[PATCH 0/3] SDM670 Global Clocks

[PATCH 0/3] SDM670 Global Clocks

[Richard Acayan]

This patch series adds global clocks essential for features of the Qualcomm
Snapdragon 670 (hopefully) cleanly into the SDM845 driver without doing
runtime fixups like in Google's bonito kernel (see patch 3).

This series (mostly patch 2) affects kernels made for Snapdragon 845 and
might need some further testing on SDM845 devices. I do not have a
Snapdragon 845-based device so someone else will have to double check if
it is necessary.

something wrong.

[PATCH 1/3] dt-bindings: clock: gcc-sdm845: add sdm670 global clocks

[Richard Acayan]

The Snapdragon 670 clocks will be added into the sdm845 gcc driver. Most
of the new clocks, GDSCs, and resets already have reserved IDs but there
are some resources that don't. Add the new clock and extra BCR from
Snapdragon 670 and document the differences between the SoC parent clocks.

What you want here I think is 'minItems: 3' and then restrict the clocks 
to 3 or 5 in the if/then schema.

Right. I'll make sure to set up CI locally before my next series.

Yes, thanks for directing me. I found what I needed in
Documentation/devicetree/bindings/clock/qcom,rpmcc.yaml.

[PATCH 2/3] clk: qcom: gcc-sdm845: use device tree match data

[Richard Acayan]

This driver will support more than one SoC's set of clocks, and set of
GDSCs. This behavior would be unclean with hard-coded static variables.
Support it by grabbing clocks, GDSCs, and BCRs in the match data.

[PATCH 3/3] clk: qcom: gcc-sdm845: add sdm670 global clock data

[Richard Acayan]

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and
adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while
also removing some GDSCs. Despite these differences, there are many
similarities with SDM670. Add data for SDM670 in the driver for SDM845 to
reuse the most of the clock data.

Advantages and disadvantages of this approach:
 + maintenance applies to both sdm670 and sdm845 by default
 + less duplicate code (clocks) means smaller distro/pre-built kernels
   with all drivers enabled
 - clocks for both SoC's must be compiled if the user wants clocks for one
   specific SoC (both or none)
 - additional testing needed for sdm845 devices
