Subject[PATCH 5/7] pinctrl: aspeed: Move aspeed_pin_config_map to separate source file
Date
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.
