Subject: [PATCH 5/7] pinctrl: aspeed: Move aspeed_pin_config_map to separate source file
Date: Mon,  2 Dec 2019 16:44:30 +1030	[thread overview]
Message-ID: <20191202061432.3996-6-andrew@aj.id.au> (raw)
In-Reply-To: <20191202061432.3996-1-andrew@aj.id.au>

From: Johnny Huang <johnny_huang@aspeedtech.com>

The AST2600 pinconf differs from the 2400 and 2500, aspeed_pin_config_map
should define separately, and add @confmaps and @nconfmaps to
aspeed_pinctrl_data structure for that change.
