通过下面的函数操作，将生成如下的图表

int __init am33xx_mux_init(struct omap_board_mux *board_subset){return omap_mux_init("core", 0, AM33XX_CONTROL_PADCONF_MUX_PBASE,AM33XX_CONTROL_PADCONF_MUX_SIZE, am33xx_muxmodes,NULL, board_subset, NULL);}

通过如下函数获得寄存器便宜并设置

static void setup_pin_mux(struct pinmux_config *pin_mux){int i;for (i = 0; pin_mux->string_name != NULL; pin_mux++)omap_mux_init_signal(pin_mux->string_name, pin_mux->val);}

该函数首先找到

struct omap_mux_partition partition

再通过该结构找到（通过名字判断）

struct omap_mux_entry

再通过该结构找到

struct omap_mux mux

在该mux中包含了寄存器便宜的值，函数通过partition的基地址加上此偏移值设置相应寄存器
