Subject: [RFC PATCH v2 05/10] ARM: at91: make use of the new AIC driver for dt enabled boards
Add a new Kconfig option for the new AIC driver
(drivers/irqchip/irq-atmel-aic.c) and remove selection of OLD_IRQ_AT91
when selecting dt boards.
Remove specific irq init code in all dt board files: this init procedure
is automatically handled in of_irq_init which is called by the arm irq core
code and is in charge of calling the appropriate aic init functions.
Signed-off-by: Boris BREZILLON <b.brezillon.dev@...il.com>
