This patch adds gpio code together with the pinmux table parser. In the future we should optimize this and switch back to gpiolib. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul 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: NPaul 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: NPaul Mundt <lethal@linux-sh.org>

This provides a workaround for users of sh_mobile_lcdcfb that don't define HAVE_CLK and have otherwise sane clock initialization. At the same time, move the sh_mobile_lcdc.h header to include/video/. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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: NPaul Mundt <lethal@linux-sh.org>

This implements a few trace points across events that are deemed interesting. 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.

This follows the powerpc commit f6a61680 '[POWERPC] Fix kernel stack allocation alignment'. SH has traditionally forced the thread order to be relative to the page size, so there were never any situations where the same bug was triggered by slub. Regardless, the usage of > 8kB stacks for the larger page sizes is overkill, so we switch to using slab allocations there, as per the powerpc change. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This combination triggers a divide by zero in kernel/fork.c when calculating the initial max_threads value: max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE); Simply disable 4K stacks on 64kB PAGE_SIZE to work around this, as it's not a terribly useful combination to begin with.

These have been using overrides for ELF_CORE_COPY_TASK_REGS and ELF_CORE_COPY_FPREGS while the generic versions can be used instead. Presently the pt_regs are also duplicated across elf_core_copy_regs() and elf_core_copy_task_regs(), this switches to simply copying out through elf_core_copy_regs() instead.
