Probably this:

$ git grep stmpe arch/arm/boot/dts/

arch/arm/boot/dts/tegra30-apalis.dtsi:          stmpe811 at 41 {
arch/arm/boot/dts/tegra30-apalis.dtsi:                  compatible =
"st,stmpe811";
arch/arm/boot/dts/tegra30-apalis.dtsi:                  stmpe_touchscreen {
arch/arm/boot/dts/tegra30-apalis.dtsi:
compatible = "st,stmpe-ts";
arch/arm/boot/dts/tegra30-colibri.dtsi:         stmpe811 at 41 {
arch/arm/boot/dts/tegra30-colibri.dtsi:                 compatible =
"st,stmpe811";
arch/arm/boot/dts/tegra30-colibri.dtsi:                 stmpe_touchscreen {
arch/arm/boot/dts/tegra30-colibri.dtsi:
compatible = "st,stmpe-ts";
