Date: Tue, 28 Sep 2021 01:56:24 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Hans de Goede <hdegoede@...hat.com>, Sasha Levin <sashal@...nel.org>, mgross@...ux.intel.com, linux-input@...r.kernel.org, platform-driver-x86@...r.kernel.org Subject: [PATCH AUTOSEL 5.10 03/23] platform/x86: touchscreen_dmi: Update info for the Chuwi Hi10 Plus (CWI527) tablet From: Hans de Goede <hdegoede@...hat.com> [ Upstream commit 196159d278ae3b49e7bbb7c76822e6008fd89b97 ] 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.
