[PATCH v2 2/2] pinctrl: Allow indicating loss of pin states during low-power

2017-11-02 Thread Florian Fainelli
Some platforms (e.g: Broadcom STB: BMIPS_GENERIC/ARCH_BRCMSTB) will lose their register contents when entering their lower power state. In such a case, the pinctrl-single driver that is used will not be able to restore the power states without telling the core about it and having
