Geert Uytterhoeven 412da8c722 pinctrl: renesas: Fix save/restore on SoCs with pull-down only pins ... If some bits in a pin Pull-Up control register (PUPR) control pin pull-down instead of pin pull-up, there are two pinmux_bias_reg entries: a first one with the puen field filled in, listing pins with pull-up functionality, and a second one with the pud field filled in, listing pins with pull-down functionality. On encountering the second entry, where puen is NULL, the for-loop terminates early, causing the remaining bias registers not to be saved/restored during PSCI system suspend. Fortunately this does not trigger on any supported system yet, as PSCI is only used on R-Car Gen3 and RZ/G2 systems, which all have separate pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers. Avoid this ever becoming a problem by treating pinmux_bias_reg.puen and pinmux_bias_reg.pud the same. Note that a register controlling both pull-up and pull-down pins would be saved and restored twice, which is harmless.
