Andy Shevchenko e2d1812116 gpio: pcf857x: Make use of device properties
Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.

Add mod_devicetable.h include.

Andy Shevchenko 91a0192e90 gpio: pcf857x: Get rid of legacy platform data
Platform data is a legacy interface to supply device properties
to the driver. In this case we don't have in-kernel users for it.
Moreover it uses plain GPIO numbers which is no-no for a new code.

Just remove it for good.

Radu Rendec 64d2f4594e gpio: pcf857x: Implement get_multiple/set_multiple methods
This change allows the GPIO core to read/change multiple pins in a
single driver call and subsequent I2C transfer. It helps a lot with
PCF857x devices, since their I2C protocol always reads/changes all
existing pins anyway. Therefore, when the GPIO client code does a bulk
operation on multiple pins, the driver makes a single I2C transfer.

The regmap API supports IO port accessors so we can take advantage of

For the 104-idi-48, we get an IRQ register with some status information
and basic masking, but it's broken down by banks rather than individual
GPIO. There are six banks (8 GPIO lines each) that correspond to the
lower six bits of the IRQ register (bits 0-5):

    Base Address + 7 (Read): IRQ Status Register/IRQ Clear
        Bit 0-5: Respective Bank IRQ Statuses
        Bit 6: IRQ Status (Active Low)
        Bit 7: IRQ Enable Status

The regmap API supports IO port accessors so we can take advantage of

    Base Address +B (Read): Disable Interrupt
    Base Address +F (Read/Write): Clear Interrupt

Any write to 0xB will enable interrupts, while any read will disable
interrupts. Interrupts are cleared by a write to 0xF. There's no IRQ
status register, so software has to assume that if an interrupt is
raised then it was for the 104-DIO-48E device.

William Breathitt Gray 8978277c22 gpio: regmap: Always set gpio_chip get_direction
If you only have reg_dat_base set, then it is input-only; if you only
have reg_set_base set, then it is output-only. Thus, we can always set
gpio_chip get_direction to gpio_regmap_get_direction and return
GPIO_LINE_DIRECTION_IN/GPIO_LINE_DIRECTION_OUT given the respective
register base addresses configuration.

Andy Shevchenko 9eeaa60ead gpio: pca953x: Remove unused PCAL953X_OUT_CONF from pcal6534_recalc_addr()
First of all, PCAL953X_OUT_CONF is not used in the driver.
Second, it's not a per-bank register, it's a single for the
chip and should be handled differently anyway.

To avoid confusion, drop PCAL953X_OUT_CONF from pcal6534_recalc_addr().

Andy Shevchenko a87f901b59 gpio: pca953x: Clean up pcal6534_check_register()
The pcal6534_check_register() is a bit too verbose.
Clean up it, by deduplicating some operations and
switching to the modulo operation as on some architectures
/ and % can become a single assembly instruction.

Haibo Chen b1453d1eb9 gpio: pca953x: avoid logically dead code
The current code logic make the condition "else if (reg >= 0x54)"
can't be true, cause the dead code. So fix it to match the coder
expectation. This is reported by Coverity.

A remove callback just returning 0 is equivalent to no remove callback
at all. So drop the useless function.

Johan Hovold 908334ab0b gpiolib: use irq_domain_alloc_irqs()
Use the irq_domain_alloc_irqs() wrapper instead of the full
__irq_domain_alloc_irqs() interface, which was only intended for some
legacy (x86) use cases.
