Subject: [PATCH 01/14] nvmem: imx: ocotp: add i.MX8MP support
Date: Tue, 10 Mar 2020 13:22:44 +0000	[thread overview]
Message-ID: <20200310132257.23358-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20200310132257.23358-1-srinivas.kandagatla@linaro.org>

From: Peng Fan <peng.fan@nxp.com>

i.MX8MP has 96 banks with each bank 4 words. And it has different
ctrl register layout, so add new macros for that.
