Subject: [PATCH v7 2/3] arm64: dts: armada: add pwm offsets for ap/cp gpios
Date: Mon, 11 Jan 2021 13:46:28 +0200 [thread overview]
Message-ID: <75637257694de0d4a9e432e1d8270019a4e6328b.1610364681.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1610364681.git.baruch@tkos.co.il>
The 'marvell,pwm-offset' property of both GPIO blocks (per CP component)
point to the same counter registers offset. The driver will decide how
to use counters A/B.
This is different from the convention of pwm on earlier Armada series
(370/38x). On those systems the assignment of A/B counters to GPIO
blocks is coded in both DT and the driver. The actual behaviour of the
current driver on Armada 8K/7K is the same as earlier systems.
Add also clock properties for base pwm frequency reference.
