From caa332336d6b2b2109894ac12e839bdc79a678b1 Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Fri, 19 Jul 2019 11:04:47 +0800 Subject: [PATCH] mmc: mtk-sd: add WATCHDOG_RESET() to prevent watchdog timeout When reading large data in once (reading 512MiB is tested on MT7623), a watchdog timeout is triggered due to watchdog not being fed. This patch adds WATCHDOG_RESET() to msdc_start_data() so the watchdog will be fed every 1024 blocks are read/written.
