+ * @spec_pull_set: Each SoC may have special pins for pull up/down setting,
+ * these pins' pull setting are very different, they have separate pull
+ * up/down bit, R0 and R1 resistor bit, so they need special pull setting.
+ * If special setting is success, this should return 0, otherwise it should

+ * @spec_ies_smt_set: Some pins are irregular, their input enable and smt
+ * control register are discontinuous, but they are mapping together. That
+ * means when user set smt, input enable is set at the same time. So they
+ * also need special control. If special control is success, this should
+ * return 0, otherwise return non-zero value.
+ * @spec_pinmux_set: In some cases, there are two pinmux functions share
+ * the same value in the same segment of pinmux control register. If user
+ * want to use one of the two functions, they need an extra bit setting to
+ * select the right one.
+ * @spec_dir_set: In very few SoCs, direction control registers are not
+ * arranged continuously, they may be cut to parts. So they need special
+ * dir setting.
+
+ * @dir_offset: The direction register offset.
+ * @pullen_offset: The pull-up/pull-down enable register offset.
+ * @pinmux_offset: The pinmux register offset.
+ *
+ * @type1_start: Some chips have two base addresses for pull select register,
+ * that means some pins use the first address and others use the second. This
+ * member record the start of pin number to use the second address.
+ * @type1_end: The end of pin number to use the second address.
+ *
+ * @port_shf: The shift between two registers.
+ * @port_mask: The mask of register.
+ * @port_align: Provide clear register and set register step.
