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

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".
