2013-04-02ARM: shmobile: r8a7779: remove DIV4 clocks and use fixed ratio clockKuninori Morimoto1-87/+109
R-Car H1 has many clocks, and it is possible to read/use clock ratio of these clocks from FRQMRx as DIV4 clocks. But, these ratio are fixed value and these are decided by MD pin status. This means that we can use fixed ratio clock via MD pin status, instead of DIV4 clocks. This patch reads MD pin status, and sets PLLA clock (= root clock), and used fixed ratio clock for other clocks. It was tesed on marzen board.

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.

2013-04-02Merge tag 'renesas-intc-external-irq2-for-v3.10' into soc-baseSimon Horman14-128/+1115
Update for Renesas INTC External IRQ pin driver for v3.10 This adds support for shared interrupt lines to the Renesas INTC External IRQ pin driver which has already been queued up for v3.10 (tag renesas-intc-external-irq-for-v3.10). The patch "irqchip: intc-irqpin: Add support for shared interrupt lines" in renesas-intc-external-irq2-for-v3.10 is a dependency for "ARM: shmobile: r8a7740: Migrate from INTC to GIC". That dependency is the reason for this merge.
2013-03-28irqchip: intc-irqpin: Add support for shared interrupt linesBastian Hecht1-7/+83
On some hardware we don't have a 1-1 mapping from the external interrupts coming from INTC to the GIC SPI pins. We can however share lines to demux incoming IRQs on these SoCs. This patch enables the intc_irqpin driver to detect requests for shared interrupt lines and demuxes them properly by querying the INTC INTREQx0A registers. If you need multiple shared intc_irqpin device instances, be sure to mask out all interrupts on the INTC that share the one line before you start to register them. Else you run into IRQ floods that would be caused by interrupts for which no handler has been set up yet when the first intc_irqpin device is registered.

Provide alternate board code for the kzm9g to demonstrate how DT may be used given the current state of driver device tree support. This is intended to act as a reference for mach-shmobile developers. Some notes: * Brings up the GIC interrupt handler using device tree * Brings up the following device using device tree: - MMCIF (MMC) * Does not bring up the INTC interrupt controller at all, thus external devices may not be used. In particular, the SMSC ethernet device may not be used and thus NFS root may not be used. * Uses existing C code and not device tree to initialise the following, which are needed for a working board: - SCIF (Serial) - CMT (Clock) - PFC (GPIO) To use this alternate board code instead of the normal board code, CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config. And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.
