Subject: [PATCH V3 1/4] spi: sprd: Fix the wrong WDG_LOAD_VAL
Date: Thu, 26 Aug 2021 17:15:46 +0800	[thread overview]
Message-ID: <20210826091549.2138125-2-zhang.lyra@gmail.com> (raw)
In-Reply-To: <20210826091549.2138125-1-zhang.lyra@gmail.com>

From: Chunyan Zhang <chunyan.zhang@unisoc.com>

Use 50ms as default timeout value and the time clock is 32768HZ.
The original value of WDG_LOAD_VAL is not correct, so this patch
fixes it.

Fixes: ac1775012058 ("spi: sprd: Add the support of restarting the system")
