gpio tracing was made configurable in 4.4-rc1 (commit ddd70280 ("tracing: gpio: Add Kconfig option for enabling/disabling trace events")). Since then it is the only event type that can be compiled conditionally. Given that there is only little overhead I don't understand the reasoning and I was annoyed more than once that gpio events were not available without recompiling. So drop the Kconfig symbol and make gpio events available unconditionally. Signed-off-by:

If a device is part of the wake-up path, it should indicate this by setting its power.wakeup_path field. This allows the genpd core code to keep the device enabled during system suspend when needed. As regulators powering devices are not handled by genpd, the driver handles these itself, and thus must skip regulator control when the device is part of the wake-up path. Signed-off-by:

Simple string comparisons are cheaper than DT lookups, as the latter involve taking a spinlock and traversing properties. Hence optimize quirk checks by postponing DT lookups after string comparisons. Signed-off-by:

The direction inversion semantics are now handled by simply using the registers for in/out available, no need to keep track of inversion semantics exmplicitly anymore. Reviewed-by:

During my regression testing I noticed the cadence GPIO driver fails on the latest gpio for-next tree. I think the reason is this patch: commit 96cd559817f2 ("Merge branch 'devel' into for-next") Here is a part of the test log: Loopback 8 -> 24 TESTING: gpio: 488: output direction PASSED TESTING: gpio: 504: input direction PASSED TESTING: gpio: 488: 0 PASSED TESTING: gpio: 488 -> 504: 0 PASSED TESTING: gpio: 488: 1 FAILED TESTING: gpio: 488 -> 504: 1 FAILED TESTING: gpio: 488: 0 PASSED TESTING: gpio: 488 -> 504: 0 PASSED It looks like the issue is that gc->bgpio_dir has changed its meaning. It used to be set to the register value (so it was being inverted). Now it's always set to 1 for output and 0 for input. However the bgpio_get_set functions were not updated. So they invert the bit again, which means a wrong register is being accessed. This patch fixes that by removing the unnecessary inversion. Signed-off-by: -

The gpio_set_config function creates a pinconf configuration for a given pinc_config_param. However, it always uses an arg of 0, which might not be a valid argument for a given param. A good example of that would be the bias parameters, where 0 means that the pull up or down resistor is null, and the pin is directly connected to VCC/GND. The framework uses in some other places the value 1 as a default argument to enable the pull resistor, so let's use the same one here. Signed-off-by:

clang warns about a tentative array definition in the gpio-omap driver: drivers/gpio/gpio-omap.c:1282:34: error: tentative array definition assumed to have one element [-Werror] static const struct of_device_id omap_gpio_match[]; It's best to just reorder the entire file to avoid forward declarations, which lets us use the regular declaration. To do this, the unnecessary CONFIG_OF check must also be removed. Signed-off-by:

The comment for this dbg_show says that it is supposed to return more than what the generic code is showing, including de-glitching. That's wrong because: - this chip does not support deglitching, - the code does not print anything extra compared to the generic handler, - its behavior is different because it skips unrequested GPIOs; the generic code prints their names if they're assigned There is an important difference, though. Previously, dbg_show would re-check some registers to see if they still match what the regmap thinks should be in there. This was semi-useful when develpoing the HW board because it immediately pointed to SPI wiring problem if a CS connection was missing (0xffs are easy to see). However, I do not think that this makes much sense -- and one could always do this in some other way if needed. Signed-off-by:
