[PATCH 6.1 0304/1146] clk: renesas: r8a779f0: Fix HSCIF parent clocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

[ Upstream commit c258e3ab639112d8f5ae9df9a873750ae2623ce2 ]

As serial communication requires a clean clock signal, the High Speed
Serial Communication Interfaces with FIFO (HSCIF) are clocked by a clock
that is not affected by Spread Spectrum or Fractional Multiplication.

Hence change the parent clocks for the HSCIF modules from the S0D3_PER
clock to the SASYNCPERD1 clock (which has the same clock rate), cfr.
R-Car S4-8 Hardware User's Manual rev. 0.81.
