Subject: [PATCH v1 0/2] Add support for StarFive JHB100 UART Routing
Date: Sat, 29 Aug 2026 23:51:16 -0700	[thread overview]
Message-ID: <20260830065118.51551-1-changhuang.liang@starfivetech.com> (raw)

StarFive JHB100 UART Routing allows dynamic routing of inputs between
built-in UARTs and physical serial I/O ports, enabling use cases such
as Host <-> BMC communication via UARTs.

This series has been tested on the EVB1 board.

This series depends on the series:
