ARM: mach-shmobile: sh73a0: Allow initialisation of GIC by DT This allows the GIC interrupt controller of the sh73a0 SoC to be initialised using a flattened device tree blob. It does not allow the INTC interrupt controller which is also present on the sh73a0 SoC to be enabled via device tree. Nor does it handle sharing of interrupts between the GIC and INTC interrupt controllers. This limits the usefulness of this code to applications which only wish to access devices which use interrupts that can be handled by the GIC interrupt controller. Other applications should, for now, continue using non-device tree initialisation of the sh72a0 interrupt controllers. Includes update to use irqchip_init() by Thierry Reding Cc: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

ARM: mach-shmobile: sh73a0: Minimal setup using DT Allow a minimal setup of the sh73a0 SoC using a flattened device tree. In particular, Configure the i2c controllers using a flattened device tree. SCI serial controller and CMT clock source, whose drivers do not yet support configuration using a flattened device tree, are still configured using C code in order to allow booting of a board with this SoC. *** Please note that the clock initialisation scheme used in this patch does not currently work with SMP as there is a yet to be resolved lock-up in workqueue initialisation. CONFIG_SMP must be disabled when using this code. *** Includes update from Thierry Reding to no longer use gic_handle_irq() Cc: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au> fix
