Subject: [PATCH 5.6 23/29] nvmem: sprd: Fix the block lock operation
Date: Tue, 7 Apr 2020 12:22:20 +0200 [thread overview]
Message-ID: <20200407101454.889747276@linuxfoundation.org> (raw)
In-Reply-To: <20200407101452.046058399@linuxfoundation.org>
From: Freeman Liu <freeman.liu@unisoc.com>
commit c66ebde4d988b592e8f0008e04c47cc4950a49d3 upstream.
According to the Spreadtrum eFuse specification, we should write 0 to
the block to trigger the lock operation.
