Subject: [PATCH linux v2 0/3] spi: aspeed: Add a "ranges" property

Hello,

Currently, the Linux Aspeed SMC driver computes the decoding ranges of
each CS (AHB memory window on which the flash contents are mapped)
from the size of the detected flash device. It seems that some chips
have issues with the computed ranges and for these, it would be nice
to be able to define custom decoding ranges in the DT.

Here is a little series doing that. 

Thanks,

C. 

Changes in v2 :

 - Tested by Naresh Solanki
 - sent preliminary fix independently
   https://patchwork.kernel.org/project/linux-arm-kernel/patch/20221016155722.3520802-1-clg@kaod.org/
 - changed the sysfs file exposing the register values to debugfs.
 - refresh on 6.1-rc1
