Subject: [PATCH 0/3] USB: host: ohci-at91: tailor power consumption
Date: Wed, 11 Sep 2019 08:41:51 +0200 [thread overview]
Message-ID: <20190911064154.28633-1-nicolas.ferre@microchip.com> (raw)
Following a set of experiments we found areas of improvement for OHCI power
consumption (and associated USB analog cells).
This enhances the shutdown of residual power consumption in case of Linux
suspend/resume and removal of the driver (when compiled as a module).
Best regards,
Nicolas
