* serial: sh-sci: Move overrun_bit and error_mask fields out of pdataLaurent Pinchart2013-12-241-1/+1
| | | | | | | | | | None of the fields is ever set by board code, and both of them are set in the driver at probe time. Move them out of struct plat_sci_port to struct sci_port.

* serial: sh-sci: remove obsolete Kconfig macrosPaul Bolle2013-03-251-2/+0
| | | | | | | | Support for SH7367 and SH7377 got removed in v3.8. Now remove their last Kconfig macros. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* serial: sh-sci: use serial_port_in/out vs sci_in/out.Paul Mundt2012-03-301-4/+4
| | | | | | | | Follows the 8250 change for pretty much the same rationale. See commit "serial: use serial_port_in/out vs serial_in/out in 8250". Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: R-Mobile A1 support.Kuninori Morimoto2011-11-111-1/+3
| | | | | | | | | | This adds preliminary support for the R8A7740 (R-Mobile A1) CPU Timer, serial, gic, clock are supported at this point. This patch is based on v0.1 manual Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: FIFO sizing helper consolidation.Paul Mundt2011-06-141-20/+0
| | | | | | | | | | | | | | | | This consolidates all of the TX/RX fill/room nonsense in to a single set of fairly heavyweight definitions. The implementation goes in descending order of complexity, testing the register map for capabilities until we run out of options and do it the legacy SCI way. Masks are derived directly from the per-port FIFO size, meaning that platforms with FIFO sizes not matching the standard port types will still need to manually fix them up. This also fixes up a number of issues such as tx_empty being completely bogus for SCI and IrDA ports, some ports using masks smaller or greater than their FIFO size, and so forth.

* serial: sh-sci: Abstract register maps.Paul Mundt2011-06-141-222/+0
| | | | | | | | | | | | | | | 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.Paul Mundt2011-06-081-29/+0
| | | | | | | | | | | | | | | 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.Paul Mundt2011-06-081-50/+2
| | | | | | | | | 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.

* serial: sh-sci: Kill off bitrotted H8/300 support.Paul Mundt2011-06-061-92/+11
| | | | | | | | | h8300 has never been updated upstream to support the conversion to the driver model (which happened mid-2.5), and it doesn't seem likely that it ever will. Kill off the remaining bitrotted support to reduce the maintenance burden going forward. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* tty: move drivers/serial/ to drivers/tty/serial/Greg Kroah-Hartman2011-01-131-0/+660
The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall. This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.
