[Impact]
[Fix]
[Test]
[Where problem could occur] |
[Impact]
On some platforms, the EC doesn't support the register reading sequence
for sentelic[1], and then make the EC can't respond commands for a while
when probing. It leads to the keyboard is non-responsive for around 10
seconds while waking up from s2idle.

[ 48.402624] i8042: [10556] f6 -> i8042 (parameter)
[Fix]
A DMI quirk to mark this platform doesn't have aux device could avoid those commands to be sent. And the system could still using i2c
interface to communicate with the touchpad.
[Test]
Verified on Dell Precision 5550
[Where problem could occur]
The quirk only affects the listed platform, there is no regression could occur. |
