2017-09-04Merge tag 'asoc-v4.14' of ↵Takashi Iwai
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.14 This is quite a large release by volume of patches and diff, a lot of that is mechanical cleanup patches but it's great to also see a range of vendors actively working on adding new features and fixing issues in their drivers. Intel and Realtek have been especially active here. - Continued work towards moving everything to the component model from Morimoto-san. - Use of devres for jack detection GPIOs, eliminating some potential resource leaks. - Jack detection support for Qualcomm MSM8916. - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson WM8523.

2017-09-04irqchip: mips-gic: Let the core set struct irq_common_data affinityPaul Burton
gic_set_affinity() manually copies the provided cpumask to the struct irq_common_data affinity field, returning IRQ_SET_MASK_OK_NOCOPY in order to prevent the core code from doing that. We can instead simply let the core code do it for us, by returning IRQ_SET_MASK_OK instead of IRQ_SET_MASK_OK_NOCOPY & doing the copy ourselves.

2017-09-04irqchip: mips-gic: Use cpumask_first_and() in gic_set_affinity()Paul Burton
Currently in gic_set_affinity() we calculate a temporary cpumask holding the intersection of the provided cpumask & the CPUs that are online, then we call cpumask_first twice on it to find the first such CPU. Since we don't need the temporary cpumask for anything else & we only care about the first CPU that's both online & in the provided cpumask, we can instead use cpumask_first_and to find that CPU & drop the temporary mask.

2017-09-04irqchip: mips-gic: Clean up mti, reserved-cpu-vectors handlingPaul Burton
When parsing mti,reserved-cpu-vectors we generate a mask of all bits that have been declared reserved, the loop through starting from bit 2 to find one that isn't reserved (ie. is zero). This patch accomplishes the same task more simply by: - Inititialising the reserved mask to 0x3 (ie. the 2 software interrupts). This means we don't need to skip them later as the loop previously has. - Replacing the loop checking for zero bits with find_first_zero_bit, which fits our needs now that the 2 software interrupts are marked reserved. This requires that the type of reserved is changed to unsigned long so that it's suitable for use with bitmap functions. - Replacing the magic number 8 with the hamming weight of the ST0_IM field - ie. the number of bits that a MIPS CPU has for interrupt inputs. This is still a compile-time constant 8, but makes it clearer why it's 8.

2017-09-04irqchip: mips-gic: Use pcpu_masks to avoid reading GIC_SH_MASK*Paul Burton
This patch avoids the need to read the GIC_SH_MASK* registers when decoding shared interrupts by setting & clearing the interrupt's bit in the appropriate CPU's pcpu_masks entry when masking or unmasking the interrupt. This effectively means that whilst an interrupt is masked we clear its bit in all pcpu_masks, which causes gic_handle_shared_int() to ignore it on all CPUs without needing to check GIC_SH_MASK*. In essence, we add a little overhead to masking or unmasking interrupts but in return reduce the overhead of the far more common task of decoding interrupts.

The __gic_init() function is only called from gic_of_init() now that the non-DT path has been removed. In order to simplify the code & aid readability, fold __gic_init() into gic_of_init(). This provides us with the ability to return an error code, which __gic_init() was previously unable to do.

2017-09-04irqchip: mips-gic: Remove gic_set_dual_edge()Paul Burton
Remove the gic_set_dual_edge() function in favour of using the new change_gic_dual() accessor function which provides equivalent functionality. This also allows us to remove the gic_update_bits() function which gic_set_dual_edge() was the last user of, along with the GIC_INTR_OFS() & GIC_INTR_BIT() macros.

2017-09-04irqchip: mips-gic: Drop gic_(re)set_mask() functionsPaul Burton
The gic_set_mask() & gic_reset_mask() functions are now no more convenient to call than the write_gic_smask() or write_gic_rmask() accessor functions. Remove the layer of abstraction.

2017-09-04irqchip: mips-gic: Simplify gic_local_irq_domain_map()Paul Burton
Simplify gic_local_irq_domain_map() by: - Moving the check for invalid IRQs outside of the loop. - Moving the decision about whether to use gic_cpu_pin or timer_cpu_pin outside of the loop. - Using the new write_gic_vo_map() accessor function to avoid the need to handle each map register separately.

2017-09-04MIPS: Add __ioread64_copyPaul Burton
We currently have __ioread32_copy, __iowrite32_copy & __iowrite64_copy helpers in lib/iomap_copy.c. This patch adds __ioread64_copy to round out the set, allowing copies from I/O memory using 32 or 64 bit reads.

2017-09-04MIPS: CPS: Read GIC_VL_IDENT directly, not via irqchip driverPaul Burton
Rather than calling the gic_read_local_vp_id() function from the GIC irqchip driver, call read_gic_vl_ident() to read the GIC_VL_IDENT register directly. This will allow us to remove gic_read_local_vp_id() from the irqchip driver in a further patch, since that driver doesn't actually care about the register's value.
