During an audit for non-modular drivers using modular infrastructure this driver showed up. But rather than demodularize it, Laxman indicated that it would be prefereable to instead convert the driver option to tristate. This does that, and confirms that it will compile and modpost as such. However, since I do not have the hardware to confirm that no new runtime issues exist when modular, that remains untested.

When pinctrl_get() is called for a device, it will return a valid handle even if the device itself has no pinctrl state entries defined in device-tree. This is caused by the function pinctrl_dt_to_map() which will return success even if the first pinctrl state, 'pinctrl-0', is not found in the device-tree node for a device. According to the pinctrl device-tree binding documentation, pinctrl states must be numbered starting from 0 and so 'pinctrl-0' should always be present if a device uses pinctrl and therefore, if 'pinctrl-0' is not present it seems valid that we should not return a valid pinctrl handle. Fix this by returning an error code if the property 'pinctrl-0' is not present for a device. Signed-off-by:

The pinctrl-intel needs to use request_irq() instead of chained interrupt handling because it shares the interrupt with multiple GPIO host controllers found on Intel CPUs. In -rt all such interrupts are forced to run in thread context which triggers following warning: WARNING: CPU: 0 PID: 530 at kernel/irq/handle.c:151 handle_irq_event_percpu+0x23d/0x240 irq 348 handler irq_default_primary_handler+0x0/0x10 enabled interrupts Modules linked in: CPU: 0 PID: 530 Comm: irq/14-INT3452: Not tainted 4.6.2-rt5 #1060 0000000000000000 ffff88007a257c98 ffffffff812d8494 ffff88007a257ce8 0000000000000000 ffff88007a257cd8 ffffffff8105e554 000000977a257d90 ffff88007a37a380 000000000000015c 0000000000000002 0000000000000000 Call Trace: [<ffffffff812d8494>] dump_stack+0x4f/0x6b [<ffffffff8105e554>] __warn+0xe4/0x100 [<ffffffff8105e5bf>] warn_slowpath_fmt+0x4f/0x60 [<ffffffff810b18f0>] ? __synchronize_hardirq+0x60/0x60 [<ffffffff810b17fd>] handle_irq_event_percpu+0x23d/0x240 [<ffffffff810b1862>] handle_irq_event+0x62/0x90 [<ffffffff810b4e1f>] handle_edge_irq+0x8f/0x190 [<ffffffff810b0d82>] generic_handle_irq+0x22/0x30 [<ffffffff81307abc>] intel_gpio_irq+0xdc/0x150 [<ffffffff810b2293>] irq_forced_thread_fn+0x23/0x70 [<ffffffff810b250b>] irq_thread+0x13b/0x1d0 [<ffffffff8167b844>] ? __schedule+0x2e4/0x5a0 [<ffffffff810b2270>] ? irq_finalize_oneshot.part.37+0xd0/0xd0 [<ffffffff810b25a0>] ? irq_thread+0x1d0/0x1d0 [<ffffffff810b23d0>] ? wake_threads_waitq+0x30/0x30 [<ffffffff8107e624>] kthread+0xd4/0xf0 [<ffffffff8167ec27>] ? _raw_spin_unlock_irq+0x17/0x40 [<ffffffff8167f592>] ret_from_fork+0x22/0x40 [<ffffffff8107e550>] ? kthread_worker_fn+0x190/0x190 The handle_irq_event_* functions (and I suppose generic_handle_irq()) is expected to be called with interrupts disabled and they rightfully complain here because we run in thread context with interrupts enabled. Fix this by adding IRQF_NO_THREAD flag when the master interrupt is requested. This prevents forced threading of the interrupt used by the GPIO host controllers. Reported-by:

This causes might_sleep() to trigger. Fix this by converting the normal spinlock to a raw_spinlock. Reported-by:

drivers/pinctrl/bcm/Makefile properly builds individual drivers based on their respective Kconfig symbols. ARCH_BCM is currently a menuconfig option from arch/arm/mach-bcm/Kconfig, which is fine, but prevents ARM64 platforms which do not have such menuconfig option from building their pinctrl drivers, so let's get rid of that dependency.
