Subject: [PATCH v2 14/15] usb: dwc2: Update dwc2_handle_usb_suspend_intr function.
Date: Fri, 16 Apr 2021 16:48:34 +0400 [thread overview]
Message-ID: <20210416124835.9F257A005D@mailhost.synopsys.com> (raw)
In-Reply-To: <cover.1618464534.git.Arthur.Petrosyan@synopsys.com>
To avoid working in two modes (partial power down
and hibernation) changed conditions for entering
partial power down or hibernation.
Instead of checking hw_params.power_optimized and
hw_params.hibernation now checking power_down
param which already set to one of the options
(Hibernation or Partial Power Down) based on
OTG_EN_PWROPT.
