Subject: [PATCH v1 5/5] drm/bridge: tc358768: Correct BTACNTRL1 programming
Date:   Sun,  3 Oct 2021 02:34:47 +0300

TXTAGOCNT and RXTASURECNT bitfields of BTACNTRL1 register are swapped in
the code, correct them. Driver doesn't implement low power mode for now,
so this change doesn't make a practical difference yet.
