| * sh: Move SH-4 CPU headers down one more level.Paul Mundt2008-10-202-0/+0
| | | | | | | | | | | | | | These accidentally got placed in to cpu-sh4 instead of cpu-sh4/cpu, push them down one more level. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Only build in gpio.o when CONFIG_GENERIC_GPIO is selected.Paul Mundt2008-10-202-2/+4
| | | | | | | | | | | | | | | | | | The pinmux management is tied in to this code, while it is presently only used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions are not referenced when GENERIC_GPIO is disabled, resulting in a build failure for all of the platforms that don't select it.

| | | | | | | | | | | | | | | | | | | | SH7723 has two types of SCIF (SCIF and SCIFA). The current sh-sci driver supports only SCIFA, and calculation methods of SCBRR are different. This patch support this methods. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu.nobuhiro@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off. The ISA I/O routine wrapping remains unaffected, which remains the only special casing outside of the iomap API that boards need to think about. 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>

This implements a number of trace points: - The page fault handler / TLB miss - IPC calls - Kernel thread creation The original LTTng patch had the slow-path instrumented, which fails to account for the vast majority of events. In general placing this in the fast-path is not a huge performance hit, as we don't take page faults for kernel addresses. The other bits of interest are some of the other trap handlers, as well as the syscall entry/exit (which is better off being handled through the tracehook API). Most of the other trap handlers are corner cases where alternate means of notification exist, so there is little value in placing extra trace points in these locations. Based on top of the points provided both by the LTTng instrumentation patch as well as the patch shipping in the ST-Linux tree, albeit in a stripped down form.
