Subject: [PATCH] arm64: dts: renesas: r8a779h0: Add INTC-EX node
Date: Tue, 16 Apr 2024 17:40:01 +0200 [thread overview]
Message-ID: <66aba473186df9a137e7f95393209b23a5916fd1.1713281889.git.geert+renesas@glider.be> (raw)
Add the device node for the Interrupt Controller for External Devices
(INTC-EX) on the Renesas R-Car V4M (R8A779H0) SoC, which serves external
IRQ pins IRQ[0-5].
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
IRQ2 was tested on the Gray Hawk Single development board using
gpio-keys. With the default hardware setup, this causes an interrupt
storm, as expected (pin is shared with MD0).
To be queued in renesas-devel for v6.10.
