Subject: [PATCH v2 0/1] riscv: dts: starfive: jh7110-milkv-mars: enable usb0 host function
Date: Fri, 15 Nov 2024 22:17:07 -0800	[thread overview]
Message-ID: <20241116061719.36409-2-e@freeshell.de> (raw)

Enable host mode JH7110 on-chip USB for Milk-V Mars by setting host mode
and connect vbus pinctrl.

This functionality depends on:

1. commit e10c52e7e064038d9bd67b20bf4ce92077d7d84e
"phy: starfive: jh7110-usb: Fix link configuration to controller"

2. Setting the USB over-current register to disable. This is done at
bootloader phase, for example U-Boot:
https://patchwork.ozlabs.org/project/uboot/patch/20241012031328.4268-6-minda.chen@starfivetech.com/

If the over-current register is not prepared for us then the result is no
change in functional outcome with this patch applied; there is an error
visible to the user and this additional usb configuration fails (same as
it is now). The existing three VL805 connected USB ports via PCIe on 
Milk-V Mars are not affected.

Changes since v1:
 - series name (was "[PATCH] riscv: dts: starfive: jh7110-milkv-mars: set host mode and vbus pin for on-chip USB 2.0")
 - adjust pin label to obey dtschema
 - use cover letter
