978e55d2d8 bcma: prevent irq handler from firing when registered
With this patch we prevent the irq from being fired when it is
registered. The Hardware fires an IRQ when input signal XOR polarity
AND gpio mask is 1. Now we are setting polarity to a vlaue so that is
is 0 when we register it.

In addition we also set the irq mask register to 0 when the irq handler
is initialized, so all gpio irqs are masked and there will be no
unexpected irq.

17d97bad1a MIPS: bcm63xx: cpu: Replace BUG() with panic()
BUG() can be a noop if CONFIG_BUG is not selected,
leading to the following build problem on a randconfig:

arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock':
arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of
non-void function [-Werror=return-type]

We fix this problem by replacing BUG() with panic() since it's
best to handle the case of an unknown board instead of silently
returning a random clock frequency.

because devices have different amount of LEDs. And we don't want to

The BCM4706 has a problem with the CPU wait instruction. When r4k_wait

c24a8a7a99 MIPS: Netlogic: Add MSI support for XLP
Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

pci 0000:00:0a.3: no compatible bridge window for [io  0x1100-0x110f]

The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.

This patch actually reverts the change made by c5de50dada. And with this
fix, log says:

pci 0000:00:0a.3: quirk: [io  0x1000-0x103f] claimed by PIIX4 ACPI
pci 0000:00:0a.3: quirk: [io  0x1100-0x110f] claimed by PIIX4 SMB

These things may not be used but as part of platform resources are better
off to be included.

8bb5a87508 MIPS: sead3: remove chosen node
The defaults are not always applicable and it makes it hard for the bootloader
to override them. By removing it we give the bootloader full control over what
command line parameters to pass.

Without this change we will need to modify the built-in dtb to add bootloader
cmd line parameters or do some work to append them after we unflatten the device
tree.

Sead3 is a development board, that's why we want to be able to change boot
parameters on the fly from the bootloader.

44327236c3 MIPS: sead3: allow cmdline/env to change memory size using memsize param
if the user sets memsize parameter in commandline or bootloader
environment, we use it to modify the built-in dtb memory size

e95acd3d0d MIPS: BCM63XX: use linux/serial_bcm63xx.h
Update the early_printk code to include linux/serial_bcm63xx.h which
provides the definitions for the UART block registers. While at it,
remove the inclusion of serial_bcm63xx.h which was just there to allow
smooth transition.

d29e0d04b4 tty: serial: bcm63xx_uart: use linux/serial_bcm63xx.h
Now that the UART block defines have been moved to a separate file,
include that one and do not longer rely on the MIPS-specific
bcm63xx_regs.h header file.

Move the BCM63XX UART driver definitions to
include/linux/serial_bcm63xx.h such that we do not rely on the MIPS
BCM63XX code to provide these for us.

99cf979070 tty: serial: bcm63xx_uart: drop bcm_{readl,writel} macros
bcm_{readl,writel} macros expand to __raw_{readl,writel}, use these
directly such that we do not rely on the platform to provide these for
us. As a result, we no longer use bcm63xx_io.h, so remove that inclusion
too.
