This patch adds the support for thermal sensor on the Hi3660 SoC.
Hi3660 tsensor support alarm in alarm threshold, it also has a configurable
hysteresis interval, interrupt will be triggered when temperature rise above
the alarm threshold or fall below the hysteresis threshold.

For platform compatibility, add the tsensor ops to a thermal data
structure. Each platform has its own probe function to register proper
tsensor ops function to the pointer, platform related resource request
are also implemented in the platform probe function.

As the next patches will provide support for the hikey3660's sensor,
several functions with the same purpose but for different platforms will
be introduced.
In order to make a clear distinction between them, let's prefix the
function names with the platform name.
This patch has no functional changes, only name changes.

The mutex is used to protect against writes in the configuration register.
That happens at probe time, with no possible race yet.
Then when the module is unloaded and at suspend/resume.
When the module is unloaded, it is an userspace operation, thus via a process.
Suspending the system goes through the freezer to suspend all the tasks
synchronously before continuing. So it is not possible to hit the suspend ops
in this driver while we are unloading it.
The resume is the same situation than the probe.
In other words, even if there are several places where we write the
configuration register, there is no situation where we can write it at the same
time, so far as I can judge

The presence of the thermal data pointer in the sensor structure has the unique
purpose of accessing the thermal data in the interrupt handler.
The sensor pointer is passed when registering the interrupt handler, replace the

The sensor is all setup, bind, resetted, acked, etc... every single second.
That was the way to workaround a problem with the interrupt bouncing again and
again.
With the following changes, we fix all in one:
- Do the setup, one time, at probe time
- Add the IRQF_ONESHOT, ack the interrupt in the threaded handler
- Remove the interrupt handler
- Set the correct value for the LAG register
- Remove all the irq_enabled stuff in the code as the interruption
handling is fixed
- Remove the 3ms delay
- Reorder the initialization routine to be in the right order
It ends up to a nicer code and more efficient, the 3-5ms delay is removed from
the get_temp() path.

The TEMP0_CFG configuration register contains different field to set up the
temperature controller. However in the code, nothing prevents a setup to
overwrite the previous one: eg. writing the hdak value overwrites the sensor
selection, the sensor selection overwrites the hdak value.
In order to prevent such thing, use a regmap-like mechanism by reading the
value before, set the corresponding bits and write the result.

By essence, the tsensor does not really support multiple sensor at the same
time. It allows to set a sensor and use it to get the temperature, another
sensor could be switched but with a delay of 3-5ms. It is difficult to read
simultaneously several sensors without a big delay.
Today, just one sensor is used, it is not necessary to deal with multiple
sensors in the code. Remove them and if it is needed in the future add them
on top of a code which will be clean up in the meantime.

commit 0a5191efe06b5103909206e4fbcff81d30283f8e upstream.
Since commit aef9a7bd9b ("serial/uart/8250: Add tunable RX interrupt
trigger I/F of FIFO buffers"), the port's default FCR value isn't used
in serial8250_do_set_termios anymore, but copied over once in
serial8250_config_port and then modified as needed.
Unfortunately, serial8250_config_port will never be called if the port
is shared between kernel and userspace, and the port's flag doesn't have
UPF_BOOT_AUTOCONF, which would trigger a serial8250_config_port as well.
This causes garbled output from userspace:
[ 5.220000] random: procd urandom read with 49 bits of entropy available
ers
[kee
Fix this by forcing it to be configured on boot, resulting in the
expected output:
[ 5.250000] random: procd urandom read with 50 bits of entropy available
