[PATCH 0/2] serial: add Ambarella CV75 8250_dw quirks

From: Long Zhao via B4 Relay

Date: Fri Oct 09 2026 - 07:09:09 EST


Split from the combined CV75 bring-up series. The 8250_dw driver does
not depend on ARCH_AMBARELLA. The binding uses the ambarella vendor
prefix, which is added by the SoC series and is not in mainline yet;
dt_binding_check needs that prefix.

These patches match the UART patches in the combined v9.
