Subject: [PATCH v2 0/2] ARM: ohci-at91: Add support to forcibly suspend ports while sleep
Date: Wed, 1 Jun 2016 12:29:58 +0800 [thread overview]
Message-ID: <1464755400-6825-1-git-send-email-wenyou.yang@atmel.com> (raw)
To save the power consumption, add a new compatible to support forcibly
suspend the USB PORTA/B/C via OHCI Interrupt Configuration SFR Register.
Changes in v2:
- Add compatible to support forcibly suspend the ports.
- Add soc/at91/at91_sfr.h to accommodate the defines.
- Add error checking for .sfr_regmap.
- Remove unnecessary regmap_read() statement.
- Use the new compatible for ohci-node.
