* serial: sh-sci: fix handling of SCIFB sh-mobile portsGuennadi Liakhovetski2010-05-241-6/+23
| | | | | | | | SCIFB ports have a slightly different register layout and a different FIFO size from SCIFA ports, in DMA mode they have to be treated just like SCIFA. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* serial: sh-sci: fix SH-Mobile SH breakageMagnus Damm2010-03-231-7/+22
| | | | | | | | | | | | | | | | | The follwing commit breaks SH-Mobile on non-ARM platforms: "8a77b8d serial: sh-sci: Support ARM-based SH-Mobile CPUs." The commit assumed that CONFIG_ARCH_SHMOBILE only was set on ARM platforms, but it turns out that this kconfig is also set by all SH-based SoCs. Sh7724 and other older SH-Mobile SoCs are all broken without this fix. This patch converts the "defined(CONFIG_ARCH_SHMOBILE)" into one "defined()" per SoC model - similar to existing SH code.

* serial: sh-sci: Support ARM-based SH-Mobile CPUs.Magnus Damm2010-02-081-8/+14
| | | | | | | | | | Add support for ARM-based SH-Mobile CPUs to the sh-sci driver. Also remove the SCLSR register that is missing on sh772x, sh7705 and SH-Mobile. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: remove SCIF code in sci_rxd_in()Magnus Damm2010-02-081-219/+1
| | | | | | | | | | | | Since sci_rxd_in() is used by SCI only, clean up the header file by killing off code dealing with SCIF ports and their register definitions. Also introduce a default sci_rxd_in() function which can be shared by all SCIF-only processors. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: Convert tremaining ctrl_xxx I/O routines to __raw_xxx.Paul Mundt2009-12-241-59/+59
| | | | | | | | | ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard API that accomplishes the same thing. As such, this converts the remaining sh-sci straggles over, which enables the driver to be wired up for ARM SH-Mobile CPUs as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: Depend on HAVE_CLK unconditionally.Paul Mundt2009-11-251-1/+1
| | | | | | | | | | | | | The sh-sci code conditionalized the clock framework support in order to give the other platforms a chance to catch up. sh64 supported this some time ago and the forthcoming ARM changes handle this as well, this leaves h8300 as the odd one out. H8300 has had since 2.5 to merge it's sh-sci support upstream, and has yet to do so. At this point I will no longer be holding back the driver to support an unreponsive architecture, 7 years is quite enough of a grace period. Support is easily implemented on the architecture if and when it ever decides to merge its changes upstream. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

|/ | | | | | | | | | | | | | Presently this is conditionalized on sh, and disabled for sh64. Now that SH-5 ties in to the clock framework, the sh64 exception can be dropped. Additionally, ARM will want to use the same hooks once SH-Mobile G3 grows clock framework support, so switch these paths over to HAVE_CLK now. Once the H8 and ARM sh-sci users hook up HAVE_CLK, the driver can be switched over to having an outright dependency on it and the ifdefs can go away. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
