[PATCH v3 00/11] drm/msm/dsi_phy: Replace parent names with clk_hw pointers

[PATCH v3 00/11] drm/msm/dsi_phy: Replace parent names with clk_hw pointers

[Marijn Suijten]

parent_hw pointers are easier to manage and cheaper to use than
repeatedly formatting the parent name and subsequently leaving the clk
framework to perform lookups based on that name.

This series starts out by adding extra constructors for divider, mux and
fixed-factor clocks that have parent_hw(s) pointer argument(s) instead
of some DT index or name.  Followed by individual patches performing the
conversion, one DSI PHY at a time.

dsi_phy_28nm_8960 includes an extra fixup to replace "eternal"
devm_kzalloc allocations (for the lifetime of the device) with
stack-local char arrays, like all the other DSI PHY drivers.

(Questions from v1 cover letter regarding the future of these drivers
 is omitted for brevity.)

And with enough future improvements out of the way, let's round out this
patch-series by stating that it has been successfully tested on:

- Sony Nile Discovery (Xperia XA2 Ultra): 14nm;
- Sony Seine PDX201 (Xperia 10II): 14nm;
- Sony Loire Suzu (Xperia X): 28nm.

And no diff is observed in debugfs's clk_summary.

Unfortunately all other devices in my collection with a 7/10nm DSI PHY
have a DSC panel which we have yet to get working.

Changes since v2:
- in fixed-factor:
  - Reorder if - else if change to consume less diff;
  - Go over 80-char column lint when adding new arguments to function
    calls, instead of reflowing all arguments to adhere to this limit;
    also consuming less diff.

v2: https://lore.kernel.org/linux-arm-msm/20220601220747.1145095-1-marijn.suijten@somainline.org/

Changes since v1:

- Moved indentation changes to separate patch (Dmitry);
- dsi_phy_28nm_8960: move clock name allocation removal prior to
  parent_hw refactor;
- Remove vco_name stack-local char array in favour of reusing clk_name
  (Dmitry);
- Inserted additional patch to replace hardcoded char-array length
  constant 32 with sizeof(clk_name).

[PATCH v3 04/11] drm/msm/dsi/phy: Reindent and reflow multiline function calls

[Marijn Suijten]

Patch 613cbd1da3c9 ("drm/msm/dsi: use devm_clk_*register to registe DSI
PHY clocks") introduced the devm_ prefix to clk_hw registration calls,
without updating the indentation of the arguments on the following
lines.

Similarly e55b3fbbbbc8 ("drm/msm/dsi: drop PLL accessor functions")
moved from pll_write to dsi_phy_write without updating the indentation
of followup arguments either.

Preparing for a series that heavily touches the clk calls, reflow and
reindent function calls that are adhering to an 80-char column limit by
spanning multiple lines.  Where function names are very long the
arguments are indented with a fixed number of two tab characters instead
of aligning with the opening parenthesis of the function call.

[PATCH v3 04/11] drm/msm/dsi/phy: Reindent and reflow multiline function calls

[Marijn Suijten]

Patch 613cbd1da3c9 ("drm/msm/dsi: use devm_clk_*register to registe DSI
PHY clocks") introduced the devm_ prefix to clk_hw registration calls,
without updating the indentation of the arguments on the following
lines.

Similarly e55b3fbbbbc8 ("drm/msm/dsi: drop PLL accessor functions")
moved from pll_write to dsi_phy_write without updating the indentation
of followup arguments either.

Preparing for a series that heavily touches the clk calls, reflow and
reindent function calls that are adhering to an 80-char column limit by
spanning multiple lines.  Where function names are very long the
arguments are indented with a fixed number of two tab characters instead
of aligning with the opening parenthesis of the function call.

[PATCH v3 05/11] drm/msm/dsi_phy_28nm_8960: Use stack memory for temporary clock names

[Marijn Suijten]

The clock names formatted into the hw_clk's init structure are only used
for the duration of the registration function where they are kstrdup'ed,
making it unnecessary to keep the allocations alive for the duration of
the device (through devm).

Just like the other DSI PHY PLL clock trees, use a stack-local char
array and save on memory outside of the pll_28nm_register function.

[PATCH v3 06/11] drm/msm/dsi/phy: Replace hardcoded char-array length with sizeof()

[Marijn Suijten]

Now that the last DSI PHY PLL driver (dsi_phy_28nm_8960) has been
converted to use a simple stack-local char-array instead of a
devm_kzalloc heap allocation we can safely call sizeof() on every string
variable (that's now a sized array instead of a pointer) passed into
snprintf instead of hardcoding the size.

[PATCH v3 06/11] drm/msm/dsi/phy: Replace hardcoded char-array length with sizeof()

[Marijn Suijten]

Now that the last DSI PHY PLL driver (dsi_phy_28nm_8960) has been
converted to use a simple stack-local char-array instead of a
devm_kzalloc heap allocation we can safely call sizeof() on every string
variable (that's now a sized array instead of a pointer) passed into
snprintf instead of hardcoding the size.

[PATCH v3 07/11] drm/msm/dsi_phy_28nm_8960: Replace parent names with clk_hw pointers

[Marijn Suijten]

parent_hw pointers are easier to manage and cheaper to use than
repeatedly formatting the parent name and subsequently leaving the clk
framework to perform lookups based on that name.

Stephen, do we stand a chance of landing patches 1-3 into 5.20? We would 
like to merge the series into 5.21 through the msm-next. Landing clk 
patches in 5.20 would save us from using immutable branches, etc.
