Subject: [PATCH 0/2] serial: msm: Allow scaling power domains and interconnect
Date: Tue, 28 Nov 2023 10:43:31 +0100 [thread overview]
Message-ID: <20231128-serial-msm-dvfs-v1-0-4f290d20a4be@kernkonzept.com> (raw)
Make it possible to scale performance states of the power domain and
interconnect of the UART DM controller in relation to the selected UART
baud rate. This is done by setting up an OPP table in the device tree
that describes the necessary power domain states in relation to the UART
clock rate.
