[RFC,v2,0/5] MIPS: ralink: peripheral clock gating driver

Message

NOGUCHI Hiroshi April 5, 2019, 12:01 a.m. UTC

Changelog:

v2:
  - moves ralink gating clock driver to drivers/clk/
  - describes the resources of gating clocks in devicetree
      and removes resource tables in source code
  - changes gating clock provider to platform_driver
  - changes PLL clock provider to platform_driver
  - replaces clk_* API calls to clk_hw_* APIs
  - uses BIT() macro
  - uses IS_ENABLED(CONFIG_COMMON_CLK) macro

------
This series introduce Mediatek/Ralink SoC's clock gating driver and
rework PLL clks as clock provider.

The gating clocks are different at individual SoCs.
Their resources are described with devicetree.

NOGUCHI Hiroshi (5):
  clk: ralink: add rt2880-clock driver
  dt-bindings: clk: add document for ralink clock driver
  mips: ralink: mt7620/76x8 use common clk framework
  mips: ralink: mt76x8: add nodes for PLL clocks and gating clocks
  mips: ralink: mt7620: add nodes for PLL	clocks and gating clocks
