[v2] spi: spi-fsl-lpspi: Generic fixes and support for S32G devices

[PATCH v2 5/9] dt-bindings: lpspi: Document support for S32G

Posted by James Clark 1 month ago

From: Larisa Grigore <larisa.grigore@nxp.com>

Add compatible strings 'nxp,s32g2-lpspi' and 'nxp,s32g3-lpspi' for S32G2
and S32G3. Require nxp,s32g3-lpspi to fallback to nxp,s32g2-lpspi since
they are currently compatible.
