Subject: [PATCH v2 0/2] Add RZ/V2M CSI slave support

Dear All,

the CSI IP found inside the Renesas RZ/V2M SoC supports
both SPI host and target.
This series extends the CSI dt-bindings and driver to
add SPI target support.

v1->v2: I have dropped properties renesas,csi-ss and
        renesas,csi-ss-high. I have added property
	renesas,csi-no-ss, and to configure SS as active
	high one now needs to use property spi-cs-high.
	I have also purged "master" and "slave" as naming
	schemes (besides for the title of the cover letter,
	to make it easier to follow this discussion), I
	am now using "host" and "target" and related APIs
	instead.

Cheers,
Fab
