The Kconfig currently controlling compilation of this code is: drivers/gpio/Kconfig:config GPIO_STA2X11 drivers/gpio/Kconfig: bool "STA2x11/ConneXt GPIO support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

These chips seem to have a 9th GPIO block (thus supporting 72 GPIOs) which is configured through SuperIO register 0xd2 (output enable) and 0xd3 (simple I/O). This is also the reason why io_size is larger than on IT8728 / IT8732. Unfortunately I don't have hardware to test this 9th GPIO block. I am also not sure about not configuring the Simple I/O registers as the hardware I have only uses GPIO block 8. Reading back the values of 0xc0-0xc7 (as configured by the BIOS/EFI on my board) shows that all have 0xff set. Signed-off-by:

The interrupt for the corresponding pin is configured to trigger when the pin state changes compared to a preconfigured state (Bit set in INTCON). This state is set by setting/clearing the bit in DEFVAL. In the interrupt handler we need also to check if the bit in INTCON is set for level triggered interrupts. Signed-off-by:
