Merge tag 'sh-for-linus' of git://github.com/pmundt/linux-sh
Pull SuperH updates from Paul Mundt: - Migration off of old-style dynamic IRQ API. - irqdomain and generic irq chip propagation. - div4/6 clock consolidation, another step towards co-existing with the common struct clk infrastructure. - Extensive PFC rework - Decoupling GPIO from pin state. - Initial pinctrl support to facilitate incremental migration off of legacy pinmux. - gpiolib support made optional, and made pinctrl-backed. * tag 'sh-for-linus' of git://github.com/pmundt/linux-sh: (38 commits) sh: pfc: pin config get/set support. sh: pfc: Prefer DRV_NAME over KBUILD_MODNAME. sh: pfc: pinctrl legacy group support. sh: pfc: Ignore pinmux GPIOs with invalid enum IDs. sh: pfc: Export pinctrl binding init symbol. sh: pfc: Error out on pinctrl init resolution failure. sh: pfc: Make pr_fmt consistent across pfc drivers. sh: pfc: pinctrl legacy function support. sh: pfc: Rudimentary pinctrl-backed GPIO support. sh: pfc: Dumb GPIO stringification. sh: pfc: Shuffle PFC support core. sh: pfc: Verify pin type encoding size at build time. sh: pfc: Kill off unused pinmux bias flags. sh: pfc: Make gpio chip support optional where possible. sh: pfc: Split out gpio chip support. sh64: Fix up section mismatch warnings. sh64: Attempt to make reserved insn trap handler resemble C. sh: Consolidate die definitions for trap handlers. sh64: Kill off old exception debugging helpers. sh64: Use generic unaligned access control/counters. ...

21 * The IRQ bitmap provides a global map of bound IRQ vectors for a
22 * given platform. Allocation of IRQs are either static through the CPU
23 * vector map, or dynamic in the case of board mux vectors or MSI.
24 *
25 * As this is a central point for all IRQ controllers on the system,
26 * each of the available sources are mapped out here. This combined with
27 * sparseirq makes it quite trivial to keep the vector map tightly packed
28 * when dynamically creating IRQs, as well as tying in to otherwise
29 * unused irq_desc positions in the sparse array.
