2012-12-19ARM: S5P64X0: Add I2S clkdev supportPadmavathi Venna3-47/+75
I2S controller has an internal mux for RCLK source clk. The list of source clk names were passed through platform data in non-dt case. Register the existing RCLK source clocks with clkdev using generic connection id. This is required as part of adding DT support for I2S controller driver.

Pull preparatory gcc intrisics bswap patch from David Woodhouse: "This single patch is effectively a no-op for now. It enables architectures to opt in to using GCC's __builtin_bswapXX() intrinsics for byteswapping, and if we merge this now then the architecture maintainers can enable it for their arch during the next cycle without dependency issues. It's worth making it a par-arch opt-in, because although in *theory* the compiler should never do worse than hand-coded assembler (and of course it also ought to do a lot better on platforms like Atom and PowerPC which have load-and-swap or store-and-swap instructions), that isn't always the case. See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46453 for example." * tag 'byteswap-for-linus-20121219' of git://git.infradead.org/users/dwmw2/byteswap: byteorder: allow arch to opt to use GCC intrinsics for byteswapping

2012-12-18xtensa: add device trees supportMax Filippov7-25/+164
Device trees allow specification of hardware topology and device parameters at runtime instead of hard-coding them in platform setup code. This allows running single binary kernel on a range of compatible boards. New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat device tree is passed in it. Note that current interrupt mapping scheme uses single cell for interrupt identification. That means that IRQ numbers used in DTS must be CPU internal IRQ numbers, not external. It is possible to extend interrupt identification to two cells, and use second cell to tell external IRQ numbers form internal. That would allow to use single DTS on multiple boards with different mapping of external IRQ numbers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>

2012-12-18xtensa: add s32c1i sanity checkMax Filippov3-0/+135
Add a brief sanity test of S32C1I functionality. This instruction is needed by the kernel and userland as part of the base ABI (including GCC atomic builtins, certain threading packages, future atomic support in the C++ standard, etc). However, correct operation of this instruction requires some cooperation by hardware external to the processor (such as bus bridge, bus fabric, or memory controller). Minimally exercising this mechanism and reporting explicit status early in the boot process is helpful to chip vendors using the Linux kernel as a benchmark of correctness of hardware. As it turns out, S32C1I is not exercised by the kernel and by uClibc based userland as of early June 2008. This is expected to change soon as both incorporate more recent open source developments.
