serial: sh-sci: Fix up SH-2A SCIF support.

2011-11-04T13:33:30Z

This fixes up support for SH-2(A) SCIFs by introducing a new regtype. As expected, it's close to the SH-4A SCIF with fifodata, but still different enough to warrant its own type. Fixes up a number of FIFO overflows and similar for both SH7203/SH7264. Signed-off-by: Phil Edworthy Tested-by: Federico Fuga Signed-off-by: Paul Mundt

serial: sh-sci: don't filter on DMA device, use only channel ID

2011-09-19T03:09:17Z

On some sh-mobile systems there are more than one DMA controllers, that can be used for serial ports. Specifying a DMA device in sh-sci platform data unnecessarily restricts the driver to only use one DMA controller.

serial: sh-sci: Fix up pretty name printing for port IRQs.

2011-06-28T06:25:36Z

Presently these were all using the same static string with no regard to dev_name() and the like. This implements a bit of rework to name the IRQ dynamically, as it should have been doing all along anyways. Signed-off-by: Paul Mundt

serial: sh-sci: Abstract register maps.

2011-06-14T03:40:19Z

This takes a bit of a sledgehammer to the horribly CPU subtype ifdef-ridden header and abstracts all of the different register layouts in to distinct types which in turn can be overriden on a per-port basis, or permitted to default to the map matching the port type at probe time. In the process this ultimately fixes up inumerable bugs with mismatches on various CPU types (particularly the legacy ones that were obviously broken years ago and no one noticed) and provides a more tightly coupled and consolidated platform for extending and implementing generic features.

serial: sh-sci: Consolidate RXD pin handling.

2011-06-08T09:51:32Z

Non-SCI parts do not have the special port reg necessary for cases where the RX and SCI pins are muxed and need to be manually polled, so these like always fall back on the normal FIFO processing paths. SH7760 is in a class in and of itself with regards to mapping its SIM card interface via the SCI port class despite not having any of the RXD lines wired up and so implicitly behaving more like a SCIF in this regard. Out of the other CPUs, some support the port check via the same block while others do it through an external SuperI/O, so it's not even possible to perform the check relative to the ioremapped cookie offset, so the separate read semantics are preserved here, too.

serial: sh-sci: Generalize overrun handling.

2011-06-08T09:19:37Z

This consolidates all of the broken out overrun handling and ensures that we have sensible defaults per-port type, in addition to making sure that overruns are flagged appropriately in the error mask for parts that haven't explicitly disabled support for it. Signed-off-by: Paul Mundt

serial: sh-sci: Kill off some DMA ifdeffery.

2011-01-19T06:37:31Z

There's nothing worth hiding under the ifdef in the platform DMA definitions, and we certainly don't want board code adding this in to their platform data definitions, so we always expose the slave rx/tx and device pointer members instead. Signed-off-by: Paul Mundt

serial: sh-sci: Provide a helper for muxed IRQs.

2011-01-19T05:37:14Z

All of the muxed IRQs presently populate the IRQ array verbosely, this simply provides a trivial helper to do it for them. Signed-off-by: Paul Mundt

serial: sh-sci: Kill off unused membase kludge.

2011-01-19T05:18:06Z

All users of the platform port data specify a mapbase where the driver later derives the membase from. Now that UPF flags are taken in to account for generic ioremapping we can kill off the port-specific membase clobbering and simply use the generic paths. This derives from a time when sh64 was not capable of using the generic ioremap implementation and had employed early bolted DTLB mappings for port access, which is no longer an issue.
