From: Arnd Bergmann arnd@arndb.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@10120000 arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000
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.
