Subject: [PATCH v3 0/4] Pine64 PinePhone keyboard support
Date: Sun, 24 Apr 2022 11:04:53 -0500	[thread overview]
Message-ID: <20220424160458.60370-1-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 v3:
 - Replace unevaluatedProperties with additionalProperties
 - Rename i2c-bus to i2c

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

  dt-bindings: input: Add the PinePhone keyboard binding
  Input: pinephone-keyboard - Add PinePhone keyboard driver
  Input: pinephone-keyboard - Support the proxied I2C bus
