Subject: [PATCH 2/3] pwm: meson: Add clock source configuration for Meson G12A
Date: Fri, 12 Apr 2019 11:23:36 +0200 [thread overview]
Message-ID: <20190412092337.6941-3-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190412092337.6941-1-narmstrong@baylibre.com>
For PWM controller in the Meson G12A SoC, the EE domain and AO domain
have different clock sources. This patch tries to describe them in the
DT compatible data.
