Subject: [PATCH 2/3] pwm: meson: Use separate chip data struct for g12a-ee-pwm
Date: Mon, 7 Oct 2024 22:32:02 +0300	[thread overview]
Message-ID: <20241007193203.1753326-3-gnstark@salutedevices.com> (raw)
In-Reply-To: <20241007193203.1753326-1-gnstark@salutedevices.com>

PWM module of g12a SoC family has different set of features than meson8
so use separate chip data struct for it.
