Subject: [PATCH 3/3] powerpc/83xx: Add power management support for MPC8315E-RDB boards
Date: Wed, 23 Sep 2009 23:01:22 +0400 [thread overview]
Message-ID: <20090923190122.GC19932@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20090923190041.GA18944@oksana.dev.rtsoft.ru>
- Add nodes for PMC and GTM controllers. GTM4 can be used as a wakeup
source;
- Add fsl,magic-packet properties to eTSEC nodes, i.e. wake-on-lan
support. Unlike MPC8313 processors, MPC8315 can resume from deep
sleep upon magic packet reception;
- Add proper sleep = <> properties;
- DMA and PCI share a single clock soruce, so put them into "sleep
nexus" node (the same we do for MPC8313E-RDB boards);
- I2C and Encryption core also share a single clock, so do the same:
put i2c and crypto nodes into sleep-nexus.
