[PATCH 1/2] arm64: dts: qcom: sdm845-oneplus: Move touchscreen y-axis to the right place

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@ixit.cz>

This value belongs only to enchilada, fajita sets it's own (as the width
/ y-axis differs).

No functional change.

[PATCH 2/2] arm64: dts: qcom: sdm845-oneplus: Define touchscreen in the detail

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@ixit.cz>

Once probing, aftermarket touchscreens report touch over 0..65535
which is unusable. Be explicit in device-tree to avoid this issue.

This change should be irrelevant for original touchscreens, which
reports proper values.
