Subject: [PATCH 13/17] MIPS: loongson32: Convert watchdog platform device to DT
Date: Sat, 29 Jul 2023 21:43:14 +0800 [thread overview]
Message-ID: <20230729134318.1694467-14-keguang.zhang@gmail.com> (raw)
In-Reply-To: <20230729134318.1694467-1-keguang.zhang@gmail.com>
Add watchdog device node for Loongson-1 boards,
and drop the legacy platform device and data accordingly.
