Being the name of a machine driver, it aims to describe the connection between the HDMI IP of the processor and the companion chip it uses to connect to the outside world. This name tries to follow the same naming convention as in the OMAP-ABE-TWL6040 machine driver.
TPD12S015 is an HDMI companion chip for DC-DC step-up, I2C level shifter and low-capacitance ESD protection. This chip is used on all OMAP4 Pandaboards an SDPs as well as in OMAP5 EVMs.
Is the TPD12S015 passive or actively controlled by the CPU in this case ?
If it's passive then it's not really worth changing the driver name since other OMAP4/5 devices may use other HDMI companion chips (an we can reuse this driver without changes).
