pinctrl: samsung: add support for gs101 wakeup mask programming
gs101 differs to other currently supported SoCs in that it has 3 wakeup
mask registers for the 67 external wakeup interrupt pins in alive and
far_alive.
EINT_WAKEUP_MASK 0x3A80 EINT[31:0]
EINT_WAKEUP_MASK2 0x3A84 EINT[63:32]
EINT_WAKEUP_MASK3 0x3A88 EINT[66:64]
Add gs101 specific callbacks and a dedicated gs101_wkup_irq_chip struct to
handle these differences.
The current wakeup mask with upstream is programmed as
WAKEUP_MASK0[0x3A80] value[0xFFFFFFFF]
WAKEUP_MASK1[0x3A84] value[0xF2FFEFFF]
WAKEUP_MASK2[0x3A88] value[0xFFFFFFFF]
Which corresponds to the following wakeup sources:
gpa7-3 vol down
gpa8-1 vol up
gpa10-1 power
gpa8-2 typec-int
