24 * Versatile Express implementation of @ref kbase_cpu_clk_speed_func.
26 int kbase_get_vexpress_cpu_clock_speed(u32 *cpu_clock);
29 * kbase_get_platform_logic_tile_type - determines which LogicTile type
30 * is used by Versatile Express
32 * When platform_config build parameter is specified as vexpress, i.e.,
33 * platform_config=vexpress, GPU frequency may vary dependent on the
34 * particular platform. The GPU frequency depends on the LogicTile type.
36 * This function is called by kbase_common_device_init to determine
37 * which LogicTile type is used by the platform by reading the HBI value
38 * of the daughterboard which holds the LogicTile:
40 * 0x192 HBI0192 Virtex-5
41 * 0x217 HBI0217 Virtex-6
42 * 0x247 HBI0247 Virtex-7
44 * Return: HBI value of the logic tile daughterboard, zero if not accessible
