Would you change this file name to "exynos_dp.c"?

Sorry, I don't think so  ;(

I think IP_name+Soc_name would be better in this re-use case.

So? Is there the naming rule such as "IP_name+SoC_name"?

Beside I see
there are lots of driver named with this format in kernel, such as dw_hdmi & dw_mmc

Please look at other dw cases.

For example, look at dw_pcie.

drivers/pci/host/

pcie-designware.c

pci-spear13xx.c

pci-exynos.c

In this case, pci-spear13xx.c and pci-exynos.c do not use "IP_name+SoC_name", even though these are dw IPs.

Also, naming consistency is more important.

Now, Exynos DRM files are using "exynos_drm_" prefix.

drivers/gpu/drm/exynos/

exynos_drm_buf.c

exynos_drm_core.c

....

However, "analogix_dp-exynos.c" looks very inconsistent.

If there is no strict naming rule, please use "exynos_dp.c"

or "exynos_drm_dp.c".
