This patch adds the device tree support for FSL LS2085A SoC
based on ARMv8 architecture.
Following levels of DTSI/DTS files have been created for the
LS2085A SoC family:
- fsl-ls2085a.dtsi:
DTS-Include file for FSL LS2085A SoC.
- fsl-ls2085a-simu.dts:
DTS file for FSL LS2085a software simulator model.
In addition, this patch adds build support for FSL's LS2085A
simulator model in arm64 dts Makefile.

On st21nfca, the mechanism to enable a secure element needs to add 2
properties in order manage the SWP line correctly.
Document ese-present and uicc-present properties.

st21nfca has 1 physical SWP line and can support up to 2 secure elements
(UICC & eSE) thanks to an external switch managed with a gpio.
The platform integrator needs to specify thanks to 2 initialization
properties, uicc-present and ese-present, if it is suppose to have uicc
and/or ese. Of course if the platform does not have an external switch,
only one kind of secure element can be supported. Those parameters are
under platform integrator responsibilities.
During initialization, the white_list will be set according to those
parameters.
The discovery_se function will assume a secure element is physically
present according to uicc-present and ese-present values and will add it
to the secure element list. On ese activation, the atr is retrieved to
calculate a command exchange timeout based on the first atr(TB) value.
The se_io will allow to transfer data over SWP. 2 kind of events may appear
after a data is sent over:
- ST21NFCA_EVT_TRANSMIT_DATA when receiving an apdu answer
- ST21NFCA_EVT_WTX_REQUEST when the secure element needs more time than
expected to compute a command. If this timeout expired, a first recovery
tentative consist to send a simple software reset proprietary command.
If this tentative still fail, a second recovery tentative consist to send
a hardware reset proprietary command.
This function is only relevant for eSE like secure element.
This patch also change the way a pipe is referenced. There can be
different pipe connected to the same gate with different host destination
(ex: CONNECTIVITY). In order to keep host information every pipe are
reference with a tuple (gate, host). In order to reduce changes, we are
keeping unchanged the way a gate is addressed on the Terminal Host.
However, this is working because we consider the apdu reader gate is only
present on the eSE slot also the connectivity gate cannot give a reliable
value; it will give the latest stored pipe value.

As there can be several pipes connected to the same gate, we need

When ktest runs the console program as a child process, the parent and
child share the same tty for stdin and stderr. This is problematic when
using a libvirt target. The "virsh console" program makes a lot of
changes to the tty settings, making ktest's output hard to read
(carriage returns don't work). After ktest exits, the terminal is
unusable (CRs broken, stdin isn't echoed).
I think the best way to fix this issue would be to create a
pseudoterminal (pty pair) so the child process would have a dedicated
tty, and then use pipes to connect the two ttys. I'm not sure if that's
overkill, but it's far beyond my current Perl abilities.
This patch is a much easier way to (partially) fix this issue. It saves
the tty settings before opening the console and restores them after
closing it. There are still a few places where ktest prints mangled
output while the console is open, but the output is much more legible
overall, and the terminal works just fine after ktest exits.

Several pipes may point to the same CLF gate, so getting the gate ID
as an input is not enough.
For example dual secure element may have 2 pipes (1 for uicc and
1 for eSE) pointing to the connectivity gate.
As resolving gate and host IDs can be done from a pipe, we now pass
the pipe ID to the event received handler.

Some of the clks can be registered & unregistered before the clk related debugfs
entries are initialized at late_initcall. In the unregister path checking for only
dentry before clk_debug_init() would lead dangling pointers in the debug clk list,
because the list is already populated in register path and the clk pointer freed in
unregister path.
The side effect of not removing it from the list is either a null pointer
dereference or if lucky to boot the system, the number of clk entries in
debugfs disappear.
We could add more checks like if (inited && !clk->dentry) but just removing
the check for dentry made more sense as debugfs_remove_recursive() seems to be
safe with null pointers. This will ensure that the unregistering clk would be
removed from the debug list in all the code paths.
Without this patch kernel would crash with log:
