30 * @enabled: refcount. positive if enabled, zero if disabled
31 * @get_rate: custom callback for getting the clock rate

37 * (used on u8500v1)
38 * @prcmu_cg_bit: bit in the combined enable/disable register (used on
39 * u8500v1)
40 * @prcmu_cg_mgt: address of the enable/disable register (used on
41 * u8500ed)
42 * @cluster: peripheral cluster number
43 * @prcc_bus: bit for the bus clock in the peripheral's CLKRST
44 * @prcc_kernel: bit for the kernel clock in the peripheral's CLKRST.
45 * -1 if no kernel clock exists.
46 * @parent_cluster: pointer to parent's cluster clk struct
47 * @parent_periph: pointer to parent's peripheral clk struct
48 *
49 * Peripherals are organised into clusters, and each cluster has an associated
50 * bus clock. Some peripherals also have a parent peripheral clock.
51 *
52 * In order to enable a clock for a peripheral, we need to enable:
53 * (1) the parent cluster (bus) clock at the PRCMU level
54 * (2) the parent peripheral clock (if any) at the PRCMU level
55 * (3) the peripheral's bus & kernel clock at the PRCC level
56 *
57 * (1) and (2) are handled by defining clk structs (DEFINE_PRCMU_CLK) for each
58 * of the cluster and peripheral clocks, and hooking these as the parents of
59 * the individual peripheral clocks.
60 *
61 * (3) is handled by specifying the bits in the PRCC control registers required
62 * to enable these clocks and modifying them in the ->enable and
63 * ->disable callbacks of the peripheral clocks (DEFINE_PRCC_CLK).
64 *
65 * This structure describes both the PRCMU-level clocks and PRCC-level clocks.
66 * The prcmu_* fields are only used for the PRCMU clocks, and the cluster,
67 * prcc, and parent pointers are only used for the PRCC-level clocks.
