20 | * LPC32xx clock management driver overview | ||
21 | * | ||
22 | * The LPC32XX contains a number of high level system clocks that can be | ||
23 | * generated from different sources. These system clocks are used to | ||
24 | * generate the CPU and bus rates and the individual peripheral clocks in | ||
25 | * the system. When Linux is started by the boot loader, the system | ||
26 | * clocks are already running. Stopping a system clock during normal | ||
27 | * Linux operation should never be attempted, as peripherals that require | ||
28 | * those clocks will quit working (ie, DRAM). | ||
29 | * | ||
30 | * The LPC32xx high level clock tree looks as follows. Clocks marked with | ||
31 | * an asterisk are always on and cannot be disabled. Clocks marked with | ||
32 | * an ampersand can only be disabled in CPU suspend mode. Clocks marked | ||
33 | * with a caret are always on if it is the selected clock for the SYSCLK | ||
34 | * source. The clock that isn't used for SYSCLK can be enabled and | ||
35 | * disabled normally. | ||

48 | * | | | ||
49 | * Peripherals | ||
50 | * | ||
51 | * The CPU and chip bus rates are derived from the HCLK PLL, which can | ||
52 | * generate various clock rates up to 266MHz and beyond. The internal bus | ||
53 | * rates (PCLK and HCLK) are generated from dividers based on the HCLK | ||
54 | * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate, | ||
55 | * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high | ||
56 | * level clocks are based on either HCLK or PCLK, but have their own | ||
57 | * dividers as part of the IP itself. Because of this, the system clock | ||
58 | * rates should not be changed. | ||
59 | * | ||
60 | * The HCLK PLL is clocked from SYSCLK, which can be derived from the | ||
61 | * main oscillator or PLL397. PLL397 generates a rate that is 397 times | ||
62 | * the 32KHz oscillator rate. The main oscillator runs at the selected | ||
63 | * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate | ||
64 | * is normally 13MHz, but depends on the selection of external crystals | ||
65 | * or oscillators. If USB operation is required, the main oscillator must | ||
66 | * be used in the system. | ||
67 | * | ||
68 | * Switching SYSCLK between sources during normal Linux operation is not | ||
69 | * supported. SYSCLK is preset in the bootloader. Because of the | ||
70 | * complexities of clock management during clock frequency changes, | ||
71 | * there are some limitations to the clock driver explained below: | ||
72 | * - The PLL397 and main oscillator can be enabled and disabled by the | ||
73 | * clk_enable() and clk_disable() functions unless SYSCLK is based | ||
74 | * on that clock. This allows the other oscillator that isn't driving | ||
75 | * the HCLK PLL to be used as another system clock that can be routed | ||
76 | * to an external pin. | ||
77 | * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with | ||
78 | * this driver. | ||
79 | * - HCLK and PCLK rates cannot be changed as part of this driver. | ||
80 | * - Most peripherals have their own dividers are part of the peripheral | ||
81 | * block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates | ||
82 | * will also impact the individual peripheral rates. | ||

14 | * LPC32XX CPU and system power management | ||
15 | * | ||
16 | * The LCP32XX has three CPU modes for controlling system power: run, | ||
17 | * direct-run, and halt modes. When switching between halt and run modes, | ||
18 | * the CPU transistions through direct-run mode. For Linux, direct-run | ||
19 | * mode is not used in normal operation. Halt mode is used when the | ||
20 | * system is fully suspended. | ||
21 | * | ||
22 | * Run mode: | ||
23 | * The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are | ||
24 | * derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from | ||
25 | * the HCLK_PLL rate. Linux runs in this mode. | ||
26 | * | ||
27 | * Direct-run mode: | ||
28 | * The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from | ||
29 | * SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK | ||
30 | * source or the frequency of the main oscillator. In this mode, the | ||
31 | * HCLK_PLL can be safely enabled, changed, or disabled. | ||
32 | * | ||
33 | * Halt mode: | ||
34 | * SYSCLK is gated off and the CPU and system clocks are halted. | ||
35 | * Peripherals based on the 32KHz oscillator clock (ie, RTC, touch, | ||
36 | * key scanner, etc.) still operate if enabled. In this state, an enabled | ||
37 | * system event (ie, GPIO state change, RTC match, key press, etc.) will | ||
38 | * wake the system up back into direct-run mode. | ||
39 | * | ||
40 | * DRAM refresh | ||
41 | * DRAM clocking and refresh are slightly different for systems with DDR | ||
42 | * DRAM or regular SDRAM devices. If SDRAM is used in the system, the | ||
43 | * SDRAM will still be accessible in direct-run mode. In DDR based systems, | ||
44 | * a transistion to direct-run mode will stop all DDR accesses (no clocks). | ||
45 | * Because of this, the code to switch power modes and the code to enter | ||
46 | * and exit DRAM self-refresh modes must not be executed in DRAM. A small | ||
47 | * section of IRAM is used instead for this. | ||
48 | * | ||
49 | * Suspend is handled with the following logic: | ||
50 | * Backup a small area of IRAM used for the suspend code | ||
51 | * Copy suspend code to IRAM | ||
52 | * Transfer control to code in IRAM | ||
53 | * Places DRAMs in self-refresh mode | ||
54 | * Enter direct-run mode | ||
55 | * Save state of HCLK_PLL PLL | ||
56 | * Disable HCLK_PLL PLL | ||
57 | * Enter halt mode - CPU and buses will stop | ||
58 | * System enters direct-run mode when an enabled event occurs | ||
59 | * HCLK PLL state is restored | ||
60 | * Run mode is entered | ||
61 | * DRAMS are placed back into normal mode | ||
62 | * Code execution returns from IRAM | ||
63 | * IRAM code are used for suspend is restored | ||
64 | * Suspend mode is exited | ||
