* rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712.Paul Mundt2007-09-20
| | | | | | | | | | | | | | All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.

* sh: intc - add support for SH7785Magnus Damm2007-09-20
| | | | | | | | | | | | This patch converts the cpu specific interrupt setup code for sh7785 from intc2 to intc. New vectors are also added to match the information provided by the datasheet. No IRQ/IRL pin vectors are enabled by default. Use plat_irq_setup_pins() to select between IRL and IRQ mode.

* sh: Fix Dreamcast DMA issues.Adrian McMenamin2007-07-24
| | | | | | | | | | | | | The current SH DMA API is somewhat broken, not correctly matching virtual channel to the correct SH DMAC.

* sh: Add kmap_coherent()/kunmap_coherent() interface for SH-4.Paul Mundt2007-07-24
| | | | | | | | | | | | | This wires up kmap_coherent() and kunmap_coherent() on SH-4, and moves away from the p3map_mutex and reserved P3 space, opting to use fixmaps for colouring instead. The copy_user_page()/clear_user_page() implementations are moved to this, which fixes the nasty blowups with spinlock debugging as a result of having some of these calls nested under the page table lock.

Many new vectors are added and multiple processor variants including 7091, 7750, 7750s, 7750r, 7751 and 7751r should all have the correct vectors hooked up.

* sh: intc - shared IPR and INTC2 controllerMagnus Damm2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | This is the second version of the shared interrupt controller patch for the sh architecture, fixing up handling of intc_reg_fns[]. The three main advantages with this controller over the existing ones are: - Both priority (ipr) and bitmap (intc2) registers are supported - External pin sense configuration is supported, ie edge vs level triggered - CPU/Board specific code maps 1:1 with datasheet for easy verification This controller can easily coexist with the current IPR and INTC2 controllers, but the idea is that CPUs/Boards should be moved over to this controller over time so we have a single code base to maintain.

| | | | | | | | | | | | | | | | | | | | | | | | | | SH is able to support a complete futex implementation on UP by way of gUSA. However, IRQ toggling must be done for the old CPUs that don't have movli.l/movco.l (LL/SC) instructions. Provide a default implementation that does this, so it's possible to optimize for newer CPUs.

| * sh: rework ipr codeMagnus Damm2007-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the ipr code by grouping the offset array together with the ipr_data structure in a new data structure called ipr_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. This strategy has much in common with the recently merged intc2 code. One logic change has been made - the original ipr code enabled the interrupts by default but with this patch they are all disabled by default.
