Subject: [PATCH 2/2] platform/x86: touchscreen_dmi: Update info for the Chuwi Hi10 Plus (CWI527) tablet
Date: Sun, 5 Sep 2021 15:02:10 +0200 [thread overview]
Message-ID: <20210905130210.32810-2-hdegoede@redhat.com> (raw)
In-Reply-To: <20210905130210.32810-1-hdegoede@redhat.com>
Add info for getting the firmware directly from the UEFI for the Chuwi Hi10
Plus (CWI527), so that the user does not need to manually install the
firmware in /lib/firmware/silead.
This change will make the touchscreen on these devices work OOTB,
without requiring any manual setup.
Also tweak the min and width/height values a bit for more accurate position
reporting.
