Probably this:

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

arch/arm/boot/dts/tegra30-apalis.dtsi: stmpe811@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@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";

Yours,
