Subject: [PATCH] ARM: dts: r8a7790: Add TPU device node
Date: Mon, 20 Mar 2023 17:47:44 +0100	[thread overview]
Message-ID: <75da1e63135a3fc8a3aaafbff7139bd5d7509be3.1679330727.git.geert+renesas@glider.be> (raw)

Add support for the 4 PWM channels provided by the 16-bit Timer Pulse
Unit on R-Car H2, by adding a device node describing the TPU.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
Tested with PWM sysfs and a logic analyzer on the Lager development
board using DT overlays available from [1].

To be queued in renesas-devel-for-v6.4.
