x86: tangier: pinmux: add API to configure protected pins
This API is going to be used to configure some pins that are protected for simple modification. It's not a comprehensive pinctrl driver but can be turned into one when we need this in the future. Now it is planned to be used only in one place. So that's why I decided not to pollute the codebase with a full-blown pinctrl-merrifield nobody will use. This driver reads corresponding fields in DT and configures pins accordingly. The "protected" flag is used to distinguish configuration of SCU-owned pins from the ordinary ones. The code has been adapted from Linux work done by Andy Shevchenko in pinctrl-merrfifield.c Signed-off-by: Georgii Staroselskii <georgii.staroselskii@emlid.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> [bmeng: fix build warning] Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
