DaVinci SoC updates for v5.1 (part 3)
-------------------------------------
This pull request gets rid of mach-davinci private interrupt controller
implmentations (aintc and cp_initc) and moves them to drivers/irqchip.

mach/irqs.h usage outside of mach-davinci has been rid of.

The driver changes (input and irqchip) have been acked by respective
maintainers.

* tag 'davinci-for-v5.1/soc-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: (57 commits)
