[PATCH v3 0/3] SDM670 Global Clocks

[PATCH v3 0/3] SDM670 Global Clocks

[Richard Acayan]

Changes since v2:
 - drop GCC_SDCC1_BCR reset
 - reorder gcc-sdm845 and gcc-sdm670 if statements in bindings
 - add space
 - accumulate review tags

Changes since v1:
 - regenerate patches to fixed malformed patch
 - fix schema so that the parent clocks are specified correctly
 - remove core_bi_test_pll_se from new parent_data to match array sizes
 - reference correct frequency table for gcc_sdm670_cpuss_rbcpr_clk_src
 - set correct index for sdcc1_ice_core_clk_src

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
necessary.

[PATCH v3 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 from Snapdragon 670 and
document the differences between the SoC parent clocks.

Series looks good to me, but linux-next has 0f71ae945730 ("dt-bindings:
clk: qcom,gcc-*: use qcom,gcc.yaml") which conflicts with this addition.
Can you please rebase on top of linux-next, retest and submit a new
version?

Thanks,
Bjorn

[PATCH v3 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 v3 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
