Subject: [PATCH v2 02/18] Revert "ARM: dts: imx6qdl-apalis: Avoid underscore in node name"

From: Max Krummenacher <max.krummenacher@...adex.com>

The STMPE MFD device binding requires the child node to have a fixed
name, i.e. with '_', not '-'. Otherwise the stmpe_adc, stmpe_touchscreen
drivers will not be probed.
