[PATCH v2 00/14] NVIDIA Tegra memory and power management changes for 5.14

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series:

  1. Adds CPU/core voltage bump before system is rebooted.
  2. Adds new devm_tegra_core_dev_init_opp_table() helper and switches
     Tegra memory drivers to use it.
  3. Adds compile-testing support to the Tegra memory drivers.
  4. Adds Tegra SoC core power domain support.

Changelog:

v2: - Added more clk stubs that should fix build error reported by the
      kernel bot to v1 for the T210 memory driver.

    - Added r-b from Krzysztof Kozlowski to the memory patches.

    - Added back voltage restore on detaching of coupled regulators to
      the T20 regulator coupler which previously got missed by accident.

    - Added new patch:

        regulator: core: Detach coupled regulator before coupling count is dropped

      It fixes skipped voltage balancing on detaching of regulators which I
      happened to notice due to the recent regression of the MAX77620 driver
      that made driver to re-probe and detach coupled regulators.

v1: - Merged previous patches into this single series.

    - Added ack from Rob Herring to the core domain DT binding patch.

    - Implemented suggestions that were given by Krzysztof Kozlowski:

        - Factored out soc_is_tegra() stub into standalone patch.
        - Updated tags of the "Fix compilation warnings on 64bit platforms"
          patch, added reported-by from lkp robot and removed suggested-by
          from Nathan Chancellor.
        - Switched to use use BIT() macro.

    - Added r-b from Krzysztof Kozlowski to "Enable compile testing for
      all drivers" patch.

    - Added r-b from Nathan Chancellor.

    - Dropped voltage floor/ceiling from devm_tegra_core_dev_init_opp_table()
      since only memory drivers now need to initialize voltage vote and they
      don't need floor/ceil. This was suggested by Viresh Kumar.

Dmitry Osipenko (14):
  regulator: core: Add regulator_sync_voltage_rdev()
  regulator: core: Detach coupled regulator before coupling count is
    dropped
  soc/tegra: regulators: Bump voltages on system reboot
  soc/tegra: Add stub for soc_is_tegra()
  soc/tegra: Add devm_tegra_core_dev_init_opp_table()
  soc/tegra: fuse: Add stubs needed for compile-testing
  clk: tegra: Add stubs needed for compile-testing
  memory: tegra: Fix compilation warnings on 64bit platforms
  memory: tegra: Enable compile testing for all drivers
  memory: tegra20-emc: Use devm_tegra_core_dev_init_opp_table()
  memory: tegra30-emc: Use devm_tegra_core_dev_init_opp_table()
  dt-bindings: soc: tegra-pmc: Document core power domain
  soc/tegra: pmc: Add core power domain
  soc/tegra: regulators: Support core domain state syncing
