Subject: [PATCH v2 2/9] dt-bindings: nvmem: sfp: Add clock properties
Date: Fri, 22 Apr 2022 10:51:40 -0400 [thread overview]
Message-ID: <20220422145147.2210587-3-sean.anderson@seco.com> (raw)
In-Reply-To: <20220422145147.2210587-1-sean.anderson@seco.com>
To program fuses, it is necessary to set the fuse programming time. This
is determined based on the value of the platform clock. Add a clock
property.
