It turns out that one specific hardware has two direction
registers: one to set a GPIO line as input and another one
to set a GPIO line as output. So in theory a line can be
configured as input and output at the same time.
Make the MMIO GPIO helper deal with this: store both
registers in the state container, use both in the generic
code if present. Synchronize the input register to the
output register when we register a GPIO chip, with the
output settings taking precedence.
Keep the helper variable to detect inverted direction
semantics (only direction in register) but augment the
code to be more straight-forward for the generic case
when setting the registers.
Fix some flunky with unreadable direction registers at
the same time as we're touching this code.

gpio fixes for v5.1-rc3
- fix for a potential NULL-pointer dereference in the aspeed driver
- revert of the commit using the new gpio_set_config() when setting
debaunce and transitory state config as it caused a regression in
the aspeed driver
- two fixes for gpio-mockup for debugfs problems introduced in the

If the call to of_gpiochip_scan_gpios() in of_gpiochip_add() fails, no
error handling is performed. This lead to the need of callers to call
of_gpiochip_remove() on failure, which causes "BAD of_node_put() on ..."
if the failure happened before the call to of_node_get().
Fix this by adding proper error handling.
Note that calling gpiochip_remove_pin_ranges() multiple times causes no
harm: subsequent calls are a no-op.

SPI GPIO device has more than just "cs-gpio" property in its node and
would request those GPIOs as a part of its initialization. To avoid
applying CS-specific quirk to all of them add a check to make sure
that propname is "cs-gpios".

We are currently assuming all GPIOs are non-wakeup capable GPIOs as we
not configuring the bank->non_wakeup_gpios like we used to earlier with
platform_data.
Let's add omap_gpio_is_off_wakeup_capable() to make the handling clearer
while considering that later patches may want to configure SoC specific
bank->non_wakeup_gpios for the GPIOs in wakeup domain.

The bank->workaround_enabled should be for omap24xx erratum 1.101 but is not
needed any longer as erratum 1.101 handling only needs to happen based on
!bank->loses_context with patch "gpio: omap: Limit errata 1.101 handling to
wkup domain gpios only".
Further Grygorii Strashko <[email protected]> points out that we are
now tagging all edge GPIOs as non-wakeup GPIOs and rely on original erratum
1.101 handling for scacnning for edge interrupts that have triggered during
idle.
Also the TI Android kernel tree has an earlier commit "GPIO: OMAP: Always
scan gpios during runtime resume" by Tero Kristo <[email protected]> saying:
"This allows the driver to generate interrupts for GPIOs that can't
wakeup but have changed state during runtime suspend. We cannot
depend on the decision based on no need to restore, as the system
state might change and pending events could gather up."
So let's remove bank->workaround_enabled and always scan for triggered edge
interrupts on resume. We do that based on bank->enabled_non_wakeup_gpios.

We need to only apply errata 1.101 handling to clear non-wakeup edge gpios
for idle to the gpio bank(s) in the wkup domain to prevent spurious wake-up
events.
And we must restore what we did after idle manually as the gpio bank in
wkup domain is not restored otherwise.
Let's keep bank->saved_datain register reading separate, that's not related
to the 1.101 errata and is used separately on restore.

The debugfs read callback must advance ppos or users using read() on
the file descriptor will never get the EOL. This wasn't spotted before
as I was using busybox cat for testing which uses sendfile() internally

We only hit unregister_allocated_timer() if the argument to
aspeed_gpio_set_config() is 0, but we can't be calling through
gpiod_set_debounce() from gpio_keys_probe() unless the gpio-keys button has a
non-zero debounce interval.
Commit 6581eaf0e890 ("gpio: use new gpio_set_config() helper in more places")
spreads the use of gpio_set_config() to the debounce and transitory
state configuration paths. The implementation of gpio_set_config() is:
> static int gpio_set_config(struct gpio_chip *gc, unsigned offset,
> enum pin_config_param mode)
> {
> unsigned long config = { PIN_CONF_PACKED(mode, 0) };
>
> return gc->set_config ? gc->set_config(gc, offset, config) : -ENOTSUPP;
> }
Here it packs its own config value with a fixed argument of 0; this is
incorrect behaviour for implementing the debounce and transitory functions, and
the debounce and transitory gpio_set_config() call-sites now have an undetected
type mismatch as they both already pack their own config parameter (i.e. what
gets passed is not an `enum pin_config_param`). Indeed this can be seen in the
small diff for 6581eaf0e890:

Revert commit 6581eaf0e890 ("gpio: use new gpio_set_config() helper in
more places") to restore correct behaviour for gpiod_set_debounce() and
gpiod_set_transitory().
