Subject: [PATCH RFC v3 2/6] arm: dts: marvell: armada-388-clearfog-base: add rfkill for m.2
Date: Sat, 20 Jul 2024 16:19:19 +0200	[thread overview]
Message-ID: <20240720-a38x-utmi-phy-v3-2-4c16f9abdbdc@solid-run.com> (raw)
In-Reply-To: <20240720-a38x-utmi-phy-v3-0-4c16f9abdbdc@solid-run.com>

Armada 388 Clearfog Base has a USB-3.0 / SATA capable m.2 connector,
with various pins controlled by the host:

- FULL_CARD_POWER_OFF#: When low, M.2 LTE modules are switched off.
  Many modules include pull-down, thus it must be driven high actively.
- RESET#: Puts modules into reset when low. Modules are expected to
  include pull-up.
- GNSS_DISABLE#
- W_DISABLE#

Add rfkill devices for gnss and wwan.
