pinctrl: atlas7: adjust pin groups of atlas7 nanddisk
Remove write-protect and chip-selector pins from nand pin group.
And then create two separate pin groups for these two pin.
So the nand driver can choose correct pin groups as board desgin:
For example:
1. nand without wp&cs:
nand@17050000 {
pinctrl-0 = <&nd_df_basic_pmx>;
};
2. nand with wp
nand@17050000 {
pinctrl-0 = <&nd_df_basic_pmx &nd_df_wp_pmx>;
};
3. nand with cs:
nand@17050000 {
pinctrl-0 = <&nd_df_basic_pmx &nd_df_cs_pmx>;
};
4. nand with wp&cs:
nand@17050000 {
pinctrl-0 = <&nd_df_basic_pmx &nd_df_wp_pmx &nd_df_cs_pmx>;
};
