Up to now stmpe_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway. Signed-off-by:

The resource_size defines that: res->end - res->start + 1; The origin original code is: sysmgr_config.max_register = res->end - res->start - 3; So, the correct fix is that: sysmgr_config.max_register = resource_size(res) - 4; Fixes: d12edf96 ("mfd: altera-sysmgr: Use resource_size function on resource object") Signed-off-by:

The X-Powers AXP PMICs feature a GPIO Controller supported by Linux thanks to its device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.

The Arizona driver has both some devices which only have an I2C interface and some which only have a SPI interface. Currently both of these share an of_match table, but this means inapproriate compatibles are available for each interface. Tidy this up by creating a table for each interface listing only the appropriate compatibles. Reported-by:

PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the irq_set_chained_handler_and_data() results in warnings from the GPIOLIB (see 461c1a7d ("gpiolib: override irq_enable/disable")) as in this path the IRQ resources are not allocated (and thus the corresponding GPIO is not marked as used for the IRQ. Use request_irq so that the IRQ resources are proprely setup.

Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 14577/77836 datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and charger driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.
