Subject: [PATCH 0/3] Support MSM8916 USB PHY + UDC in qcom_defconfig
Date: Sat, 12 Apr 2025 19:39:50 +0000 [thread overview]
Message-ID: <20250412-msm8916-usb-v1-0-2925239caf4b@samcday.com> (raw)
The MSM8916 SoC includes a ChipIdea UDC. The U-Boot driver for this UDC
is quite old, and did not support USB gadget driver model. As a result,
it could not be built alongside the DWC3 driver. This meant that
qcom_defconfig could not include support for USB on MSM8916.
This series adds support to build ChipIdea UDC with DM_USB_GADGET and
ensures that the newly introduced driver is registered from the MSM EHCI
glue driver.
The ChipIdea UDC driver continues to work without DM_USB_GADGET. I
tested these changes by building dragonboard410c_defconfig (which does
not enable DM_USB_GADGET), booting it, and then chain-booting (via
fastboot) another u-boot build built with qcom_defconfig. USB gadget
mode worked in both builds.
