Series J7200: Add PCIe DT nodes to Enable PCIe | expand

Commit Message

Kishon Vijay Abraham I Nov. 2, 2020, 10:11 a.m. UTC
PCIe controller in J721E supports a maximum of 32 outbound regions.
commit 4e5833884f66 ("arm64: dts: ti: k3-j721e-main: Add PCIe device tree
nodes") incorrectly added maximum number of outbound regions to 16. Fix
it here.

Does this need to be part of this series? If NOT, please pull this  out
and repost so that it can be independently picked up since there is no
dependency on the bindings or any part of this series?

Can this be made detectable instead? Write to region registers and check 
the write sticks? I'm doing this for the DWC controller.

Or make the property optional with the default being the max (32).

okay, I'll make this an optional property and send a patch which removes
cdns,max-outbound-regions in k3-j721e-main.dtsi.
