These drivers are GPIO drivers, and the do not need to use the legacy header in <linux/gpio.h>, go directly for <linux/gpio/driver.h> instead. Replace any use of GPIOF_* with 0/1, these flags are for consumers, not drivers. Get rid of a few gpio_to_irq() users that was littering around the place, use local callbacks or avoid using it at all. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

By just moving the atmel_gpio_to_irq() and calling the internal function we can get rid of the driver calling back out into the deprecated external consumer API.

Ludovic Desroches authored
Sharing the same irqchip with multiple gpiochips is not a good practice. For instance, when installing hooks, we change the state of the irqchip. The initial state of the irqchip for the second gpiochip to register is then disrupted.

Smatch complains about this condition: if (has_config && num_pins >= 1) The "has_config" variable is either uninitialized or true. The "num_pins" variable is unsigned and we verified that it is non-zero on the lines before so we know "num_pines >= 1" is true. Really, we could just check "num_configs" directly and remove the "has_config" variable.

It looks like we parse the drive strength setting here, but never actually write it into the hardware to update it. Parse the setting and then write it at the end of the pinconf setting function so that it actually sticks in the hardware.

If you look at "pinconf-groups" in debugfs for ssbi-mpp you'll notice it looks like nonsense. The problem is fairly well described in commit 1cf86bc2 ("pinctrl: qcom: spmi-gpio: Fix pmic_gpio_config_get() to be compliant") and commit 05e0c828 ("pinctrl: msm: Fix msm_config_group_get() to be compliant"), but it was pointed out that ssbi-mpp has the same problem. Let's fix it there too. NOTE: in case it's helpful to someone reading this, the way to tell whether to do the -EINVAL or not is to look at the PCONFDUMP for a given attribute. If the last element (has_arg) is false then you need to do the -EINVAL trick. ALSO NOTE: it seems unlikely that the values returned when we try to get PIN_CONFIG_BIAS_PULL_UP will actually be printed since "has_arg" is false for that one, but I guess it's still fine to return different values so I kept doing that. It seems like another driver (ssbi-gpio) uses a custom attribute (PM8XXX_QCOM_PULL_UP_STRENGTH) for something similar so maybe a future change should do that here too.

Merge the code of the gpio-ingenic driver into the pinctrl-ingenic driver. The reason behind this, is that the same hardware block handles both pin config / muxing and GPIO. ingenic_gpio_probe() have been marked as __init, but for the most part, the code is the exact same as what it was in the gpio-ingenic driver.
