Subject: [PATCH 12/12] platform/x86: x86-android-tablets: Add TM800A550L data
Date: Thu, 30 Dec 2021 00:14:31 +0100 [thread overview]
Message-ID: <20211229231431.437982-13-hdegoede@redhat.com> (raw)
In-Reply-To: <20211229231431.437982-1-hdegoede@redhat.com>
The whitelabel (sold as various brands) TM800A550L tablets's DSDT contains
a whole bunch of bogus ACPI I2C devices and the ACPI node describing
the touchscreen is bad (the IRQ is missing). Enumeration of these is
skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the (now) missing I2C devices by
adding the necessary device info to the x86-android-tablets module,
including instantiating an actually working i2c-client for
the touchscreen.
