2021-01-25clk: sunxi: Add support for H616 clocksJernej Skrabec3-0/+128

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass11-11/+11
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-11-17clk: sunxi: add compatible string for V3Icenowy Zheng1-0/+2
A new compatible string is introduced for V3 CCU, because it has a few extra features available. Add the compatible string to the clock driver. As the extra features are not touched, just share the description struct now. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>

2019-07-16sunxi: clocks: Add H6 USB clock gates and resetsAndre Przywara1-0/+29
To enable USB support in U-Boot, add the required clock and reset gates to the H6 clock driver. Once enabled, the generic EHCI/OCHI drivers will pick them up from there automatically.

GMAC reset reg offset added by below commit seems to assume it as EMAC but R40 indeed using GMAC. "clk: sunxi: Implement EMAC, GMAC clocks, resets" (sha1: 68620c9698f109c1f001f80d282138a5c67cabef) So, fix by updating the reg offset for RST_BUS_GMAC.

2019-01-30sunxi: clk: enable clk and reset for CCU devicesAndre Przywara1-0/+12
Some Allwinner clock devices have parent clocks and reset gates itself, which need to be activated for them to work. Add some code to just assert all resets and enable all clocks given. This should enable the A80 MMC config clock, which requires both to be activated. The full CCU devices typically don't require resets, and have just fixed clocks as their parents. Since we treat both as optional and enabling fixed clocks is a NOP, this works for all cases, without the need to differentiate between those clock types.

2019-01-29sunxi: clk: A80: add MMC clock supportAndre Przywara1-1/+27
The A80 handles resets and clock gates for the MMC devices differently, outside of the CCU IP block. Consequently we have a separate clock device with a separate binding for that. Implement that with the respective clock gates and resets to allow the A80 taking part in the DM_MMC game.

Add common reset driver for all Allwinner SoC's. Since CLK and RESET share common DT compatible, it is CLK driver job is to bind the reset driver. So add CLK bind call on respective SoC driver by passing ccu map descriptor so-that reset deassert, deassert operations held based on ccu reset table defined from CLK driver. Select DM_RESET via CLK_SUNXI, this make hidden section of RESET since CLK and RESET share common DT compatible and code.
