PATCH 1/1 ARM64: dts: amlogic: Add hiu and periphs buses
From: Carlo Caione <[email protected]>
Add two new buses in the DTS: hiu and periphs buses.
In the Amlogic S905/GXBB SoC several devices (clock / eth / pin controllers, etc...) are mapped under these two buses. Add them in the DT before starting to add new devices.

Looks sane, but where did you get that info from? The others I had found in an iomap node or so but did not spot these.

For hiubus you can see the io_hiubus_base node in the gxbb_p201.dts DT file. For the periphs bus is a bit more tricky. The only reasonable information I found is oddly in drivers/amlogic/hdmi/hdmi_tx_20/hw/reg_ops.c.
