Subject: [PATCH 3/6] ARM: dts: omap2420-n810: Add Tahvo/Betty LEDPWM and Vcore bindings
Date: Fri, 24 Dec 2021 22:56:32 +0100 [thread overview]
Message-ID: <20211224215635.1585808-3-peter.vasil@gmail.com> (raw)
From: Peter Vasil <peter.vasil@gmail.com>
Nokia Tahvo/Betty ASIC provides PWM output for LED control and voltage
regulator for adjustable Vcore output.
These are both used on N8x0 devices for display control; LEDPWM for
backlight and Vcore for framebuffer IC power.
