Subject: [PATCH v1] arch: arm64: dts: meson: a1: add assigned-clocks for usb node
Date: Wed, 24 Jan 2024 16:06:23 +0300 [thread overview]
Message-ID: <20240124130623.3471236-1-avromanov@salutedevices.com> (raw)
To ensure proper functionality of USB, it is necessary to use
the rate of 64000000 for CLKID_USB_BUS. For instance, adb may
not function correctly without this setting. This information
has been derived from the vendor SDK.
