This is a note to let you know that I've just added the patch titled ARM: dts: renesas: r8a73a4: Fix external clocks and clock rate to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-dts-renesas-r8a73a4-fix-external-clocks-and-cloc.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b53384f6c1c9f86651745dd7cb122a29b34e874e Author: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Date: Mon Jan 15 12:03:03 2024 +0100 ARM: dts: renesas: r8a73a4: Fix external clocks and clock rate [ Upstream commit 090c4094574705b0afc7d37825cdc5d06f0e7e02 ] External clocks should be defined as zero-Hz clocks in the SoC .dtsi, and overridden in the board .dts when present. Correct the clock rate of extal1 from 25 to 26 MHz, to match the crystal oscillator present on the APE6-EVM board.
