[PATCH v2 10/24] dts: mpc512x: add clock specs for client lookups
Gerhard Sittig

Fri Jul 19 03:00:41 EST 2013
this addresses the client side of device tree based clock lookups:
add clock specifiers to the mbx, nfc, mscan, sdhc, i2c, axe, diu,
viu, mdio, fec, usb, pata, psc, psc fifo, and pci nodes in the
shared mpc5121.dtsi include
these specs map 'clock-names' encoded in drivers to their respective
'struct clk' items in the platform's clock driver; some drivers
still need to learn how to lookup OF clocks, other drivers will
transparently probe successfully on MPC512x as well (sdhc)
few 'clock-names' (nfc, viu) use strings that are encoded in their
respective drivers to keep up compatibility, an alternative approach
would be to register clkdev items in the platform's clock driver for
the migration period
