Subject: [PATCH v2 0/4] Pine64 PinePhone keyboard support
Date: Sat, 16 Apr 2022 21:16:28 -0500 [thread overview]
Message-ID: <20220417021633.56127-1-samuel@sholland.org> (raw)
This series adds support for the official keyboard case for the Pine64
PinePhone and PinePhone Pro. This accessory contains a keyboard MCU and
an IP5209 power bank IC. The keyboard MCU firmware[0] is free software.
It exposes the keyboard scan matrix over I2C, and also provides commands
for SMBus access to the IP5209. In order to keep the IP5209 driver
(CONFIG_IP5XXX_POWER) generic, this is modeled as a child I2C bus.

Changes in v2:
- Drop keymap DT properties
- Add vbat-supply property
- Fix missing key release events when FN state changes
- Add VBAT consumer to ensure enough power is available for the MCU
- Use a single fixed-size, fixed-contents keymap for both layers
Samuel Holland (4):
dt-bindings: input: Add the PinePhone keyboard binding
Input: pinephone-keyboard - Add PinePhone keyboard driver
