With real-time preemption, regmap functions cannot be used in the implementation of irq_chip since they use spinlocks which may sleep. Move the setting of the mux for IRQs to an irq_bus_sync_unlock handler where we are allowed to sleep.

We need to avoid calling regmap functions from irq handlers, so the next commit is going to move the call to rockchip_set_mux() into an irq_bus_sync_unlock handler. But we can't return an error from there so we still need to check the settings from rockchip_irq_set_type() and we will use this new rockchip_verify_mux() function from there.

On some Cherry Trail devices the ASL uses the GMMR GPIO to access GPIOs so as to serialize MMIO accesses to GPIO registers with the OS, because: "Due to a silicon issue, a shared lock must be used to prevent concurrent accesses across the 4 GPIO controllers. See Intel Atom Z8000 Processor Series Specification Update (Rev. 005), errata #CHT34, for further information." This commit adds support for this opregion, this fixes a number of ASL errors on my Ezpad mini3 tablet and makes the otg port device/host muxing which is controlled in firmware on this model work properly.

Currently we are trying to enable/disable the clk of irq's gpio bank when unmask/mask irq. But the kernel's "lazy disable approach" will skip masking irq when the irq chip doesn't support irq_disable ops.

The sunxi pinctrl driver currently implement an irq_chip for handling interrupts; due to how irq_chip handling is done, it's necessary for the irq_chip methods to be invoked from hardirq context, even on a a real-time kernel. Because the spinlock_t type becomes a "sleeping" spinlock w/ RT kernels, it is not suitable to be used with irq_chips. A quick audit of the operations under the lock reveal that they do only minimal, bounded work, and are therefore safe to do under a raw spinlock.

由 Rick Altherr 提交于
Port D and port E GPIO loopback modes are commonly enabled via hardware straps for use with front-panel buttons. When the BMC is powered off or fails to boot, the front-panel buttons are directly connected to the host chipset via the loopback to allow direct power-on and reset control. Once the BMC has booted, the loopback mode must be disabled for the BMC to take over control of host power-on and reset. Disabling these loopback modes requires writing to the hardware strap register which violates the current design of assuming the system designer chose the strap settings for a specific reason and they should be treated as read-only. Only the two bits of the strap register related to these loopback modes are allowed to be written and comments have been added to explain why.
