can: janz-ican3: add support for CAL/CANopen firmware

2015-05-06T06:03:20+00:00

In our department we are using some older Janz ICAN3-modules in our dekstop
pcs. There we have slightly different carrier boards than the janz-cmodio
supported in the kernel sources, called CAN-PCI2 with two submodules. But the
pci configuration regions are identical. So extending the supported pci devices
to the corresponding device ids is sufficient to get the drivers working.

* The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart
  after reset. I've increased the timeout to 500ms.
* The janz_ican3 module uses the raw can services of the Janz-firmware, this
  means firmware must be ICANOS/2. Our ICAN3-modules are equipped with
  CAL/CANopen-firmware, so I must use the appropriate commands for the layer
  management services.

Te driver detects the firmware after module reset and selects the commands
matching the firmware. This affects the bus on/off-command
(ican3_set_bus_state) and the configuration of the bittiming
(ican3_set_bittiming). For better diagnostics the detected firmware string is
presented as sysfs attribute (fwinfo).

mfd: Delete non-required instances of include

2014-03-19T08:58:07+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

mfd: Remove DEFINE_PCI_DEVICE_TABLE macro

Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro
is not preferred.

mfd: core: Push irqdomain mapping out into devices

2012-09-15T21:22:04+00:00

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

mfd: Use module_pci_driver

2012-05-01T10:00:21+00:00

This patch converts the drivers in drivers/mfd/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.
