ADV7511 Linux drivers, DRM vs. V4L2

In the process of seeking out a Linux driver for the ADV7511 HDMI Transmitter for our custom hardware, I see that the ADV7511 support page directs us to a DRM driver.

https://github.com/analogdevicesinc/linux/blob/xcomm_zynq/drivers/gpu/drm/i2c/adv7511_core.c

 

In a different portion of the Linux drivers directory tree of the same code base, there is also a V4L2 driver

https://github.com/analogdevicesinc/linux/blob/xcomm_zynq/drivers/media/i2c/adv7511.c

 

Could someone please explain the history/evolution of the two drivers?  Both drivers appear to be targeted for the same hardware platform.  Both drivers appear to be actively maintained.  Are one of these two drivers considered to be more stable or reliable than the other?
