+/*
+ * LPC32XX CPU and system power management
+ *
+ * The LPC32XX has three CPU modes for controlling system power: run,
+ * direct-run, and halt modes. When switching between halt and run modes,
+ * the CPU transistions through direct-run mode. For Linux, direct-run
+ * mode is not used in normal operation. Halt mode is used when the
+ * system is fully suspended.
+ *
+ * Run mode:
+ * The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are
+ * derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from
+ * the HCLK_PLL rate. Linux runs in this mode.
+ *
+ * Direct-run mode:
+ * The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from
+ * SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK
+ * source or the frequency of the main oscillator. In this mode, the
+ * HCLK_PLL can be safely enabled, changed, or disabled.
+ *
+ * Halt mode:
+ * SYSCLK is gated off and the CPU and system clocks are halted.
+ * Peripherals based on the 32KHz oscillator clock (ie, RTC, touch,
+ * key scanner, etc.) still operate if enabled. In this state, an enabled
+ * system event (ie, GPIO state change, RTC match, key press, etc.) will
+ * wake the system up back into direct-run mode.
+ *
+ * DRAM refresh
+ * DRAM clocking and refresh are slightly different for systems with DDR
+ * DRAM or regular SDRAM devices. If SDRAM is used in the system, the
+ * SDRAM will still be accessible in direct-run mode. In DDR based systems,
+ * a transition to direct-run mode will stop all DDR accesses (no clocks).
+ * Because of this, the code to switch power modes and the code to enter
+ * and exit DRAM self-refresh modes must not be executed in DRAM. A small
+ * section of IRAM is used instead for this.
+ *
+ * Suspend is handled with the following logic:
+ *  Backup a small area of IRAM used for the suspend code
+ *  Copy suspend code to IRAM
+ *  Transfer control to code in IRAM
+ *  Places DRAMs in self-refresh mode
+ *  Enter direct-run mode
+ *  Save state of HCLK_PLL PLL
+ *  Disable HCLK_PLL PLL
+ *  Enter halt mode - CPU and buses will stop
+ *  System enters direct-run mode when an enabled event occurs
+ *  HCLK PLL state is restored
+ *  Run mode is entered
+ *  DRAMS are placed back into normal mode
+ *  Code execution returns from IRAM
+ *  IRAM code are used for suspend is restored
+ *  Suspend mode is exited
