Subject: [PATCH v3 1/5] platform/x86: int3472: Add new skl_int3472_fill_gpiod_lookup() helper
Date: Wed,  4 Oct 2023 18:23:13 +0200	[thread overview]
Message-ID: <20231004162317.163488-2-hdegoede@redhat.com> (raw)
In-Reply-To: <20231004162317.163488-1-hdegoede@redhat.com>

Add a new skl_int3472_fill_gpiod_lookup() helper.

This is a preparation patch for removing usage of the deprecated
gpiod_toggle_active_low() and acpi_get_and_request_gpiod() functions.
