ns9xxx: prepare for adding support for Digi ns921x processors The hardware team changed some things that were taken as being common to all ns9xxx processors up to now. This patch addresses: - irqs: s/IRQ_/IRQ_NS9360_/ - system module registers: some registers are still general, their definition lives now in include/asm-arm/arch-ns9xxx/regs-sys-common.h. The ns9360 specific ones are in .../regs-sys-ns9360.h As a result ns9360_systemclock cannot be static inline any more as its definition needs regs-sys-ns9360.h. This becomes a real problem when adding support for ns9215 as this will need regs-sys-ns9215.h and including both files will not work. For the same reason ns9360_reset() is now non-inline and gpio functions live in their own file. - register mapping: s/ns9xxx_map_io/ns9360_map_io/ - timer registers: move time.c to time-ns9360.c; s/ns9xxx_timer/ns9360_timer/ Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>

[ARM] 4234/1: Introduce get_irqnr_preamble and arch_ret_to_user for ns9xxx. This is a follow up for f80dff9da07d81da16e3b842118d47b9febf9c01 which didn't include adaption for the new ns9xxx machine support.

ns9xxx: Use get_irqnr_preamble to initialize base register This patch optimizes the irq handling a bit. Now the base register is only computed once if more than one irq is pending. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
