In this patch,we create a sirf dir, and let the old drivers/pinctrl/pinctrl-sirf.c = drivers/pinctrl/sirf/pinctrl-prima2.c + drivers/pinctrl/sirf/pinctrl-sirf.c drivers/pinctrl/sirf/pinctrl-atlas6.c is a newly created file for the pin layout of atlas6.

11/82] pinctrl: sink pinctrldev_list_mutex The pinctrldev_list_mutex is sinked into the functions that actually traverse the list and lock it there. The code makes much more sense in this way. All the callers are in non-performance critical paths and the code is way more readable this way. Also refactor the function get_pinctrl_dev_from_devname() to follow the design pattern of get_pinctrl_dev_from_of_node() which is slightly simpler.

Therefore this patch adds another config option to use this default pull-state for a pin where it is not possible to know or decide if the pin will be pulled up or down.

The number of these external interrupts are SoCs specific, but the current upper limit is 32. In order to work, the external interrupts' pins have to be muxed to a specific function to generate an interrupt. This patch adds the irqchip and the needed logic to use the PIO controller as an interrupt controller.

Earlier Rockchip SoCs seem to use similar mechanics for gpio handling so should be supportable with relative small changes. Pull handling on the rk3188 is currently a stub, due to it being a bit different to the earlier SoCs. Pinmuxing as well as gpio (and interrupt-) handling tested on a rk3066a based machine.

These pins have individually controlled pull-up, and group controlled schmitt, slew-rate, drive-strength, and power-on-start (pos). The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the ir_mod_stable_out and ir_mod_power_out functions respectively. If no function is set they remain in GPIO mode. These muxes can be overridden by requesting them as GPIOs.

For this reason we had: int pin_config_get(const char *dev_name, const char *name, unsigned long *config); int pin_config_set(const char *dev_name, const char *name, unsigned long config); int pin_config_group_get(const char *dev_name, const char *pin_group, unsigned long *config); int pin_config_group_set(const char *dev_name, const char *pin_group, unsigned long config); After the introduction of the pin control states that will control pins associated with devices, and its subsequent introduction to the device core, as well as the introduction of pin control hogs that can set up states on boot and optionally also at sleep, this direct pin control API is a thing of the past. As could be expected, it has zero in-kernel users. Let's delete this API and make our world simpler.

Currently no driver is using the generic pinconfig option for this, so the unit change is safe to do.
