[POWERPC] Add Marvell mv64x60 PCI bridge support

2007-05-12T01:32:50+00:00

This patch adds PCI bridge support for the Marvell mv64x60 chip.
We also provide the ability to read/write the mv64x60 hotswap
register via sysfs if the hs_reg_valid property is set in the
device tree.

[POWERPC] Create Marvell mv64x60 MPSC (serial) platform_data

2007-05-12T01:32:49+00:00

This patch creates platform_device entries for the Marvell mv64x60
MPSC (multi-protocol serial controller) ports, based on information
contained in the device tree.

This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures.  Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.

[POWERPC] Add interrupt support for Marvell mv64x60 chips

2007-05-12T01:32:49+00:00

There are 3 interrupt groups each with its own status/mask registers.
We use a separate struct irq_chip for each interrupt group and handle
interrupts in two stages or levels: level 1 selects the appropriate
struct irq_chip, and level 2 selects individual interrupts within
that irq_chip.

[POWERPC] Abolish powerpc_flash_init()

2007-05-08T05:09:26+00:00

powerpc_flash_init() implements a broken way of probing for flash
devices supported by the physmap_of driver.  It finds all nodes in the
device tree with device_type=="rom" and instantiates of_platform
devices for them.  This is fundamentally incompatible with the normal
and correct way of probing for of_platform_bus_probe().  Platforms
which relied on powerpc_flash_init()s behaviour (none are in-tree)
will have to update their platform probing code to correctly probe
busses containing flash devices.

[POWERPC] MPIC U3/U4 MSI backend

2007-05-08T03:46:48+00:00

MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me.
This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5.

If we find a U3/U4 then we enable this backend, ie. take over the ppc_md
MSI hooks. We might need more elaborate logic in future to decide which
backend is enabled.

We need our own irq_chip so that we can do MSI masking/unmasking on
the device itself. We also need to mask explicitly on shutdown to make
sure we don't get bitten by lazy-disable semantics.

[POWERPC] MPIC MSI allocator

2007-05-08T03:43:48+00:00

To support MSI on MPIC we need a way to reserve and allocate hardware irq
numbers, this patch implements an allocator for that purpose.

New firmware platforms must define a "msi-available-ranges" property on their
MPIC node for MSI to work. For U3/U4 we do a best-guess setup.

[POWERPC] Add arch/powerpc driver for UIC, PPC4xx interrupt controller

2007-04-24T11:32:01+00:00

This patch adds a driver to arch/powerpc/sysdev for the UIC, the
on-chip interrupt controller from IBM/AMCC 4xx chips.  It uses the new
irq host mapping infrastructure.

[POWERPC] 86xx/85xx: Move 8641 PCI-Express to arch/powerpc/sysdev/fsl_pcie.c.

2007-03-26T22:03:25+00:00

This move sets the stage for the use of generic PCI Express
code in 85xx and 86xx parts from FSL.  Subsequent patches
for 8548 and 8544 will be able to use this shared code.

[POWERPC] Generic time suspend/resume code

2007-03-26T02:35:14+00:00

This removes the time suspend/restore code that was done through
a PMU notifier in arch/platforms/powermac/time.c.

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys
device and handles time of day suspend/resume through that.

This should probably be replaced by using the generic RTC framework
but for now it gets rid of the arcane powermac specific hack.

[POWERPC] Add PMI driver for cell blade

2007-02-16T03:00:19+00:00

This adds driver code for the PMI device found in future IBM products.
PMI stands for "Platform Management Interrupt" and is a way to
communicate with the BMC (Baseboard Management Controller).
It provides bidirectional communication with a low latency.
