2019-08-20pinctrl: stmfx: Use the callback to populate valid_maskLinus Walleij
This makes use of the existing callback to populate the valid mask instead of iteratively setting it up during probe.

2019-08-20gpio: Pass mask and size with the init_valid_mask()Linus Walleij
It is more helpful for drivers to have the affected fields directly available when we use the callback to set up the valid mask. Change this and switch over the only user (MSM) to use the passed parameters. If we do this we can also move the mask out of publicly visible struct fields.

2019-08-15gpio: thunderx: Switch to GPIOLIB_IRQCHIPLinus Walleij
Use the new infrastructure for hierarchical irqchips in gpiolib. The major part of the rewrite was dues to the fact that the driver was passing around a per-irq pointer to struct thunderx_line * data container, and the central handlers will assume struct gpio_chip * to be passed to we need to use the hwirq as index to look up the struct thunderx_line * for each IRQ. The pushing and pop:ing of the irqdomain was confusing because I've never seen this before, but I tried to replicate it as best I could. I have no chance to test or debug this so I need help.

2019-08-15gpio: Add support for hierarchical IRQ domainsLinus Walleij
Hierarchical IRQ domains can be used to stack different IRQ controllers on top of each other. Bring hierarchical IRQ domains into the GPIOLIB core with the following basic idea: Drivers that need their interrupts handled hierarchically specify a callback to translate the child hardware IRQ and IRQ type for each GPIO offset to a parent hardware IRQ and parent hardware IRQ type. Users have to pass the callback, fwnode, and parent irqdomain before calling gpiochip_irqchip_add(). We use the new method of just filling in the struct gpio_irq_chip before adding the gpiochip for all hierarchical irqchips of this type. The code path for device tree is pretty straight-forward, while the code path for old boardfiles or anything else will be more convoluted requireing upfront allocation of the interrupts when adding the chip. One specific use-case where this can be useful is if a power management controller has top-level controls for wakeup interrupts. In such cases, the power management controller can be a parent to other interrupt controllers and program additional registers when an IRQ has its wake capability enabled or disabled. The hierarchical irqchip helper code will only be available when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using this should select or depend on that symbol. When using hierarchical IRQs, the parent interrupt controller must also be hierarchical all the way up to the top interrupt controller wireing directly into the CPU, so on systems that do not have this we can get rid of all the extra code for supporting hierarchical irqs.

2019-07-20dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

2019-07-20dt-bindings: Ensure child nodes are of type 'object'Rob Herring
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.
