[PATCH v2 00/16] Introduce STM32 DDR PMU for STM32MP platforms
Posted by Clément Le Goffic 2 months, 3 weeks ago 
This patch series introduces the DDR Performance Monitor (DDRPERFM) support for
STM32MP platforms.

The series firstly improves the STM32MP25 RCC driver to make it usable
as an access controller, needed for driver probe.

It also includes the addition of device tree bindings, the HDP driver,
documentation and updates to the device tree files for
STM32MP13, STM32MP15 and STM32MP25 SoCs.
The series also updates the MAINTAINERS file to include myself as the
maintainer for the STM32 DDR PMU driver.

Changes in v2:
- MAINTAINERS:
    Due to reorganisation, my contract with ST ends at the end of this month
    and I will no longer have access to this mailbox.
    Therefore, I will be available for any mission related to embedded and
    kernel linux.
    Change email address in MAINTAINERS file for STM32 DDR PMU driver.
- devicetrees:
  -stm32mp257f-dk: add LPDDR4 channel
  -stm32mp257f-ev1: add DDR4 channel
- dt-bindings:
  - perf:
    - Change Maintainer email address
    - Drop obvious descriptions (clocks and reset property)
    - Drop redundant "bindings" in commit message
    - Drop unneedded "stm32mp151-ddr-pmu" compatible
    - s/st,dram-type/memory-channel/, memory-channel property is not in
      dtschema library so it will produce an error in the v2.
  - rcc:
    - Add required "access-controller-cells" property in example
  - ddr-channel:
    - Add bindings as per jedec,lpddrX-channel bindings
- driver:
  - Substitute the parsing of the 'st,dram-type' vendor devicetree
    property value with the parsing of the [lp]ddr channel compatible
  - Remove unneeded "stm32mp151-ddr-pmu" compatible
  - Use dev_err_probe when possible
  - Assert and deassert reset line unconditionnaly
  - Use `devm_reset_control_get_optional_exclusive` instead of
    `of_property_present` then `devm_reset_control_get`
  - Use `devm_clk_get_optional_prepared` instead of `of_property_present`
    then `devm_clk_get_prepared`
  - Disable and unprepare the clock at end of probe
  - Add io.h include as per LKP test report
  - Removed `of_match_ptr` reference in `platform_driver` struct
  - Add `pm_sleep_ptr` macro for `platform_driver` struct's `pm` field
  - Link to v1: https://lore.kernel.org/r/20250623-ddrperfm-upstream-v1-0-7dffff168090@foss.st.com

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit d7b8f8e20813f0179d8ef519541a3527e7661d3a

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
