If anyone has any objections, please let me know. ------------------ From: Fabio Estevam [ Upstream commit 7707e4555cf1d52689621e3206df8ad2debaa0dd ] The TSC2007 driver uses the ti,max-rt property to specify the maximum touch resistance, but the rk3566-bigtreetech-cb2 device tree uses the undocumented ti,rt-thr property instead. As a result, the configured value is ignored and the driver falls back to its default maximum resistance value of 4095. Replace ti,rt-thr with ti,max-rt to preserve the intended resistance threshold of 3000.
