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.
