The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".
Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.
Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.
So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap
attribute. The attribute would be a space separated ordered list of
row/column codes for the keys in the function row, in a left-to-right
order.
The attribute will only be present when the device has a custom design
for the top-row keys.

For some reason, when the system is under heavy CPU load, the read
following the write sometimes occurs unusually quickly, resulting in
the read data not being quite ready and hence a bad packet getting read.
Adding another delay after reading the status message appears to fix
this.

The response to a command may never arrive or it may be corrupted (and
hence dropped) for some reason. While exceedingly rare, when it did
happen it blocked all further commands. One way to fix this was to
do a suspend/resume. However, recovering automatically seems like a
nicer option. Hence this puts a time limit (1 sec) on how long we're
willing to wait for a response, after which we assume it got lost.

The driver core ignores the return value of struct bus_type::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct locomo_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

We are still missing handling for errata i689 related issues for the
case where we never see a key up interrupt for the last pressed key.
To fix the issue, we must scan the key state again after the keyboard
controller has idled to check if a key up event was missed. This is
described in the omap4 silicon errata documentation for Errata ID i689
"1.32 Keyboard Key Up Event Can Be Missed":
"When a key is released for a time shorter than the debounce time,
in-between 2 key press (KP1 and KP2), the keyboard state machine will go
to idle mode and will never detect the key release (after KP1, and also
after KP2), and thus will never generate a new IRQ indicating the key
release."
We can use PM runtime autosuspend features to check the keyboard state
after it enters idle.

Because of errata i689 the keyboard can idle with state where no key
up interrupts are seen until after the next key press.
This means we need to first check for any lost key up events before
scanning for new down events.
For example, rapidly pressing shift-shift-j can sometimes produce a J
instead of j. Let's fix the issue by scanning the keyboard in two
phases. First we scan for any key up events that we may have missed,
and then we scan for key down events.
Let's also simplify things with for_each_set_bit() as suggested by
Dmitry Torokhov <dmitry.torokhov@gmail.com>.

In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

The Samsung touchkey controllers are often used with external pull-up

a regulator to bring the lines into usable state. Otherwise, this might

In omap4_keypad_probe, the patch fix several bugs.
1) pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak.
2) In err_unmap, forget to disable runtime of device,
pm_runtime_enable will increase power disable depth. Thus a
pairing decrement is needed on the error handling path to keep
it balanced.
3) In err_pm_disable, it will call pm_runtime_put_sync twice not
one time.
To fix this we factor out code reading revision and disabling touchpad, and
drop PM reference once we are done talking to the device.

platform_get_irq() returns -ERRNO on error. In such case casting to
unsigned and comparing to 0 would pass the check.

-ENOTSUPP is not a SUSV4 error code and should not be used. Use
-ENOPROTOOPT instead to report EC_RES_INVALID_VERSION responses
from the EC. This matches match the NFS response for unsupported
protocol versions.

This converts all the existing DECLARE_TASKLET() (and ...DISABLED)
macros with DECLARE_TASKLET_OLD() in preparation for refactoring the
tasklet callback type. All existing DECLARE_TASKLET() users had a "0"
data argument, it has been removed here as well.
