Subject: [PATCH 4.14 029/167] ARM: dts: nomadik: add interrupt-parent for clcd

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit e8bfa0422469cdfc86be3f525f621b1d44d2481b upstream.

The clcd device is lacking an interrupt-parent property, which makes
the interrupt unusable and shows up as a warning with the latest
dtc version:

arch/arm/boot/dts/ste-nomadik-s8815.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@...20000
arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@...20000

I looked up the old board files and found that this interrupt has
the same irqchip as all the other on-chip device, it just needs one
extra line.
