Hence, since then, the MX35 3DS BOARD MC9S08DZ60 GPIO functions are dead code as its config GPIO_MC9S08DZ60 depends on the config MACH_MX35_3DS. Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs: MACH_MX35_3DS Referencing files: drivers/gpio/Kconfig Remove the obsolete MX35 3DS BOARD MC9S08DZ60 GPIO functions.

This allows a guest VM running Linux to access GPIO lines provided by the host. It supports all basic operations, except interrupts for the GPIO lines.

Each bank has a set of registers for 32 GPIOs, with support for edge-triggered interrupts. Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most registers pack one bit per GPIO, except for the IMR register, which packs two bits per GPIO (AB-CD). Although the byte order is currently assumed to have port A..D at offset 0x0..0x3, this has been observed to be reversed on other, Lexra-based, SoCs (e.g. RTL8196E/97D/97F). Interrupt support is disabled for the fallback devicetree-compatible 'realtek,otto-gpio'. This allows for quick support of GPIO banks in which the byte order would be unknown. In this case, the port ordering in the IMR registers may not match the reversed order in the other registers (DCBA, and BA-DC or DC-BA).

The IC has two GPO pins but only one is properly documented in the data-sheet. The driver exposes by default only the documented GPO. The second GPO is connected to E5 pin and is marked as GND in the data-sheet. Control for this undocumented pin can be enabled using a special DT property. This driver is derived from work by Peter Yang <yanglsh@embest-tech.com> although not so much of the original is left.

There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely. Moreover this code duplicates gpio-pxa since the IP has been derived from XScale implementation. If anybody wants to resurrect this it has to be part of gpio-pxa.c.
