2013-01-14bcma: fix bcm4716/bcm4748 i2s irqflagNathan Hintz
The default irqflag assignment for the I2S core on some Broadcom 4716/4748 devices is invalid and needs to be corrected (from the Broadcom SDK). Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> Acked-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-01-11bcma: return the mips irq number in bcma_core_irqNathan Hintz
The irq signal numbers that are send by the cpu are increased by 2 from the number programmed into the mips core by bcma. Return the irq number on which the irqs are send in bcma_core_irq() now.

2013-01-07bcma: mips: show also disabled IRQsHauke Mehrtens
Some cores do not have a IRQ assigned and some do not support when an IRQ is assigned to them, this is now handled and printed out in the code. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-01-07bcma: mips: explicit assign IRQ numbersHauke Mehrtens
The assignment of the IRQs to the cores of the chips by iterating over the cores is complicated and causes problems with SoC like the BCM4706 with two GMAC core where just one should get a dedicated IRQ number. Now the code assigns the same IRQs to the cores as the code from the Broadcom SDK does. If the SoC is not know the current assigned IRQs are only read out and an error message is printed.

2012-12-10bcma: mips: fix clearing device IRQRafał Miłecki
We were using wrong IRQ number so clearing wasn't working at all. Depending on a platform this could result in a one device having two interrupts assigned. On BCM4706 this resulted in all IRQs being broken.

2012-10-19bcma: just do the necessary things in early register on SoCsHauke Mehrtens
Some parts of the initialization for chip common and the pcie core are accessing the sprom struct, but it is not initialized at that stage. Just do the necessary thing in the early register on SoCs and not the complete initialization to read out the nvram from the flash chip. After it is possible to read out the nvram, the sprom should be parsed from it and the full initialization of the cores should be run.

2012-07-26bcma: fix regression in interrupt assignment on mipsHauke Mehrtens
The wrong interrupts where assigned to the cores in bcma_core_mips_init(). This caused at least my serial console not to response to any input. This was caused by this patch which changed the order of the cores in the list: commit c334e25c9f3a95f2bd6b79fedc5170f17245b1c7 Author: Rafał Miłecki <zajec5@gmail.com> Date: Wed Jul 11 12:37:00 2012 +0200 bcma: add new cores at the end of list This should be fixed properly later so that the correct interrupt numbers are assigned to the cores independently from the ordering of the list. This patch restores the old behavior again. I will look into the problem more deeply later. I also changed the order of the list with the cores and their assigned interrupt number which gets printed to the log. Now they are printed in the same order like all the other lists of cores and like it was done before the patch which changed the order.

2012-07-09bcma: use custom printing functionsRafał Miłecki
Having bus number printed makes it much easier to anaylze logs on systems with more buses. For example Netgear WNDR4500 has 3 AMBA buses in total, which makes standard log really messy. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
