Subject: [PATCH v11 10/10] platform/x86: touchscreen_dmi: Add info for the Chuwi Vi8 Plus tablet
Date: Sat, 11 Jan 2020 15:57:03 +0100 [thread overview]
Message-ID: <20200111145703.533809-11-hdegoede@redhat.com> (raw)
In-Reply-To: <20200111145703.533809-1-hdegoede@redhat.com>
Add touchscreen info for the Chuwi Vi8 Plus tablet. This tablet uses a
Chipone ICN8505 touchscreen controller, with the firmware used by the
touchscreen embedded in the EFI firmware.
Acked-by: Andy Shevchenko <andy.shevchenko@gmail.com>

Changes in v7:
- Remove PROPERTY_ENTRY_BOOL("efi-embedded-firmware") properties entry,
as this is no longer necessary
Changes in v6:
- Switch from crc sums to SHA256 hashes for the firmware hash
