[PATCH v3 0/4] soc: amlogic: clk-measure: add A1 and T7 support

[PATCH v3 0/4] soc: amlogic: clk-measure: add A1 and T7 support

[Jian Hu via B4 Relay]

This series adds Amlogic clock measurement support for A1 and T7 SoCs,
including binding updates, driver additions, and device tree enablement.

Signed-off-by: Jian Hu <jian.hu@amlogic.com>
---
Changes in v3:
- Place the clock-measure node after pwm_ao_gh node for t7.
- Link to v2: https://lore.kernel.org/r/20260415-clkmsr_a1_t7-v2-0-02b6314427e6@amlogic.com

Changes in v2:
- Add const for a1 and t7 clock measure table.
- Use b4 to send this series.
- Link to v1: https://lore.kernel.org/all/20260410100329.3167482-1-jian.hu@amlogic.com

Gentle ping. The patches have received review, could you please take
another look when you have time?

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v7.3/arm64-dt)

[3/4] arm64: dts: meson: a1: Add clk measure support
      https://git.kernel.org/amlogic/c/dd3d4327240dbd5e4a256f7428f92f454e23edba
[4/4] arm64: dts: amlogic: t7: Add clk measure support
      https://git.kernel.org/amlogic/c/d0a92020bb87b45a235d9d1f9ce76494e9ed02ca

These changes has been applied on the intermediate git tree [1].

The v7.3/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
