[Abhyuday] During rebase of patches on your tree couple of lines code was get mixed unintendedly in xlnx-zynqmp.h header file due to use of "git am -3".
I corrected the below code which was wrong in previous patch v5.
+static inline int zynqmp_pm_register_notifier(const u32 node, const u32 event,
+					      const u32 wake, const u32 enable) {
+	return -ENODEV;
+}

In v5 it was like below, which is wrong
static inline int zynqmp_pm_load_pdi(const u32 src, const u64 address)
static inline int zynqmp_pm_register_notifier(const u32 node, const u32 event,
					      const u32 wake, const u32 enable) {
	return -ENODEV;
}
So, the body was missing here for zynqmp_pm_load_pdi in v5.

Thanks,
Abhyuday
