    Subject[PATCH v4 0/4] Pine64 PinePhone keyboard support
    Date
    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 v4:
    - Rebase to resolve MAINTAINERS merge conflict
    - Add missing newlines in error messages

    Changes in v3:
    - Replace unevaluatedProperties with additionalProperties
    - Rename i2c-bus to i2c
    - 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
