Hi folks,
This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset).
Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC.
Finally support for filter selection on alive banks is added, this is currently only enabled for gs101. The code path can be excercised using `echo mem > /sys/power/state`
regards,
Peter
