Subject: [PATCH v8 3/5] pinctrl: Ingenic: Introduce reg_offset and use it instead hard code.
Date: Mon, 16 Dec 2019 00:21:02 +0800	[thread overview]
Message-ID: <1576426864-35348-5-git-send-email-zhouyanjie@wanyeetech.com> (raw)
In-Reply-To: <1576426864-35348-1-git-send-email-zhouyanjie@wanyeetech.com>

Introduce "reg_offset", use it instead hard code "0x100",
it will also be used for subsequent X1830 pinctrl driver.
