Subject: [RESEND PATCH] soc: mediatek: PMIC wrap: Extend the waiting time to 10ms.
Date: Wed, 13 Jul 2016 11:34:28 +0800 [thread overview]
Message-ID: <1468380868-16683-1-git-send-email-henryc.chen@mediatek.com> (raw)
Read data fails sometimes because of a timeout that PMIC cannot transfer data
to PMIC wrap on time, extend the waiting time to 10ms to reduce the failed
rate.
