I'm not insisting you should do the same, but it would be nice with some system to make it clear where new node refences should go. Or maybe I'm just not seeing the system you're already following. /Emil > > -- > 2.34.1 > > > _______________________________________________ > linux-riscv mailing list > linux-riscv@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-riscv

Add mmc0 properties for the eMMC device and add mmc1 properties for the microSD slot. Set the frequency for the sdhci clock. Signed-off-by: Drew Fustini <dfustini@baylibre.com> --- arch/riscv/boot/dts/thead/th1520-beaglev-ahead.dts | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+)
