Subject: [[PATCH v2] 2/9] dt-bindings: pwm: snps,pwm add pwm number
Date: Mon, 25 Jul 2022 22:21:33 +0100 [thread overview]
Message-ID: <20220725212140.741644-2-ben.dooks@sifive.com> (raw)
In-Reply-To: <20220725212140.741644-1-ben.dooks@sifive.com>
Add snps,pwm-number property to indicate if the block does not have
all 8 of the PWM blocks.
Not sure if this should be a general PWM property consider optional
for all PWM types, so have added a specific one here (there is only
one other controller with a property for PWM count at the moment)
