Subject: ARM: 7023/1: L2x0: Add interrupts property to OF binding
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8d4e652d1b2539196efaef051956fa29e22e9c10;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: 7023/1: L2x0: Add interrupts property to OF binding

Following the discussion here:
http://lists.ozlabs.org/pipermail/devicetree-discuss/2011-August/007301.html

The L2x0 L2 Cache Controllers support a combined interrupt line
which can be used for several events (e.g. read/write/parity errors on
tag/data RAM, event counter increment/overflow). Unfortunately the
OF binding added in c519ecf2 ("ARM: 7009/1: l2x0: Add OF based
initialization") does not represent the interrupt.

This patch adds an "interrupts" property to the L2x0 OF binding,
representing the combined interrupt line.
