Pinmux for ECSPI SS[1:3] on iMX8M-Mini

[pa1]

I have reviewed the iMX8M-Mini reference manual and in section 10.1.1.1 it states that the ECSPI block has four slave select signals on each block. This is also reflected in the config registers.

However, I am not able to find a pinmux that will enable anything else than SS0 from any of the blocks.

Anybody know how to get the SS[1:3] signals out of the device.?

Found that basically the same question is asked here for iMX8M:

If the case is that SS1-3 are not routed externally I agree with the comments in the post that these references should be removed, since it is not a valid configuration to use anything else than SS0 from the IP block.

Hi PA

you are right, it is the same explanation for i.MX8M Mini.
