+* Qualcomm WCNSS Pronto Peripheral Image Loader
+
+pil-pronto is a peripheral image loading (PIL) driver. It is used for loading
+Pronto firmware images for wireless connectivity subsystems into memory and
+preparing the subsystem's processor to execute code. It is also used for
+shutting down the processor when it's not needed.
+
+Required properties:
+- compatible: "pil-pronto"
+- reg: offset and length of the register set for the device.
+- reg-names: names of the bases for the above registers. "pmu_base", "clk_base",
+             and "halt_base" are expected.
+- interrupts: WCNSS to Apps watchdog bite interrupt
+- vdd_pronto_pll-supply: regulator to supply pronto pll.
+- qcom,firmware-name: Base name of the firmware image. Ex. "wcnss"
+- qcom,gpio-err-fatal: GPIO used by the wcnss to indicate error fatal to the Apps.
+- qcom,gpio-err-ready: GPIO used by the wcnss to indicate error ready to the Apps.
+- qcom,gpio-proxy-unvote: GPIO used by the wcnss to trigger proxy unvoting in
+  the Apps
+- qcom,gpio-force-stop: GPIO used by the Apps to force the wcnss to shutdown.

+Qualcomm MSS QDSP6v5 Peripheral Image Loader
+
+pil-qdsp6v5-mss is a peripheral image loader (PIL) driver. It is used for
+loading QDSP6v5 (Hexagon) firmware images for modem subsystems into memory and
+preparing the subsystem's processor to execute code. It's also responsible for
+shutting down the processor when it's not needed.
+
+Required properties:
+- compatible:	      Must be "qcom,pil-q6v5-mss"

+- vdd_cx-supply:      Reference to the regulator that supplies the vdd_cx domain.

+- vdd_mss-supply:     Reference to the regulator that supplies the processor.
