Subject: [PATCH 0/4] clk: ti: add am33xx spread spectrum clock support
Date: Sun, 14 Mar 2021 16:12:29 +0100	[thread overview]
Message-ID: <20210314151233.23243-1-dariobin@libero.it> (raw)


As reported by the TI spruh73x RM, MPU and LCD modules support spread
spectrum clocking (SSC) on their output clocks. SSC is used to spread
the spectral peaking of the clock to reduce any electromagnetic
interference (EMI) that may be caused due to the clock’s fundamental
or any of its harmonics.
The series allows you to enable and adjust the spread spectrum clocking
for all am33xx PLLs for which it is supported.
