2012-05-15MIPS: ath79: remove ar724x_pci_add_data functionGabor Juhos1-7/+0
The variables set by this function are not used anymore. Remove the function and the relevant variables as well. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3501/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-05-15MIPS: ath79: allow to use board specific pci_plat_dev_init functionsGabor Juhos1-1/+12

However it makes no sense to use that function for every board, especially when the board does not needs to set the platform_data field of any PCI device. The patch allows the board setup code to specify a board specific function if that is required.

2012-05-15MIPS: ath79: get rid of some ifdefs in mach-ubnt-xm.cGabor Juhos1-11/+12
Remove a superfluous ifdef around an include. Also reorganize the board setup code a bit, so another ifdef can be removed.

2012-05-15MIPS: ath79: fix a wrong IRQ numberGabor Juhos1-2/+3
The Ubiquiti XM board setup code uses an invalid IRQ number, because it if above of NR_IRQS. This leads to failed 'request_irq' calls: ath9k 0000:00:00.0: request_irq failed ath9k: probe of 0000:00:00.0 failed with error -22 Preserve some IRQ numbers for the built-in IRQ controller of PCI host controllers in the AR71XX/AR724X SoCs, and use the correct IRQ number in the board setup code.

2012-05-15MIPS: ath79: replace ath724x to ar724xGabor Juhos1-2/+2
Replace the 'ath724x' to 'ar724x' in function, variable and structure names to reflect the name of the real SoC.

2012-05-15MIPS: ath79: add a common PCI registration functionGabor Juhos1-0/+1
The current code unconditionally registers the AR724X specific PCI controller, even if the kernel is running on a different SoC. Add a common function for PCI controller registration, and only register the AR724X PCI controller if the kernel is running on an AR724X SoC.
