Subject: [PATCH] i2c: rk3x: keep i2c irq ON in suspend
Date: Mon, 5 Dec 2016 16:02:59 +0800 [thread overview]
Message-ID: <1480924979-13450-1-git-send-email-david.wu@rock-chips.com> (raw)
During suspend there may still be some i2c access happening.
And if we don't keep i2c irq ON, there may be i2c access timeout if
i2c is in irq mode of operation.
