Subject: [PATCH 0/7] arm64: sunxi: h616: Add USB support
Date: Mon, 12 Sep 2022 00:59:38 +0100 [thread overview]
Message-ID: <20220911235945.6635-1-andre.przywara@arm.com> (raw)
The USB IP used in the Allwinner H616 SoC is very similar to the one
used in the H3 chip: it contains four USB 2.0 host controllers and four
PHYs, where the first PHY is shared with a separate USB-OTG controller.
But out of the four ports, only port 2 works out of the box, the other
ports require some resources and registers of port 2 to be enabled as
well.
Implement the required workaround in the Allwinner USB PHY driver, and
key this off the respective compatible string. This core code is
contained in patch 3/7. The first two patches add the respective DT
binding documentation, whereas patch 4/7 encodes all the configuration
options for the H616 USB PHY into the driver.
The last three patches add the respective devicetree nodes, to the H616
.dtsi, but also to the DTs of the two supported boards.
This allows USB to be used on any H616 based machine. This was tested on
the X96 Mate box.
This series is an update on what was included in earlier versions of the
initial H616 support series, but was later dropped to get the basic
support in first more quickly.
It is now based on v6.0-rc4 and is also available here:
https://github.com/apritzel/linux/commits/h616-usb
Please have a look and test on your hardware, especically on all ports
exposed on header pins of the OrangePi Zero2 board.
Cheers,
Andre
