[PATCH 3/4] OMAPDSS: panel-sharp-ls037v7dw01: add device tree support

In many cases however we do have multiple compatible strings that
describe how the device is wired. See drivers/tty/serial/of_serial.c
for example. It has "ns16550" but then it also has additional
"nvidia,tegra20-uart", "nxp,lpc3220-uart" and "ibm,qpace-nwp-serial".

All those sound like SoC components. In that case it sounds fine to have
the device compatible contain the SoC name. We're talking here about
external, detachable devices.

Not use what you're after with the SPI example though, but sounds
like that's something different.

I think Sebastien's example is just like the issue here.

Hmm is there some existing example in the kernel like that?

No, Sebastien's example was just a hypothetical case. Here, using your
way of having SoC specific data in the .dts, we would have
"sharp,ls037v7dw01-omap-dss", and in Sebastien's example with a touch
sensor we'd have, say, "synaptics,xyz123-omap-spi".
