    Subject[PATCH 4.15 030/163] ARM: dts: nomadik: add interrupt-parent for clcd
    Date
    4.15-stable review patch.  If anyone has any objections, please let me know.

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

    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.
