[PATCH 0/2] DA923RC: add PCI support

[Renaud Barbier]

This patch set adds the fsl,mpic node frequency property
needed by Linux version 3.x for the PCI driver to function.
Also it was noticed that the board device reset was held
low preventing full probing of the PCI bus.

[PATCH 1/2] ppc: mpc85xx: add fsl,mpic node frequency property

[Renaud Barbier]

The clock frequency property of the device tree node fsl,mpic is
added as it is needed by the PCI driver to function in newer
Linux version.

[PATCH 2/2] ppc: DA923RC: update board initialisation

[Renaud Barbier]

Pull the board device reset GPIO pin high as this prevents
PCI bus probing.
The function da923rc_board_init_r is called at the postcore
initcall level so that the udelay function can take advantage
of the core initialisation.
