  • a6472533e   ARM: OMAP: gpio lockdep updates ... Browse Code »

    Fix some spinlock issues reported by lockdep: since the gpio bank
    locks can be aquired in both irq and non-irq contexts, they need
    to be consistent about always using the irq-safe variants.

    In mainline, the "old style" I2C registration was only removed for
    OMAP2, leading to init-time bugs (regressions) like:

    sysfs: duplicate filename 'i2c_omap.1' can not be created

    kobject_add_internal failed for i2c_omap.1 with -EEXIST, don't try to register things with the same name in the same directory.

    The fix is obvious: remove the old init code, it's no longer needed.

    Remove false lockdep warnings about lock recursion when declaring
    IRQs as being wake-capable, by marking putting GPIO irq_desc locks
    into their own class.

    (Thanks to Peter Zijlstra for helping track down such a small
    fix to this problem.)

    This makes parameter passing to DMA handlers uniform between non-chained
    and chained transfers and makes debugging easier. Additional data like
    chain_id can be always passed to handlers via callback data if needed.

  • 72a7fe396   Introduce flags for reserve_bootmem() ... Browse Code »

    This patchset adds a flags variable to reserve_bootmem() and uses the
    BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
    between crashkernel area and already used memory.

    This patch:

    Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
    If that flag is set, the function returns with -EBUSY if the memory already
    has been reserved in the past. This is to avoid conflicts.

    Because that code runs before SMP initialisation, there's no race condition
    inside reserve_bootmem_core().

  • e7b3dc7ef   [NET] smc91x: Make smc91x use IRQ resource trigger flags ... Browse Code »

    smc91x is shared between many different platforms. Each platform needs
    to specify the interrupt type, and in some cases the irq type depends
    on more than just the build configuration - it depends on runtime
    checks.

    Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
    a way for these flags to be passed via the IRQ resource itself.

    Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
    with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
    the low bits of PCI iomem resources correspond with the BAR flag bits.

    Also provide a way to configure smc91x to read the IRQ flags from the
    resource. Once all platforms have been converted over (signified
    by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
    be removed.

  • 650e9cfd1   blk_end_request: changing arm (take 4) ... Browse Code »

    This patch converts arm's OMAP mailbox driver to use
    blk_end_request interfaces.

    If the original code was converted literally, blk_end_request would
    be called with '-EIO' because end_that_request_last() were called
    with '0' (i.e. failure).
    But I think these '0's are bugs in the original code because it's
    unlikely that all requests are treated as failure.
    (The bugs should have no effect unless these requests have an end_io
    callback.)

    So I changed them to pass '0' (i.e. success) to blk_end_request.

    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  • f60493123   ARM: OMAP: abstract debug card setup (smc, leds) ... Browse Code »

    Additional cleanup for debug boards on H2/P2/H3/H4: move the init
    code that's not board-specific into a new file where it can be easily
    shared between all the different boards (avoiding code duplication,
    and making it easier to support more devices). Make H4 use that.

    This should be easy to drop in to the OMAP1 boards using these debug
    cards; the only difference seems to be that the p2 does an extra reset
    of the smc using the fpga (probably all boards could do that, if it's
    necessary) and doesn't use the gpio mux or request APIs.
