2020-06-30soc/amd/gpio, mb/{amd,google}: Configure pads using a single entry in GPIO ↵Furquan Shaikh
configuration table Currently, for Stoneyridge and Picasso mainboards, pads that are configured for SCI/SMI/WAKE need to have multiple entries in the configuration table - one for PAD_GPI and other for the special configuration that is required. This requires a very specific ordering of pads within the table and is prone to errors because of conflicting params provided to the different entries for the same pad. This also does not work very well with the concept of override GPIOs where the entry in base table is overridden with the first matched entry from the override table. This change updates the way GPIO configuration is handled for special routing like SCI/SMI/WAKE/DEBOUNCE by setting the control field of soc_amd_gpio structure in the macros performing these configurations. Also, program_gpios() is updated to perform a write to GPIO control register instead of read-modify-write. This is because mainboard is expected to provide only a single configuration entry for each pad within a given table. Thus, there is no need to preserve earlier configuration. Mainboards that were providing multiple entries for a single pad are updated accordingly.

Interrupt enabling macros are renamed to GPIO_INT_ENABLE_. _INT_ is dropped from pad filtering macros because the filtering applies to the input signal irrespective of how it is routed.

However, the naming for these flags is not consistent across event triggers and special configurations.

In the following CLs, more changes will be made to drop some of the special flags which are not really required.

The banked GPIO functionality in the AcpiMmio block has been consistent since the Mullins product. Move the basic support into a common directory. Each product's pin availability, MUXes, and other details must remain specific to the product. The relocated source also drops the weak configure_gevent_smi() that reports SMI is not available. The stoneyridge port relies on SMI to do its initialization, similar to modern soc/intel devices. This is the plan for future soc/amd ports, so make a missing function a build error instead of a runtime warning.
