pinctrl: pinctrl-rockchip: Fix a bunch of kerneldoc misdemeanours · e1524ea8

Lee Jones authored Jul 13, 2020

Demote headers which are clearly not kerneldoc, provide titles for
struct definition blocks, fix API slip (bitrot) misspellings and
provide some missing entries.

pinctrl: mediatek: pinctrl-mtk-common-v2: Mark 'mtk_default_register_base_names' as __maybe_unused · ea0b879b

Lee Jones authored Jul 13, 2020

Not all sourcefiles which end up including pinctrl-mtk-common-v2.h make use
of 'mtk_default_register_base_names' and there is nowhere we can place the
definition to void the need for __maybe_unused except its own headerfile,
which seems like overkill.  So instead we tell the compiler that it's okay
for it to be unused by some of the consumers.

pinctrl: aspeed: Improve debug output · aa639e44

We need to iterate over each pin in a group for a function and

muxing the relevant function's signal. With the current debug output it
is hard to track what register output is relevant to which operation, so
break up the actions in the debug output by providing some more context.

Modify omap_gpio_set_config() to handle pin config bias flags by calling
gpiochip_generic_config().

The pin group for the gpio line must have the corresponding pinconf
properties:

PIN_CONFIG_BIAS_PULL_UP requires "pinctrl-single,bias-pullup"
PIN_CONFIG_BIAS_PULL_DOWN requires "pinctrl-single,bias-pulldown"

This is necessary for pcs_pinconf_set() to find the requested bias

pinctrl: nsp: Set irq handler based on trig type · 94c70241

Mark Tomlinson authored Jul 03, 2020

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested. This is important for level triggered interrupts which need
to be masked during handling. Also, fix the interrupt acknowledge so
that it clears only one interrupt instead of all interrupts which are
currently active. Finally there is no need to clear the interrupt during
the interrupt handler, since the edge-triggered handler will do that for
us.

pinctrl: amd: Honor IRQ trigger type requested by the caller · 5f4962dd

Furquan Shaikh authored Jun 26, 2020

This change drops the override in `amd_gpio_irq_set_type()` that
ignores the IRQ trigger type settings from the caller. The device
driver (caller) is in a better position to identify the right trigger
type for the device based on the usage as well as the information
exposed by the BIOS. There are instances where the device driver might
want to configure the trigger type differently in different modes. An
example of this is gpio-keys driver which configures IRQ type as
trigger on both edges (to identify assert and deassert events) when in
S0 and reconfigures the trigger type using the information provided by
the BIOS when going into suspend to ensure that the wake happens on
the required edge.

This override in `amd_gpio_irq_set_type()` prevents the caller from
being able to reconfigure trigger type once it is set either based on
ACPI information or the type used by the first caller for IRQ on a
given GPIO line.

Without this change, pen-insert gpio key (used by garaged stylus on a
Chromebook) works fine in S0 (i.e. insert and eject events are
correctly identified), however, BIOS configuration for wake on only
pen eject i.e. only-rising edge or only-falling edge is not honored.

With this change, it was verified that pen-insert gpio key behavior is
correct in both S0 and for wakeup from S3.

pinctrl: ingenic: Properly detect GPIO direction when configured for IRQ · 84e7a946

Paul Cercueil authored Jun 22, 2020

The PAT1 register contains information about the IRQ type (edge/level)
for input GPIOs with IRQ enabled, and the direction for non-IRQ GPIOs.
So it makes sense to read it only if the GPIO has no interrupt
configured, otherwise input GPIOs configured for level IRQs are
misdetected as output GPIOs.

pinctrl: ingenic: Enhance support for IRQ_TYPE_EDGE_BOTH · 1c95348b

Paul Cercueil authored Jun 22, 2020

Ingenic SoCs don't natively support registering an interrupt for both
rising and falling edges. This has to be emulated in software.

Until now, this was emulated by switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING according to the level of
the GPIO. While this worked most of the time, when used with GPIOs that
need debouncing, some events would be lost. For instance, between the
time a falling-edge interrupt happens and the interrupt handler
configures the hardware for rising-edge, the level of the pin may have
already risen, and the rising-edge event is lost.

To address that issue, instead of switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING, we now switch back and
forth between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH. Since we
always switch in the interrupt handler, they actually permit to detect
level changes. In the example above, if the pin level rises before
switching the IRQ type from IRQ_TYPE_LEVEL_LOW to IRQ_TYPE_LEVEL_HIGH,
a new interrupt will raise as soon as the handler exits, and the
rising-edge event will be properly detected.

pinctrl: meson: fix drive strength register and bit calculation · f088ab6d

Hyeonki Hong authored Jun 18, 2020

If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.

The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.
