Subject: [PATCH v2 3/4] arm: dts: allwinner: t113s: add hstimer node
Date: Sun, 26 Apr 2026 12:15:28 +0200 [thread overview]
Message-ID: <20260426-h616-t113s-hstimer-v2-3-e65e9dc0c9da@mmpsystems.pl> (raw)
In-Reply-To: <20260426-h616-t113s-hstimer-v2-0-e65e9dc0c9da@mmpsystems.pl>
Describe high speed timer block on Allwinner T113-S3.
Tested on LCPI-PC-T113/F113:
- hstimer is registered as clocksource
- switching clocksource at runtime works
- after rating increase hstimer operates as a broadcast clockevent device
Signed-off-by: Michal Piekos <michal.piekos@mmpsystems.pl>
