2012-11-21staging: comedi: me_daq: remove broken workaround for PLX bugIan Abbott
The PLX PCI 9050 interface chip has a bug where its local configuration registers accessible through PCI BAR 0 and/or PCI BAR 1 (depending on settings loaded from a serial EEPROM or local bus processor) are unreadable (always read 0 instead of the true register values) if the base address starts on an odd multiple of 0x80 (i.e. has bit 7 set to 1). The "me_daq" driver attempts to work around this by writing to the PCI config space to swap the addresses assigned to PCI BAR 0 and PCI BAR 5 (which has been initially configured by serial EEPROM load as a spare region of the same length as the PCI BAR 0 region). (If the PCI BAR 5 region is absent, it attempts to reduce the PCI BAR 0 address by 0x80, which is likely to cause havoc for some other device, but that case shouldn't be reachable in practice.) The workaround in the driver is ineffective because it has already ioremapped the memory from `pci_resource_start(pcidev, 0)` *before* it does the workaround, so after swapping PCI BAR 0 and PCI BAR 5, this memory will end up accessing whatever onboard registers PCI BAR 5 was linked to instead of the local configuration registers. It also leaves the addresses in the physical PCI BAR registers set differently to the resource start addresses recorded in the `struct pci_dev`. The workaround could be fixed by ioremapping `pci_resource_start(pcidev, 5)` if the PCI BAR addresses were physically swapped (and the fallback workaround of subtracting 0x80 from the base address should really be removed altogether). However, it's not really worth it. This sort of thing should be worked around in "drivers/pci/quirks.c" by ensuring that PCI BAR 0 and/or PCI BAR 1 do not end up on an odd multiple of 0x80 bytes.

2012-11-15staging: comedi: use inlines for PCI/USB auto configIan Abbott
Apart from the somewhat unnecessary `BUG_ON()` calls, `comedi_pci_auto_config()` and `comedi_usb_auto_config()` are just one-line wrappers around `comedi_auto_config()`, and `comedi_pci_auto_unconfig()` and `comedi_usb_auto_unconfig()` are just one-line wrappers around `comedi_auto_unconfig()`. Convert them to inline functions and remove the `BUG_ON()` calls. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-15staging: comedi: remove attach_pci and attach_usb handlersIan Abbott
No comedi drivers set the `attach_pci()` or `attach_usb()` handlers in their `struct comedi_driver` any longer as they have all been replaced with an `auto_attach()` handler. Also, no code calls the `attach_pci()` or `attach_usb()` handlers any longer. Remove them from `struct comedi_driver`.

2012-11-15staging: comedi: simplify comedi_auto_attach()Ian Abbott
`comedi_auto_config()` just calls internal function `comedi_auto_config_helper()`, passing it a wrapper function `comedi_auto_config_wrapper()` to handle the specifics of checking and calling the low-level comedi driver's `auto_attach()` handler. Since there are no other callers of `comedi_auto_config_helper()` or `comedi_auto_config_wrapper()`, combine everything into the single exported function `comedi_auto_config()`. Change the ordering of the check for existence of the low-level comedi driver's `auto_attach()` handler and the allocation of the comedi minor device number. This means the log message warning of the absence of the handler now has to be refer to the hardware device instead of the not-yet-allocated comedi device.

2012-11-15staging: comedi: don't check driver->auto_attachIan Abbott
There is no need for `comedi_pci_auto_config()` and `comedi_usb_auto_config()` to check that `driver->auto_attach` is non-null before calling `comedi_auto_attach()` as this check is done by `comedi_auto_config()` itself (actually by `comedi_auto_config_wrapper()`). Remove the unnecessary checks. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-15staging: comedi: don't call attach_usb handlerIan Abbott
All the Comedi drivers that call `comedi_usb_auto_config()` have replaced the `attach_usb()` handler in their `struct comedi_driver` with a `auto_attach()` handler, so there is no need to check for the existence of the `attach_usb()` handler any more. Remove this check and the code that calls it. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-11-15staging: comedi: remove old auto-configIan Abbott
All the Comedi drivers that call `comedi_pci_auto_config()` or `comedi_usb_auto_config()` define a `auto_attach()` handler in their `struct comedi_driver`. There is no need to fall back to abusing the `attach()` handler any more, so remove the code that supports that.

2012-11-15staging: comedi: define operations for INSN_CONFIG_DIGITAL_TRIGIan Abbott
The 'addi_apci_1032' driver recently started supporting the `INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other drivers were using it before, there was no existing practice of how the instruction should look. Define the format to be something a bit more configurable. In particular, a subdevice might have more than one trigger requiring an ID and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have more than 32 inputs, and a trigger might need several `INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure completely (if there are more than 32 inputs or if it uses a combination of edge-triggered and level-triggered inputs).

2012-11-15staging: comedi: check data length for INSN_CONFIG_DIGITAL_TRIGIan Abbott
The newly defined format for the `INSN_CONFIG_DIGITAL_TRIG` configuration instruction expects 6 data values.

2012-11-15staging: comedi: addi_apci_1032: conform to new INSN_CONFIG_DIGITAL_TRIGIan Abbott
Conform to the new definition of the `INSN_CONFIG_DIGITAL_TRIG` configuration instruction. Return an error if the 'trigger number' in `data[1]` is non-zero or if the configuration operation in `data[2]` is not supported. Deal with the 'left-shift' amount in `data[3]`. The trigger's input channels can only be configured as a set of rising and falling edges ('OR' mode) or as a set of high and low levels ('AND' mode). Preserve the old input channels to the right of the 'left-shift' value except when switching modes. (The 'left-shift' support is a bit of an overkill for this driver since the trigger only has 16 input channels.)
