[PATCH 1/4][Version 3] MPC5121 Update MPC5121ADS device tree
John Rigby
jrigby at freescale.com
Thu Jul 10 06:54:01 EST 2008
Current device tree is only bare bones. This patch
adds nodes to make it a complete tree for MPC5121ads.
Added nodes include:
mbx - opengl coprocessor
nfc - nand flash controller
cpld-pic - on board cpld
rtc
clock - clock control
pmc - power management control
gpio
mscan - can module
i2c
axe - audio coprocessor
display - display interface unit
mdio
ethernet
usb
ioctl - pin config
pata
ac97 - PSC configured as AC97
pscfifo - psc fifo configuration
dma
pci
Fix typo in header changing MDS to ADS.
Add a compatible property of the form "fsl,mpc5121-..."
to nodes missing one.
Changed localbus compatible to fsl,mpc5121-localbus, this does
not break anything because the only code that uses it finds it
via the node name, not compatible.
