[PATCH v6 0/6] ARM: sunxi: Convert sun4i/sun7i series SoCs to sunxi-ng CCU

From: Priit Laes
Date: Fri Jul 14 2017 - 10:51:07 EST


This serie brings A10 (sun4i) and A20 (sun7i) SoCs into the
sunxi-ng world. With this patchset we now support all the clocks
in sun4i/sun7i SoCs.

As mentioned in sun5i conversion, this is pretty much standard
stuff as most of the required clocks were already implemented in
the sunxi-ng framework.

In order to make cross-tree merges bisectable, device trees are
currently using plain numbers instead of defines.

Changes from v5:
- Added reviewed-by tags for Wens (A10/A20 dts bindings)
- Fix hdmi clock parents (Jonathan Liu)
- Add missing TVE0/1 reset bits (Olliver Schinagl)
- Fix divider clock's fixed postdivider logic again (Maxime Ripard)
- Set CLK_SET_RATE_PARENT for main hdmi and gpu clocks (Jonathan Liu)

Changes from v4:
- Add CLK_SET_RATE_PARENT to "sata" clock.
- Add proper postdivider support for divider clock.

Changes from v3:
- Add support for fixed post-divider support for DIV clocks.
- Fix wrong clk_ops for SATA. Spotted by Jonathan Liu.
- Use numeric values for clock indices to make merging somewhat easier
- Create separate sun7i/a20 specific header.

Changes from v2:
- Rename driver and relevant files to sun4i-a10-ccu.
- Drop mmc output and sample clocks for sun4i-a10.
- Rename CSI ISP clock to SCLK as it is called on other variants.
- Add comment on why PLL6 is used as AHB parent.
- Fix parents for out_a/out_b clocks.
- Stop exporting PLL_PERIPH_SATA gate. Driver takes care of gate.
- Rework SATA clock handling.
- Fix ahb gate parents.
- Simplefb clock fixes (add dependencies for HDMI/LVDS clocks).
- Fixes for pll-ve and pll-video1 clocks pointed out by Jonathan Liu.
- Adapt to latest upstream changes from sunxi-next.

Changes from v1:
- Drop useless comments
- Add support for A10 / sun4i.
- Rename driver to sunxi-a10-a20.
- Add previously unimplemented clocks.
- Document the audio pll hardcoded post-divider
- Add Acked-by: Rob Herring <robh at kernel.org> on patch 4
