Hi,

I have the SSD1306 oled device connected via spi, will the same
driver work ? as the current one is based on i2c what all mods would
be required to have it working with SPI ?

It won't work out of the box, but it should be fairly easy to support.

You need to had support for SPI probing, and then provide some generic
accessors the rest of the code can use to wrap around the i2c and spi
calls.

I'm not sure regmap can be used for this, but this would be something
worth looking into to do that.

Thanks for the inputs :)

Does the driver work as a standard fbdev driver, is there any library on top
of it to ease the user space ?

It exposes a monochrome fbdev, so the usual framebuffer tools and
libraries are supposed to work quite well, provided they've been
written to handle monochrome displays.
