Adds a driver for a mini gamepad that communicates over i2c, the gamepad
has bidirectional thumb stick input and six buttons.
The gamepad chip utilizes the open framework from Adafruit called 'Seesaw'
to transmit the ADC data for the joystick and digital pin state for the
buttons. I have only implemented the functionality required to receive the
thumb stick and button state.
Steps in reading the gamepad state over i2c:
1. Reset the registers
2. Set the pin mode of the pins specified by the `BUTTON_MASK` to input
`BUTTON_MASK`: A bit-map for the six digital pins internally
connected to the joystick buttons.
3. Enable internal pullup resistors for the `BUTTON_MASK`
4. Bulk set the pin state HIGH for `BUTTON_MASK`
5. Poll the device for button and joystick state done by:
`seesaw_read_data(struct i2c_client *client, struct seesaw_data *data)`

The Linux kernel is notorious for misspelling X-Box, X-box, XBox or XBOX;
the official spelling is actually just Xbox. Plain and simple.
Tried to respect the existing notes but still following the style guide.
No functional changes intended. This only affects ancillary parts.

Since JOYSTICK_SENSEHAT selects MFD_SIMPLE_MFD_I2C and the latter
depends on HAS_IOMEM, and since 'select' does not follow any
dependency chains, JOYSTICK_SENSEHAT should also depend on HAS_IOMEM
to prevent a kconfig warning and a build error:
WARNING: unmet direct dependencies detected for MFD_SIMPLE_MFD_I2C

Pull UML updates from Richard Weinberger:
- Support for optimized routines based on the host CPU
- Support for PCI via virtio
- Various fixes
* tag 'for-linus-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml:
um: remove unneeded semicolon in um_arch.c
um: Remove the repeated declaration
um: fix error return code in winch_tramp()
um: fix error return code in slip_open()
um: Fix stack pointer alignment
um: implement flush_cache_vmap/flush_cache_vunmap
um: add a UML specific futex implementation
um: enable the use of optimized xor routines in UML
um: Add support for host CPU flags and alignment
um: allow not setting extra rpaths in the linux binary
um: virtio/pci: enable suspend/resume
um: add PCI over virtio emulation driver
um: irqs: allow invoking time-travel handler multiple times
um: time-travel/signals: fix ndelay() in interrupt
um: expose time-travel mode to userspace side
um: export signals_enabled directly
um: remove unused smp_sigio_handler() declaration
lib: add iomem emulation (logic_iomem)
um: allow disabling NO_IOMEM
Adjust the kconfig a little to allow disabling NO_IOMEM in UML. To
make an "allyesconfig" with CONFIG_NO_IOMEM=n build, adjust a few
Kconfig things elsewhere and add dummy asm/fb.h and asm/vga.h files.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Making module name conflicts a fatal error breaks sparc64 allmodconfig:
Error log:
error: the following would cause module name conflict:
drivers/char/adi.ko
drivers/input/joystick/adi.ko
Renaming one of the modules would solve the problem, but then cause other
problems because neither of them is automatically loaded and changing
the name is likely to break any setup that relies on manually loading
it by name.
As there is probably no sparc64 system with this kind of ancient joystick
attached, work around it by adding a Kconfig dependency that forbids
them from both being modules. It is still possible to build the joystick
driver if the sparc64 adi driver is built-in.

We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts psxpad-spi driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.

This patch adds support for the FlySky FS-iA6B RC receiver (serial IBUS).
It allows the usage of the FlySky FS-i6 and other AFHDS compliant remote
controls as a joystick input device.
To use it, a patch to inputattach which adds the FS-iA6B as a 115200 baud
serial device is required. I will upstream it after this patch is merged.
