Subject: [PATCH v6 0/5] Mediatek MT7986 basic clock support
This patch series add basic clock support for mediatek mt7986 SoC.
It is based on patch series "Add basic SoC support for mediatek mt7986"
https://lore.kernel.org/all/[email protected]/
and "clk: mediatek: Add API for clock resource recycle"
https://lore.kernel.org/linux-arm-kernel/[email protected]/
---
v6: Used lowercase hex values in clock DT
v5: used builtin_platform_driver instead of CLK_OF_DECLARE
follow recent clk-mt8195 clock patch series:
https://lore.kernel.org/linux-arm-kernel/[email protected]/
v4:
According to the maintainer’s suggestion, this patch splits the previous
thread into independent patch series.
This patch include clock driver and device tree update

2.29.2
Add MT7986 clock support, include topckgen, apmixedsys,
infracfg, and ethernet subsystem clocks.
Signed-off-by: Sam Shih <[email protected]>
---
v5: used builtin_platform_driver instead of CLK_OF_DECLARE
follow recent clk-mt8195 clock patch series:
https://lore.kernel.org/linux-arm-kernel/[email protected]/
v4: separate clock part into a single patch series
Original thread:
https://lore.kernel.org/lkml/[email protected]/
v2: applied the comment suggested by reviewers:
- splited basic clock driver to apmixed, topckgen, and infracfg
- removed 1:1 factor clock
- renamed factor clock for easier to understand
