2013-04-02ARM: shmobile: r8a7740: Migrate from INTC to GICBastian Hecht
With the added capabilty of the intc_irqpin driver to handle shared external IRQs, all prerequisites are fulfilled and we are ready to migrate completely to GIC. This includes the following steps: - Kconfig: select ARM_GIC and RENESAS_INTC_IRQPIN - intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need to mask out all shared IRQs as it is needed by the shared intc_irqpin driver. - setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update all IRQ numbers to point to the GIC SPI. - board-armadillo: Update all IRQ numbers to point to the GIC SPI. - pfc-r8a7740: Update all IRQ numbers of the GPIOs to point to the GIC SPI.

2012-06-20ARM: shmobile: r8a7740: add HDMI interrupt supportKuninori Morimoto
It is required from sh_mobile_hdmi driver. This patch is based on v1.0 manual Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-01-25ARM: shmobile: remove NR_IRQSRob Herring
Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile properly allocates irq_descs for each irqchip, so setting .nr_irqs for each machine is not needed. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2011-11-11ARM: mach-shmobile: r8a7740: add INTC supportKuninori Morimoto
R8A7740 GIC can not get external IRQx interrupt directly without GIC - INTC demux support. Current AG5 is using GIC - INTCS demux with special irq relocation. but GIC - INTCA demux is still not supported and it needs irq number re-mapping. OTOH, normal INTC support as before is very enough for R8A7740, because it is not SMP CPU. This patch adds INTCA/INTCS support instead of GIC.

2011-11-11ARM: mach-shmobile: R-Mobile A1 support.Kuninori Morimoto
This adds preliminary support for the R8A7740 (R-Mobile A1) CPU Timer, serial, gic, clock are supported at this point. This patch is based on v0.1 manual Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
