Input: snvs_pwrkey - fix SNVS_HPVIDR1 register address

2022-10-05T08:39:37+00:00

commit e62563db857f81d75c5726a35bc0180bed6d1540 upstream.

Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1
(chapters 57.9 and 6.4.5 respectively).

Without this, trying to read the revision number results in 0 on
all revisions, causing the i.MX6 quirk to apply on all platforms,
which in turn causes the driver to synthesise power button release
events instead of passing the real one as they happen even on
platforms like i.MX8 where that's not wanted.

Fixes: 1a26c920717a ("Input: snvs_pwrkey - send key events for i.MX6 S, DL and Q")

Input: gpio-keys - cancel delayed work only in case of GPIO

2022-06-09T08:22:43+00:00

[ Upstream commit cee409bbba0d1bd3fb73064fb480ff365f453b5d ]

gpio_keys module can either accept gpios or interrupts. The module
initializes delayed work in case of gpios only and is only used if
debounce timer is not used, so make sure cancel_delayed_work_sync()
is called only when its gpio-backed and debounce_use_hrtimer is false.

This fixes the issue seen below when the gpio_keys module is unloaded and
an interrupt pin is used instead of GPIO:

Input: omap4-keypad - fix pm_runtime_get_sync() error checking

2022-04-27T12:38:58+00:00

[ Upstream commit 81022a170462d38ea10612cb67e8e2c529d58abe ]

If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.

Input: samsung-keypad - properly state IOMEM dependency

commit ba115adf61b36b8c167126425a62b0efc23f72c0 upstream.

Make the samsung-keypad driver explicitly depend on CONFIG_HAS_IOMEM, as it
calls devm_ioremap(). This prevents compile errors in some configs (e.g,
allyesconfig/randconfig under UML):

  Input: xpad - add support for another USB ID of Nacon GC-100
  Input: resistive-adc-touch - fix division by zero error on z1 == 0

Input: snvs_pwrkey - add clk handling

2021-10-16T05:11:01+00:00

On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
associated clock. Accessing the registers requires that this clock is
enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
having the clock enabled results in a complete hang of the machine.
(This usually only happens if snvs_pwrkey is built as a module and the
rtc-snvs driver isn't already bound because at bootup the required clk
is on and only gets disabled when the clk framework disables unused clks
late during boot.)

This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add
snvs clock to pwrkey").

Input: adc-keys - drop bogus __refdata annotation

2021-09-04T06:49:58+00:00

As the ADC ladder input driver does not have any code or data located in
initmem, there is no need to annotate the adc_keys_driver structure with
__refdata.  Drop the annotation, to avoid suppressing future section
warnings.
