So, boot of these patches using this baseline fails when using MMC rootfs, but is ok when using initramfs. This particular compatible and the corresponding driver change are only in linux-next coming through couple of patches from the MMC subsystem. I am not sure why we would be including stuff that's dependent on some other patches being merged from a different sub-system? Strangely, this ought to be caught by dtbs_check, but it is not throwing any errors. IMHO, these should only be added if you have no other external dependencies especially when you are applying on a 5.11-rc baseline. The MMC pull-requests would not go through arm-soc either. regards Suman > + reg = <0x00 0xfa10000 0x00 0x260>, <0x00 0xfa18000 0x00 0x134>; > + interrupts = ; > + power-domains = <&k3_pds 57 TI_SCI_PD_EXCLUSIVE>;

So, boot of these patches using this baseline fails when using MMC rootfs, but is ok when using initramfs. This particular compatible and the corresponding driver change are only in linux-next coming through couple of patches from the MMC subsystem. I am not sure why we would be including stuff that's dependent on some other patches being merged from a different sub-system? Strangely, this ought to be caught by dtbs_check, but it is not throwing any errors. IMHO, these should only be added if you have no other external dependencies especially when you are applying on a 5.11-rc baseline. The MMC pull-requests would not go through arm-soc either. regards Suman > + reg = <0x00 0xfa10000 0x00 0x260>, <0x00 0xfa18000 0x00 0x134>; > + interrupts = ; > + power-domains = <&k3_pds 57 TI_SCI_PD_EXCLUSIVE>;
