Subject: [PATCH 0/6] arm64: g12a: add support for DVFS
Date: Mon, 29 Jul 2019 15:26:16 +0200	[thread overview]
Message-ID: <20190729132622.7566-1-narmstrong@baylibre.com> (raw)

The G12A & G12B SoCs has kernel controllable CPU clocks and PWMs for
voltage regulators.

This patchsets moves the meson-g12a.dtsi to meson-g12-common.dtsi to simplify
handling the G12A & G12B differences in the meson-g12a.dtsi & meson-g12b.dtsi
files, like the OPPs and CPU nodes.

Then G12A & G12B OPP tables are added, followed by the CPU voltages regulators
in each boards DT.

It was voluntary chosen to enabled DVFS (CPU regulator and CPU clocks) only
in boards, to make sure only tested boards has DVFS enabled.

This patchset :
- moves the G12A DT to a common g12a-common dtsi
- adds the G12A and G12B OPPs
- enables DVFS on all supported boards

Dependencies:
- None

Changes since RFT/RFC v3 at [3]:
- Rebased on v5.3/fixes branch to take in order the last g12a.dtsi changes.
- added Martin's review tags

Changes since RFT/RFC v2 at [2]:
- Rebased on linux-amlogic v5.3/dt64

Changes since RFT/RFC v1 at [1]:
- Fixed G12B dtsi by adding back the sdio quirk
- Fixed G12A dtsi unwanted sdio quirk removal
