[PATCH v8 1/4] cx25840: add pin to pad mapping and output format configuration
From: Maciej S. Szmigiero
Date: Wed Oct 10 2018 - 16:27:37 EST
This commit adds pin to pad mapping and output format configuration support
in CX2584x-series chips to cx25840 driver.
This functionality is then used to allow disabling ivtv-specific hacks
(called a "generic mode"), so cx25840 driver can be used for other devices
not needing them without risking compatibility problems.
