[PATCH 6.1 0041/1146] arm64: dts: renesas: r8a779f0: Fix SCIF "brg_int" clock

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

 



From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

[ Upstream commit 64416ef0b0c4d73349035d1b3206eed3d2047ee0 ]

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

Hence change the clock input for the SCIF Baud Rate Generator internal
clock 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.

Fixes: c62331e8222f ("arm64: dts: renesas: Add Renesas R8A779F0 SoC support")
Fixes: 40753144256b ("arm64: dts: renesas: r8a779f0: Add SCIF nodes")
