pinctrl: qcom: sm8250: Specify PDC map

2020-11-10T13:57:05+00:00

Specify the PDC mapping for SM8250, so that gpio interrupts are
propertly mapped to the wakeup IRQs of the PDC.

pinctrl: qcom: Move clearing pending IRQ to .irq_request_resources callback

2020-11-10T13:30:42+00:00

When GPIOs that are routed to PDC are used as output they can still latch
the IRQ pending at GIC. As a result the spurious IRQ was handled when the
client driver change the direction to input to starts using it as IRQ.

Currently such erroneous latched IRQ are cleared with .irq_enable callback
however if the driver continue to use GPIO as interrupt and invokes
disable_irq() followed by enable_irq() then everytime during enable_irq()
previously latched interrupt gets cleared.

This can make edge IRQs not seen after enable_irq() if they had arrived
after the driver has invoked disable_irq() and were pending at GIC.

Move clearing erroneous IRQ to .irq_request_resources callback as this is
the place where GPIO direction is changed as input and its locked as IRQ.

While at this add a missing check to invoke msm_gpio_irq_clear_unmask()
from .irq_enable callback only when GPIO is not routed to PDC.

pinctrl: amd: use higher precision for 512 RtcClk

2020-11-10T13:19:10+00:00

RTC is 32.768kHz thus 512 RtcClk equals 15625 usec. The documentation
likely has dropped precision and that's why the driver mistakenly took
the slightly deviated value.

pinctrl: amd: fix incorrect way to disable debounce filter

2020-11-10T13:18:37+00:00

The correct way to disable debounce filter is to clear bit 5 and 6
of the register.

pinctrl: aspeed: Fix GPI only function problem.

2020-11-05T14:32:58+00:00

Some gpio pin at aspeed soc is input only and the prefix name of these
pin is "GPI" only.
This patch fine-tune the condition of GPIO check from "GPIO" to "GPI"
and it will fix the usage error of banks D and E in the AST2400/AST2500
and banks T and U in the AST2600.

pinctrl: mcp23s08: Print error message when regmap init fails

It is useful for debugging to have the error message printed
when regmap initialisation fails. Add it to the driver.

pinctrl: mcp23s08: Use full chunk of memory for regmap configuration

2020-11-05T10:30:17+00:00

It appears that simplification of mcp23s08_spi_regmap_init() made
a regression due to wrong size calculation for dev_kmemdup() call.
It misses the fact that config variable is already a pointer, thus
the sizeof() calculation is wrong and only 4 or 8 bytes were copied.

Fix the parameters to devm_kmemdup() to copy a full chunk of memory.

Remove totally irq mappings create in probe, the gpio irq mapping will
be created when do
    gpio_to_irq ->
        rockchip_gpio_to_irq ->
            irq_create_mapping

This patch can speed up system boot on, also abandon many unused irq
