Subject: [PATCH 1/4] nvmem: imx: scu: fix write SIP
Date: Thu,  9 Jan 2020 10:40:14 +0000
Message-ID: <20200109104017.6249-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20200109104017.6249-1-srinivas.kandagatla@linaro.org>

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

SIP number 0xC200000A is for reading, 0xC200000B is for writing.
And the following two args for write are word index, data to write.

Fixes: 885ce72a09d0 ("nvmem: imx: scu: support write")
