Subject: [PATCH 1/2] hwmon: (pmbus/isl68137) Add support for Renesas RAA228942 and RAA228943
Date: Mon, 23 Mar 2026 11:20:56 +0800	[thread overview]
Message-ID: <20260323032057.953-2-dawei.liu.jy@renesas.com> (raw)
In-Reply-To: <20260323032057.953-1-dawei.liu.jy@renesas.com>

RAA228942 and RAA228943 are Renesas digital dual-output
16-phase (X+Y <= 16) PWM controllers with 2-rail non-TC
driver configuration. They have different hardware
interfaces and feature sets compared to existing
family members.
