There is no single need to store automated output of get_maintainers.pl in the git log. It can be easily re-created at any given time, thus its presence in the git history is redundant and obfuscates the log. If you need it for your own patch management purposes, keep it under the --- separator. > --- > Changes since v2: > - added led indictors > - sdhci1 use MMC1_SDCD.GPIO1_48 for card detect > - cleaned up order of status = "okay" > - wkup_i2c0 moved to 100000 > - eeprom added atmel,24c32 > - rtc added dallas,ds1340 > - sdhci1 use ti,fails-without-test-cd > Changes since v1: > - fixed incorrect vdd-3v3-sd-pins-default name > - updated hdmi VDD_1V2 regulator for production pcb > - switched device tree name from k3-j722s-beagley-ai to k3-am67a-beagley-ai > - removed cpsw_port2 node > - enable UHS support for MMCSD > --- > arch/arm64/boot/dts/ti/Makefile | 1 + > .../arm64/boot/dts/ti/k3-am67a-beagley-ai.dts | 406 ++++++++++++++++++ > 2 files changed, 407 insertions(+) > create mode 100644 arch/arm64/boot/dts/ti/k3-am67a-beagley-ai.dts > > diff --git a/arch/arm64/boot/dts/ti/Makefile b/arch/arm64/boot/dts/ti/Makefile > index e20b27ddf901..c89c9b8bab38 100644 > --- a/arch/arm64/boot/dts/ti/Makefile > +++ b/arch/arm64/boot/dts/ti/Makefile > @@ -110,6 +110,7 @@ dtb-$(CONFIG_ARCH_K3) += k3-j721s2-evm.dtb > dtb-$(CONFIG_ARCH_K3) += k3-j721s2-evm-pcie1-ep.dtbo > > # Boards with J722s SoC > +dtb-$(CONFIG_ARCH_K3) += k3-am67a-beagley-ai.dtb So am67 is J772s?
