Subject: [PATCH v1 0/2] Input: psmouse: Introduce PixArt driver
Date: Wed, 15 May 2024 16:58:55 +0800 [thread overview]
Message-ID: <cover.1715224143.git.zhoubinbin@loongson.cn> (raw)
Hi all:
This patchset try to introduce the PixArt touchpad driver.
Unfortunately, due to the current design of the PixArt touchpad hardware
and FW, our single packet data width needs 11 bytes/15 bytes to receive
three-finger/four-finger data in absolute coordinate mode.
Obviously, it exceeds the design of the native driver, and we try to
extend the length of a single data packet to 16 bytes in patch(1/2).
I apologize that this radical change may not be the best way to go, and
I will try to rewrite this section if there are better suggestions.
Thanks.
