If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e03b9269f8890c9de6468966048cdae7872c7c4c Author: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx> Date: Thu Nov 3 15:34:39 2022 +0100 arm64: dts: renesas: r8a779f0: Fix HSCIF "brg_int" clock [ Upstream commit a5101ef18b4d0751588f61d939694bad183cc240 ] 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 clock input for the HSCIF Baud Rate Generator internal clock from the S0D3_PER clock to the SASYNCPERD1 clock (which has the same clock rate), cfr.
