Restructure MSM DSI PHY drivers. What started as an attempt to grok the
overcomplicated PHY drivers, has lead up to the idea of merging PHY and
PLL code, reducing abstractions, code duplication, dropping dead code,
etc.

The patches were mainly tested on RB5 (sm8250, 7nm) and DB410c (apq8016,
28nm-lp) and lightly tested on RB3 (sdm845, 10nm).

This patchet depends on the patch "clk: fixed: add devm helper for
clk_hw_register_fixed_factor()", which was merged in 5.12-rc1:
https://lore.kernel.org/r/20210211052206.2955988-4-daniel@0x0f.com


Changes since v3:
 - Rename save_state/restore_state functions/callbacks
 - Still mention DSI_1 when determining settings for slave PHYs in 14nm
   and 28nm drivers.
 - Stop including the external dependency merged upstream long ago. It
   is properly mentioned in the patchset description.

Changes since v2:
 - Drop the 'stop setting clock parents manually' patch for now together
   with the dtsi changes. Unlike the rest of patchset it provides
   functional changes and might require additional discussion.
   The patchset will be resubmitted later.

Changes since v1:
 - Rebase on top of msm/msm-next
 - Reorder patches to follow logical sequence
 - Add sc7180 clocks assignment
 - Drop sm8250 clocks assignment, as respective file is not updated in
   msm/msm-next

Changes since RFC:
 - Reorder patches to move global clock patches in the beginning and
   dtsi patches where they are required.
 - remove msm_dsi_phy_set_src_pll() and guess src_pll_id using PHY usecase.

DSI PHY init callback would either map dsi_phy_regulator or dsi_phy_lane
depending on the PHY type. Replace those callbacks with configuration
options governing mapping those regions.

The only PLL using multiple enable sequences is the 28nm PLL, which just
does the single step in the loop. Push that support back into the PLL
code.

Move all PLL-related callbacks into struct msm_dsi_phy_cfg. This limits
the amount of data in the struct msm_dsi_pll.

With the current upstream driver the msm_dsi_phy_type enum does not make
much sense: all DSI PHYs are probed using the dt bindings, the phy type
is not passed between drivers. Use quirks in phy individual PHY drivers
to differentiate minor harware differences and drop the enum.

msm_dsi_pll_set_usecase() function is not used outside of individual DSI
PHY drivers, so drop it in favour of calling the the respective
set_usecase functions directly.

All MSM DSI PHYs provide two clocks: byte and pixel ones.
Register/unregister provided clocks from the generic place, removing
boilerplate code from all MSM DSI PHY drivers.

Use devres-enabled version of clock registration functions. This lets us
remove dsi_pll destroy callbacks completely.

Use devm_of_clk_add_hw_provider() to register provided clocks. This
allows dropping the remove function alltogether.

These drivers do not use vco_delay variable, so drop it from all of
them.

Instead of setting the variable and then using it just in the one place,
determine vco_delay directly at the PLL configuration time.

10nm and 7nm already do not use these helpers, as they handle setting
slave DSI clocks after enabling VCO. Modify the rest of PHY drivers to
remove unnecessary indirection and drop enable_seq/disable_seq PLL
callbacks.

	dri-devel, freedreno, linux-clk, Stephen Boyd

Make save_state/restore callbacks accept struct msm_dsi_phy rather than
struct msm_dsi_pll. This moves them to struct msm_dsi_phy_ops, allowing
us to drop struct msm_dsi_pll_ops.

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

Replace PLL accessor functions (pll_read/pll_write*) with the DSI PHY
accessors, reducing duplication.

All PHY drivers would map dsi_pll area. Some PHY drivers would also
map dsi_phy area again (a leftover from old PHY/PLL separation). Move
all ioremaps to the common dsi_phy driver code and drop individual
ioremapped areas from PHY drivers.

The 7nm, 10nm and 14nm drivers would store interim data used during
VCO/PLL rate setting in the global dsi_pll_Nnm structure. Move this data
structures to the onstack storage. While we are at it, drop
unused/static 'config' data, unused config fields, etc.

The src_truthtable config is not used for some of phys, which use other
means of configuring the master/slave usecases. Inline this function
with the goal of removing src_pll_id argument in the next commit.

Phy driver already knows the source PLL id basing on the set usecase and
the current PLL id. Stop passing it to the phy_enable call. As a
reminder, dsi manager will always use DSI 0 as a clock master in a slave
mode, so PLL 0 is always a clocksource for DSI 0 and it is always a
clocksource for DSI 1 too unless DSI 1 is used in the standalone mode.

Hey Dmitry,
  Just wanted to give you a heads up.  Peter Collingbourne reported
today that his db845c wasn't booting to display for him on his 4k
monitor. It works fine on a 1080p screen, and while 4k isn't supported
(yet?),  normally the board should fall back to 1080p when connected
to a 4k monitor.  I was able to reproduce this myself and I see the
errors below[1].

I dug back and found that things were working ok on v5.12 w/ the
recently merged commit d1a97648ae028 ("drm/bridge: lt9611: Fix
handling of 4k panels"), and started digging around.

Seeing a bunch of changes to the
drivers/gpu/drm/msm/dsi/phy/dsi_phy_10nm.c file, I tried reverting a
chunk of the changes since 5.12 to that, and that got it working
again. I've narrowed it down to this change -
001d8dc33875 ("drm/msm/dsi: remove temp data from global pll
structure") upstream (also reverting following 6e2ad9c3bfca and
36c5dde5fdf0 first - but its reverting this change that actually makes
it work again).

I've not managed to really look into the change to see what might be
going wrong yet (its late and I'm about to crash), but I wanted to
give you a heads up. If you have any ideas for me to try I'm happy to
give them a go.

thanks

It looks like I made a mistake testing these patches with the splash
screen disabled.
Stephen Boyd has proposed a fix few days ago (will be included into
the 5.13). Could you check that it fixes the problem for you?
