[U-Boot] [PATCH v2 0/5] sunxi: H6: Enable USB (2.0) support

[U-Boot] [PATCH v2 0/5] sunxi: H6: Enable USB (2.0) support

[Andre Przywara]

Hi,

a minor update to v1, adding PortM support as per Icenowy's comment and
dropping the DT change. We still need the latter for support the USB0
port on some boards, but this takes another route now (syncing back
from Linux).
---------------

This series enables USB support on the H6 boards. This is mostly just
adding some missing pieces here and there, the actual controller and PHY
are very similar to the previous ones, if not identical.
This is for the 2.0 ports only at the moment, USB 3.0 requires some more
work to make U-Boot's driver compliant to the kernel's DT bindings.

The Pine H64 shares a similar problem as the Pine64+ boards regarding
the upper USB port. To enable this port, we need a patch from Paul [1]
and changes to the DT [2]. But this is orthogonal to this series.

Patch 1 is a drive-by patch to bring SUNXI_GPIO to Kconfig, as this was
lingering in one of my branches for a while.
Patch 2 enables GPIO support for the H6, as this is needed for the Pine
H64 to enable the VBUS regulator.
Patch 3 adds the clock and reset gates mappings for the USB controller and
the PHY, the values are taken from the manual and verified against
Linux.
Patch 4 adds some code to the PHY driver to skip over not implemented
PHYs, as the H6 uses a PHY0/PHY3 combination in the DT.
Patch 5 then eventually enables USB in the existing defconfigs.

Cheers,
Andre.

[U-Boot] [PATCH v2 1/5] sunxi: move SUNXI_GPIO to Kconfig

[Andre Przywara]

Probably for no particular reason SUNXI_GPIO was still defined the "old
way", in header files only.

Introduce SUNXI_GPIO to the Kconfig file in drivers/gpio to remove
another line from our dreadful config_whitelist.txt.

[U-Boot] [PATCH v2 2/5] sunxi: gpio: Enable support for H6 pin controller

[Andre Przywara]

The Allwinner H6 pin controller is not really special, at least not when
it comes to normal GPIO operation.

Add the H6 compatible strings to the list of recognised strings, to make
GPIOs work for H6 boards.

[U-Boot] [PATCH v2 3/5] sunxi: clocks: Add H6 USB clock gates and resets

[Andre Przywara]

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.

[U-Boot] [PATCH v2 4/5] sunxi: phy: Add USB PHY support for Allwinner H6

[Andre Przywara]

The USB PHY used in the Allwinner H6 SoC has some pecularities (as usual),
which require a small addition to the USB PHY driver:
In this case the second PHY is PHY3, not PHY1, so we need to skip number
1 and 2 in the code. Just use the respective code from Linux for that.

[U-Boot] [PATCH v2 5/5] sunxi: H6: Enable USB for existing boards

[Andre Przywara]

So far USB was not enabled for the Allwinner H6 boards, as the PHY
driver was not ready and the clock gates were missing. Since this is now
fixed, let's add the PHY and the OHCI/EHCI drivers to the build, for
all existing H6 boards.
