The added sysfs attributes were helpful in debugging the problem. Patches that change the report rate on driver probing, mitigated crc errors on kernel bootup. The patch to get/set report rate by sysfs for an M12 device, has been tested. Changes in v4: - Add Rob Herring 'Acked-by' tag. Changes in v3: - Add hz unit suffix. - Add '|' to description. - Check the lower and upper limits of the report-rate-hz value - Convert the M06 report-rate-hz value Changes in v2: - Add Oliver Graute's 'Acked-by' tag to: * Input: edt-ft5x06 - show model name by sysfs * Input: edt-ft5x06 - show firmware version by sysfs - Fix yaml file. Tested with `make DT_CHECKER_FLAGS=-m dt_binding_check'.
