+ * LPC32xx clock management driver overview
+ *
+ * The LPC32XX contains a number of high level system clocks that can be
+ * generated from different sources. These system clocks are used to
+ * generate the CPU and bus rates and the individual peripheral clocks in
+ * the system. When Linux is started by the boot loader, the system
+ * clocks are already running. Stopping a system clock during normal
+ * Linux operation should never be attempted, as peripherals that require
+ * those clocks will quit working (ie, DRAM).
+ *
+ * The LPC32xx high level clock tree looks as follows. Clocks marked with
+ * an asterisk are always on and cannot be disabled. Clocks marked with
+ * an ampersand can only be disabled in CPU suspend mode. Clocks marked
+ * with a caret are always on if it is the selected clock for the SYSCLK
+ * source. The clock that isn't used for SYSCLK can be enabled and
+ * disabled normally.
+ *                               32KHz oscillator*
+ *                               /      |      \
+ *                             RTC*   PLL397^ TOUCH
+ *                                     /
+ *               Main oscillator^     /
+ *                   |        \      /
+ *                   |         SYSCLK&
+ *                   |            \
+ *                   |             \
+ *                USB_PLL       HCLK_PLL&
+ *                   |           |    |
+ *            USB host/device  PCLK&  |
+ *                               |    |
+ *                             Peripherals
+ *
+ * The CPU and chip bus rates are derived from the HCLK PLL, which can
+ * generate various clock rates up to 266MHz and beyond. The internal bus
+ * rates (PCLK and HCLK) are generated from dividers based on the HCLK
+ * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate,
+ * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high
+ * level clocks are based on either HCLK or PCLK, but have their own
+ * dividers as part of the IP itself. Because of this, the system clock
+ * rates should not be changed.
+ *
+ * The HCLK PLL is clocked from SYSCLK, which can be derived from the
+ * main oscillator or PLL397. PLL397 generates a rate that is 397 times
+ * the 32KHz oscillator rate. The main oscillator runs at the selected
+ * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate
+ * is normally 13MHz, but depends on the selection of external crystals
+ * or oscillators. If USB operation is required, the main oscillator must
+ * be used in the system.
+ *
+ * Switching SYSCLK between sources during normal Linux operation is not
+ * supported. SYSCLK is preset in the bootloader. Because of the
+ * complexities of clock management during clock frequency changes,
+ * there are some limitations to the clock driver explained below:
+ * - The PLL397 and main oscillator can be enabled and disabled by the
+ *   clk_enable() and clk_disable() functions unless SYSCLK is based
+ *   on that clock. This allows the other oscillator that isn't driving
+ *   the HCLK PLL to be used as another system clock that can be routed
+ *   to an external pin.
+ * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with
+ *   this driver.
+ * - HCLK and PCLK rates cannot be changed as part of this driver.
+ * - Most peripherals have their own dividers are part of the peripheral
+ *   block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates
+ *   will also impact the individual peripheral rates.

+/*
+ * LPC32XX CPU and system power management
+ *
+ * The LCP32XX 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 transistion 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
