drm/msm/dpu: hw_blk: make dpu_hw_blk empty opaque structure

2021-06-23T14:33:54+00:00

The code does not really use dpu_hw_blk fields, so drop them, making
dpu_hw_blk empty structure.

drm/msm: add support to take dpu snapshot

2021-06-23T14:32:13+00:00

Add the msm_disp_snapshot module which adds supports to dump dpu
registers and capture the drm atomic state which can be used in
case of error conditions.

changes in v5:
 - start storing disp_state in msm_kms instead of dpu_kms
 - get rid of MSM_DISP_SNAPSHOT_IN_* enum by simplifying the functions
 - move snprintf inside the snapshot core by using varargs
 - get rid of some stale code comments
 - allow snapshot module for non-DPU targets

drm/msm/dsi: drop msm_dsi_pll abstraction

2021-04-07T18:05:46+00:00

Drop the struct msm_dsi_pll abstraction, by including vco's clk_hw
directly into struct msm_dsi_phy.

drm/msm/dsi: fuse dsi_pll_* code into dsi_phy_* code

2021-04-07T18:05:45+00:00

Each phy version is tightly coupled with the corresponding PLL code,
there is no need to keep them separate. Fuse source files together in
order to simplify DSI code.

drm/msm/dp: Use qmp phy for DP PLL and PHY

2020-09-15T17:54:35+00:00

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.

drm/msm/dp: add audio support for Display Port on MSM

2020-09-15T17:54:34+00:00

Introduce audio support for Display Port on MSM chipsets.
This change integrates DP audio sub-module with the main
Display Port platform driver.

In addition, this change leverages hdmi_codec_ops to expose
the operations to the audio driver.

drm/msm/dp: add support for DP PLL driver

2020-09-15T17:54:34+00:00

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

Changes in v8:

-- Unregister hardware clocks during driver cleanup

Changes in v9:

-- Remove redundant Kconfig option DRM_MSM_DP_10NM_PLL

Changes in v10:

-- Limit 10nm PLL function scope

drm/msm/dp: add displayPort driver support

2020-09-15T17:54:34+00:00

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.

Changes in v12:

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