I'm not quite sure what this issue is asking for. The mentioned targets only contain one GP-SPI

While it's technically possible to use SPI1 we don't support that and I'm not sure if we ever will or should (I'd personally say we shouldn't)

The idea is to use I2S on these devices (or all of them).

Ok nice - C2 doesn't include I2S IIRC but at least this clarifies the issue a bit

[bugadani]

To be honest this is a bit of a non-issue anyway. With the Xtensas we have a test for both PDMA and GDMA devices and the original issue wasn't exactly device-specific.

Hint: the PR which introduced the test is #2065
