Subject: [PATCH 07/10] i2c: designware-platdrv: Re-init the HW when resuming
Date: Tue, 14 Jun 2016 17:07:25 +0200 [thread overview]
Message-ID: <1465916848-8207-8-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1465916848-8207-1-git-send-email-ulf.hansson@linaro.org>
In cases when the designware specific flag "pm_runtime_disable" is set,
the HW becomes disabled during system PM suspend. Let's make sure it
becomes operational when resuming by re-initialize it again.
