Himax HX852x(ES) is a touch panel controller with optional support for capacitive touch keys. Unfortunately, the model naming is quite unclear and confusing. There seems to be a distinction between models (e.g. HX8526) and the "series" suffix (e.g. -A, -B, -C, -D, -E, -ES). But this doesn't seem to be applied very consistently because e.g. HX8527-E(44) actually seems to belong to the -ES series. The compatible consists of the actual part number followed by the "series" as fallback compatible. Typically only the latter will be interesting for drivers as there is no relevant difference on the driver side.
