Move the pin description to a driver specific to be. This is one more step toward retiring pinctrl-sunxi-pins.h that used to define all the pins for all the Allwinner SoCs in a single header, that would have in turn result in having these structures in the final binary as many times as the header was included.

The previous code was calling of_iomap, which doesn't do any resource management, and doesn't call request_mem_region either. Use devm_ioremap_resource that do both. Signed-off-by: -

We previously had an evergrowing (and exhaustive) list of the pins that could be used on any Allwinner SoCs. These defines were then used by each pinctrl driver to declare the list of functions for this pin. Since it's pretty much all boilerplate, we can remove it just by a single macro. Signed-off-by: -

The pins description structure were declared as const, but the of_device_id data magic was losing it silently. Make sure we have it on both sides. And now that we're using const, we can also remove the useless cast in probe. Signed-off-by:

This commit extends the pinctrl mvebu logic with a new driver to cover Orion5x SoC. It supports the definitions for the 5181l, 5182 and 5281 variants of Orion5x, which are the three ones supported by the old style MPP code in arch/arm/mach-orion5x/. Signed-off-by:

In some cases it is nice to be able to simply control a gpio output via the PIN_CONFIG_OUTPUT option without having a driver control it. Thus add support for it to the rockchip pinctrl driver. Signed-off-by:

Till now pinconf_get only set the argument value into the config parameter effectively removing the actual config param value. As other pinctrl drivers do, it might be nicer to keep the config param intact. Therefore construct a real pinconfig value from param and arg in pinconf_get Signed-off-by:

The sirfsoc_irqchip_to_bank() is obviously misnamed, as it is not converting an irqchip to a bank but converts a gpiochip to a bank so rename it sirfsoc_gpiochip_to_bank(). Acked-by:

pin_to_mask expects a bank pin number. So do not add the chip base.

The range of npins and function ID values is small enough to fit into a u8. Use this type rather than unsigned to shrink the pinmux data tables. Signed-off-by:
-
Stephen Warren authored
The fsafe value in the pingroup data tables is only used to implement tegra_pinctrl_disable(). The only reason this function is called is when dynamically switching between pinmux states, i.e. when disabling the old state before programming the new state. It's simpler to have the new target state define the expected value of each pin (and all current DTs do that). This also gives more flexibility, since it allows individual boards explicit control over the "inactive" mux function for each pin, rather than requiring it to be an SoC-specific value. Assuming this, we can get rid of the fsafe value from the driver completely, thus saving some more space in the driver tables. While re-writing the content of tegra124_pingroups[], fix the indentation to use a TAB instead of spaces. Signed-off-by:

Any SoC which supports the einput, odrain, lock, ioreset, or rcv_sel options has the relevant HW register fields in the same register as the mux function selection. Similarly, the drvtype option is always in the drive register, if it is supported at all. Hence, we don't need to have struct *_reg fields in the pin group table to define which register and bank to use for those options. Delete this to save space in the driver's data tables. However, many of those options are not supported on all SoCs, or not supported on some pingroups. We need a way to detect when they are supported. Previously, this was indicated by setting the struct *_reg field to -1. With the struct *_reg fields removed, we use the struct *_bit fields for this purpose instead. The struct *_bit fields need to be expanded from 5 to 6 bits in order to store a value outside the valid HW bit range of 0..31. Even without removing the struct *_reg fields, we still need to add code to validate the struct *_bit fields, since some struct *_bit fields were already being set to -1, without an option-specific struct *_reg field to "guard" them. In other words, before this change, the pinmux driver might allow some unsupported options to be written to HW. Signed-off-by:

When using a group only pinctrl driver, which does not have any information on the pins it is useless to define a get_group_pins always returning an empty list of pins. When not using get_group_pin[1], a driver must implement it so pins = NULL and num_pins = 0. This patch makes it the default behaviour if not defined in the pinctrl driver when used in pinmux enable and disable funtions and in pinctrl_groups_show. It also adds a check in pinctrl_get_group_pins and return -EINVAL if not defined. This function is called in the gpiolib when adding when pingroup range. It cannot be used if no group is defined, so this seams reasonable.
