gpio: intel-mid: Remove driver for deprecated platform

2021-01-25T18:05:31+00:00

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. 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 Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.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.

gpio: intel-mid: Move hardware initialization to callback

2019-10-14T23:18:51+00:00

The driver wants to initialize related registers before IRQ chip will be added. That's why move it to a corresponding callback. It also fixes the NULL pointer dereference.

gpio: intel-mid: Pass irqchip when adding gpiochip

2019-08-12T17:39:26+00:00

We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. For chained irqchips this is a pretty straight-forward conversion.

gpio: intel-mid: Convert to use SPDX identifier

2018-12-07T15:34:07+00:00

Reduce size of duplicated comments by switching to use SPDX identifier. No functional change. Signed-off-by: Andy Shevchenko

gpio: intel-mid: Remove linux/module.h and sort headers

2018-12-07T15:34:06+00:00

There is no need to include linux/module.h when at the same time we include linux/init.h. Remove redundant inclusion. While here, remove no-op macro and sort header block alphabetically for easy maintenance. Signed-off-by: Andy Shevchenko

gpio-intel-mid: Delete an error message

2018-02-22T14:29:05+00:00

Omit an extra message for a memory allocation failure in this function. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Andy Shevchenko Signed-off-by: Linus Walleij

gpio: Move irqdomain into struct gpio_irq_chip

2017-11-08T13:06:21+00:00

In order to consolidate the multiple ways to associate an IRQ chip with a GPIO chip, move more fields into the new struct gpio_irq_chip. Signed-off-by: Thierry Reding Acked-by: Grygorii Strashko Signed-off-by: Linus Walleij

gpio: intel-mid: Fix build warning when !CONFIG_PM

2017-01-26T09:00:20+00:00

The only usage of function intel_gpio_runtime_idle() is here (in the same file): static const struct dev_pm_ops intel_gpio_pm_ops = { SET_RUNTIME_PM_OPS(NULL, NULL, intel_gpio_runtime_idle) }; And when CONFIG_PM is not set, the macro SET_RUNTIME_PM_OPS expands to nothing, causing the following compiler warning: drivers/gpio/gpio-intel-mid.c:324:12: warning: ‘intel_gpio_runtime_idle’ defined but not used [-Wunused-function] static int intel_gpio_runtime_idle(struct device *dev) Fix it by annotating the function with __maybe_unused.
