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>; }; Signed-off-by: Wei Chen <Wei.Chen@csr.com> Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
