module
-- Remove redundant clock parsing from PLL module and make DP as
clock provider
-- Map USB3 DPCOM and PHY IO using hardcoded register address and
move mapping form parser to PLL module
-- Access DP PHY modules from same base address using offsets instead of
deriving base address of individual module from device tree.
-- Remove dp_pll_10nm_util.c and include its functionality in
dp_pll_10nm.c
-- Introduce new data structures private to PLL module
Changes in v7:
-- Remove DRM_MSM_DP_PLL config from Makefile and Kconfig
-- Remove set_parent from determin_rate API
-- Remove phy_pll_vco_div_clk from parent list
-- Remove flag CLK_DIVIDER_ONE_BASED
-- Remove redundant cell-index property parsing

Add the needed displayPort files to enable DP driver
on msm target.
"dp_display" module is the main module that calls into
other sub-modules. "dp_drm" file represents the interface
between DRM framework and DP driver.

-- Add support of pm ops in display port driver
-- Clear bpp depth bits before writing to MISC register
-- Fix edid read
