* serial: sh-sci: Kill off some DMA ifdeffery.Paul Mundt2011-01-191-4/+2
| | | | | | | | | 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.

* serial: sh-sci: Provide a helper for muxed IRQs.Paul Mundt2011-01-191-0/+8
| | | | | | | 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 <lethal@linux-sh.org>
* serial: sh-sci: Kill off unused membase kludge.Paul Mundt2011-01-191-1/+0
| | | | | | | | | | | | | 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.

* serial: sh-sci: Kill off unused clock string.Paul Mundt2011-01-191-1/+0
| | | | | | | Now that the clock string isn't used by the driver anymore, kill it off from the platform structure. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * serial: sh-sci: fix up serial DMA build.Paul Mundt2010-05-251-3/+1

| * dmaengine: shdma: Remove sh_dmae_slave_chan_id enumMagnus Damm2010-03-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the sh_dmae_slave_chan_id enum with an unsigned int. The purpose of this chainge is to make it possible to separate the slave id enums from the dmaengine header. The slave id enums varies with processor model, so in the future it makes sense to put these in the processor specific headers together with the pinmux enums.

| * serial: sh-sci: Fix build failure for non-sh architectures.Peter Huewe2010-03-101-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a build failure for various arm based defconfigs [1][2][3] and maybe other architectures/configs. The build failure was introduced by the sh specific patch [4] "serial: sh-sci: Add DMA support" by Guennadi Liakhovetski Patch against linux-next of 20100309 References: [1] http://kisskb.ellerman.id.au/kisskb/buildresult/2248992/ [2] http://kisskb.ellerman.id.au/kisskb/buildresult/2248996/ [3] http://kisskb.ellerman.id.au/kisskb/buildresult/2248998/ [4] http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=73a19e4c0301908ce6346715fd08a74308451f5a Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | serial: sh-sci: Move SCBRR calculation algo in to platform data.Paul Mundt2009-06-241-0/+9
| | | | | | | | | | | | | | | | This permits each port to select its own SCBRR calculation algorithm, rather than having it all ifdef'ed in the header. There are presently only 5 different variations that all parts fall under. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* serial: Move asm-sh/sci.h to linux/serial_sci.h.Paul Mundt2008-02-261-0/+32
This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
