serial: sh-sci: Reorder the SCxTDR write after the TDxE clear.

2008-11-13T08:46:06Z

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR write. While on hardware it can be gauranteed that the read-and-clear will happen prior to the character being written out, no such assumption can be made under emulation. As this path happens with IRQs off and the hardware itself doesn't care about the ordering, move the SCxTDR write until after the read-and-clear.

serial: sh-sci: fix cannot work SH7723 SCIFA

2008-11-12T03:29:56Z

SH7723 has SCIFA. This module is similer SCI register map, but it has FIFO. So this patch adds new type(PORT_SCIFA) and change some type checking. Signed-off-by: Yoshihiro Shimoda Signed-off-by: Paul Mundt

sh: Fix up the shared IRQ demuxer's control bit testing logic.

2008-10-31T07:10:23Z

Correct the interrupt handler in sh4 serial device, return the correct value and check for what is anabled in the SCSCR register. The sh7722 is broken just sending a break using minicom. Signed-off-by: Michael Trimarchi Signed-off-by: Paul Mundt

Merge branch 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

2008-10-20T20:23:01Z

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu and x86/uv. The sparseirq branch is just preliminary groundwork: no sparse IRQs are actually implemented by this tree anymore - just the new APIs are added while keeping the old way intact as well (the new APIs map 1:1 to irq_desc[]). The 'real' sparse IRQ support will then be a relatively small patch ontop of this - with a v2.6.29 merge target. * 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (178 commits) genirq: improve include files intr_remapping: fix typo io_apic: make irq_mis_count available on 64-bit too genirq: fix name space collisions of nr_irqs in arch/* genirq: fix name space collision of nr_irqs in autoprobe.c genirq: use iterators for irq_desc loops proc: fixup irq iterator genirq: add reverse iterator for irq_desc x86: move ack_bad_irq() to irq.c x86: unify show_interrupts() and proc helpers x86: cleanup show_interrupts genirq: cleanup the sparseirq modifications genirq: remove artifacts from sparseirq removal genirq: revert dynarray genirq: remove irq_to_desc_alloc genirq: remove sparse irq code genirq: use inline function for irq_to_desc genirq: consolidate nr_irqs and for_each_irq_desc() x86: remove sparse irq from Kconfig genirq: define nr_irqs for architectures with GENERIC_HARDIRQS=n ...

serial: sh-sci: Kill off all of the SCI/SCIF special casing.

2008-10-02T10:47:12Z

This was added at a time when the compiler did a less than stellar job of optimizing out dead code. These days this tends to be less of a concern, so kill it all off. Signed-off-by: Paul Mundt

serial: sh-sci: Dynamic clock management depends on HAVE_CLK.

2008-10-02T10:09:13Z

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

serial: sh-sci: Handle the general UPF_IOREMAP case.

2008-10-01T06:46:58Z

Presently we don't do much with UPF_IOREMAP other than special case it for SH-5's onchip_remap() on the early console. Tie this in generically for platforms that need the remap. Signed-off-by: Paul Mundt
