Subject: [PATCH v2 4/9] aspeed/wdt: Add AST1030 support
Date: Thu, 31 Mar 2022 16:15:40 +0800	[thread overview]
Message-ID: <20220331081545.7140-5-jamin_lin@aspeedtech.com> (raw)
In-Reply-To: <20220331081545.7140-1-jamin_lin@aspeedtech.com>

From: Steven Lee <steven_lee@aspeedtech.com>

AST1030 wdt controller is similiar to AST2600's wdt, but it has extra
registers.
Introduce ast1030 object class and increse the number of regs(offset) of
ast1030 model.
