2013-03-25ARM: sirf: move irq driver to drivers/irqchipArnd Bergmann1-129/+0
This updates the irqchip drier for prima2 to the current practices by moving it into drivers/irqchip and integrating it into the irqchip_init infrastructure. We also now use a linear irq domain as a preparation for sparse IRQ suport. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Thomas Gleixner <tglx@linutronix.de>
2013-01-22ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for MarcoBarry Song1-2/+14
in Marco, we will use GIC. this patch prepares the handle_irq for prima2 to avoid the compiling errors since we want only one defconfig and zImage for both prima2 and marco that means we will need handle_irq for both. Signed-off-by: Baohua Song <Baohua.Song@csr.com>
2012-08-28ARM: SIRF: make sirf irqchip driver optional since new SoCs will have GICBarry Song1-1/+1
New MARCO and POLO SoC use GIC, so make irq.c optional and enable it only if we enable ARCH_PRIMA2 in Kconfig Signed-off-by: Barry Song <Baohua.Song@csr.com>

2012-02-16irq_domain: Remove irq_domain_add_simple()Grant Likely1-1/+1
irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

2011-09-21ARM: CSR: PM: save/restore irq status in suspend cycleBarry Song1-0/+40
SiRFprimaII will lose power in deepsleep mode except rtc, pmu and sdram self-refresh. So IRQ controller will lose status in suspend cyle. This patch saves irq mask/level registers while suspending and restore them while resuming. Signed-off-by: Barry Song <baohua.song@csr.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

2011-07-09ARM: CSR: Adding CSR SiRFprimaII board supportBinghua Duan1-0/+71
SiRFprimaII is the latest generation application processor from CSR’s Multifunction SoC product family. Designed around an ARM cortex A9 core, high-speed memory bus, advanced 3D accelerator and full-HD multi-format video decoder, SiRFprimaII is able to meet the needs of complicated applications for modern multifunction devices that require heavy concurrent applications and fluid user experience. Integrated with GPS baseband, analog and PMU, this new platform is designed to provide a cost effective solution for Automotive and Consumer markets. This patch adds the basic support for this SoC and EVB board based on device tree. It is following the ZYNQ of Xilinx in some degree.
