Drop support for Renesas H8/300 (h8300) architecture

2013-09-17T01:19:04+00:00

H8/300 has been dead for several years, and the kernel for it has not compiled for ages. Drop support for it. Cc: Yoshinori Sato Acked-by: Greg Kroah-Hartman Signed-off-by: Guenter Roeck

serial: sh-sci: HSCIF support

2013-06-17T09:09:53+00:00

Adds support for "High Speed Serial Communications Interface with FIFO", essentially a SCIF with 128-byte FIFOs and more accurate baud rate generator. Signed-off-by: Ulrich Hecht Acked-by: Paul Mundt Acked-by: Greg Kroah-Hartman Signed-off-by: Simon Horman

serial: sh-sci: modify sci_break_ctl()

2012-04-09T08:39:34+00:00

SCIF modules which have SCSPTR can output the break signal. Now that we have a way of determining port features/capabilities, add trivial break control via SCSPTR support. Tested on sh7757lcr. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Paul Mundt

serial: sh-sci: Handle GPIO function requests.

2011-12-02T11:09:48+00:00

This adds initial support for requesting the various GPIO functions necessary for certain ports. This just plugs in dumb request/free logic, but serves as a building block for migrating off of the ->init_pins mess to a wholly gpiolib backed solution (primarily parts with external RTS/CTS pins, but will also allow us to clean up RXD pin testing).

serial: sh-sci: per-port modem control.

2011-12-02T08:44:50+00:00

The bulk of the ports do not support any sort of modem control, so blindly twiddling the MCE bit doesn't accomplish much. We now require ports to manually specify which line supports modem control signals. While at it, tidy up the RTS/CTSIO handling in SCSPTR parts so it's a bit more obvious what's going on (and without clobbering other configurations in the process). Signed-off-by: Paul Mundt

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

2011-11-04T13:33:30+00:00

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

2011-09-19T03:09:17+00:00

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.

2011-06-28T06:25:36+00:00

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.

2011-06-14T03:40:19+00:00

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.
