Subject: [PATCH v12 10/10] platform/x86: touchscreen_dmi: Add info for the Chuwi Vi8 Plus tablet
Date: Wed, 15 Jan 2020 17:35:54 +0100
Message-ID: <20200115163554.101315-11-hdegoede@redhat.com> (raw)
In-Reply-To: <20200115163554.101315-1-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>
Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
Signed-off-by: Hans de Goede <hdegoede@redhat.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
