pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB

2020-10-29T08:57:34+00:00

[ Upstream commit 513034d8b089b9a49dab57845aee70e830fe7334 ] When PINCTRL_BCM2835 is enabled and GPIOLIB is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for GPIOLIB_IRQCHIP Depends on [n]: GPIOLIB [=n] Selected by [y]: - PINCTRL_BCM2835 [=y] && PINCTRL [=y] && OF [=y] && (ARCH_BCM2835 [=n] || ARCH_BRCMSTB [=n] || COMPILE_TEST [=y]) The reason is that PINCTRL_BCM2835 selects GPIOLIB_IRQCHIP without depending on or selecting GPIOLIB while GPIOLIB_IRQCHIP is subordinate to GPIOLIB. Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

pinctrl: iproc: allow for error from platform_get_irq()

platform_get_irq() can return an error code. Allow for this when getting the irq.

pinctrl: ns2: Fix off by one bugs in ns2_pinmux_enable()

2019-10-04T22:13:25+00:00

The pinctrl->functions[] array has pinctrl->num_functions elements and the pinctrl->groups[] array is the same way. These are set in ns2_pinmux_probe(). So the > comparisons should be >= so that we don't read one element beyond the end of the array.

pinctrl: bcm: remove redundant assignment to pointer log

2019-09-12T09:25:53+00:00

The pointer log is being initialized with a value that is never read and is being re-assigned a little later on. The assignment is redundant and hence can be removed.

pinctrl: iproc-gpio: Handle interrupts for multiple instances

2019-09-11T09:43:04+00:00

When multiple instance of iproc-gpio chips are present, a fix up message[1] is printed during the probe of second and later instances. This issue is because driver sharing same irq_chip data structure among multiple instances of driver. Fix this by allocating irq_chip data structure per instance of iproc-gpio. [1] fix up message addressed by this patch [ 7.862208] gpio gpiochip2: (689d0000.gpio): detected irqchip that is shared with multiple gpiochips: please fix the driver.

pinctrl: bcm2835: Pass irqchip when adding gpiochip

2019-08-26T11:21:53+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. The BCM2835 has multiple parents so let's exploit the new facility in the GPIO_IRQCHIP to actually deal with multiple parents.
