Subject: [PATCH v3 4/4] [DO NOT MERGE] arm64: dts: allwinner: pinephone: Add keyboard
Date: Sun, 24 Apr 2022 11:04:57 -0500	[thread overview]

In-Reply-To: <20220424160458.60370-1-samuel@sholland.org>

The official PinePhone keyboard accessory connects to the phone's POGO
pins for I2C and interrupts. It has an Injoinic IP5209 power bank IC
connected to the keyboard's internal I2C bus.
