Subject: [PATCH v1 8/9] ARM: tegra: tf600t: Drop backlight regulator
Date: Mon,  6 Apr 2026 11:34:03 +0300	[thread overview]
Message-ID: <20260406083404.31359-9-clamor95@gmail.com> (raw)
In-Reply-To: <20260406083404.31359-1-clamor95@gmail.com>

Drop dedicated backlight regulator since the GPIO used in it is actually
SFIO controlling backlight and setting it as GPIO causes backlight to
freeze at maximum level.

Tested-by: Andreas Westman Dorcsak <hedmoo@yahoo.com>
