+What: /sys/power/pm_wakeup_irq
+Date: April 2015
+Contact: Alexandra Yates <alexandra.yates@linux.intel.org>
+Description:
+ The /sys/power/pm_wakeup_irq file reports to user space the IRQ
+ number of the first wakeup interrupt (that is, the first
+ interrupt from an IRQ line armed for system wakeup) seen by the
+ kernel during the most recent system suspend/resume cycle.
+
+ This output is useful for system wakeup diagnostics of spurious
+ wakeup interrupts.
--- /dev/null
+This file contains documentation for running mainline
+kernel on omaps.
+
+KERNEL NEW DEPENDENCIES
+v4.3+ Update is needed for custom .config files to make sure
+ CONFIG_REGULATOR_PBIAS is enabled for MMC1 to work
+ properly.

+ * information from a per CPU table called CPC. This table is described in
+ * the ACPI v5.0+ specification. The table consists of a list of
+ * registers which may be memory mapped or hardware registers and also may
+ * include some static integer values.
+ *
+ * CPU performance is on an abstract continuous scale as against a discretized
+ * P-state scale which is tied to CPU frequency only. In brief, the basic
+ * operation involves:
+ *
+ * - OS makes a CPU performance request. (Can provide min and max bounds)
+ *
+ * - Platform (such as BMC) is free to optimize request within requested bounds
+ * depending on power/thermal budgets etc.
+ *
+ * - Platform conveys its decision back to OS
+ *
+ * The communication between OS and platform occurs through another medium
+ * called (PCC) Platform Communication Channel. This is a generic mailbox like
+ * mechanism which includes doorbell semantics to indicate register updates.
+ * See drivers/mailbox/pcc.c for details on PCC.
+ *
+ * Finer details about the PCC and CPPC spec are available in the ACPI v5.1 and
+ * above specifications.
