thermal/drivers/rcar: Fix error checking in probe()
This code accidentally calls thermal_zone_device_enable() before checking
whether thermal_zone_device_register_with_trips() failed.  Move the call
until later to avoid an error pointer dereference of "priv->zone".

The driver works differently depending on if we are using OF thermal or
not.  We use thermal_add_hwmon_sysfs() if we are using OF thermal and
call thermal_zone_device_enable() if not.  We can share same error check
for if either of these fail.

Moving the thermal_zone_device_enable() call is a bit cleaner as well.
The original code used a three step process to cleanup:
1. Call thermal_zone_device_unregister() to cleanup.
2. Set priv->zone to an error pointer to preserve the error code.
3. Set priv->zone to NULL to avoid a second call to
   thermal_zone_device_unregister() in the rcar_thermal_remove()
   function.

Now we can just do a direct goto error_unregister and rcar_thermal_remove()
handles the cleanup properly.

ebf1d03dab iio: inkern: Use namespaced exports
Use namespaced exports for IIO consumer API functions.

This will make it easier to manage the IIO export surface. Consumer drivers
will only be provided access to a specific set of functions, thereby
restricting usage of internal IIO functions by other parts of the kernel.

This change cannot be split into several parts without breaking
bisectability, thus all of the affected drivers are modified at once.

0061030929 thermal: renesas: rzg3e: add support for RZ/T2H and RZ/N2H
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the
temperature calibration via SMC SIP and do not have a reset for the
TSU peripheral, and use different minimum and maximum temperature values
compared to the already supported RZ/G3E.

Although the calibration data is stored in an OTP memory, the OTP itself
is not memory-mapped, access to it is done through an OTP controller.

The OTP controller is only accessible from the secure world,
but the temperature calibration data stored in the OTP is exposed via
SMC.

Add support for retrieving the calibration data using arm_smcc_smc().

Add a compatible for RZ/T2H, RZ/N2H can use it as a fallback.

c33edd8f93 thermal: renesas: rzg3e: make calibration value retrieval per-chip
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the
temperature calibration data via SMC SIP calls.

To prepare for supporting these SoCs, do the following changes.

Rename rzg3e_thermal_parse_dt() to rzg3e_thermal_get_syscon_trim().

Move the syscon usage out of rzg3e_thermal_get_calibration() and into
rzg3e_thermal_get_syscon_trim() and remove single-use variables from the
private state.

Place a pointer to rzg3e_thermal_get_syscon_trim() into the
chip-specific struct, and use it in the probe function to retrieve the
calibration values.

Now that syscon usage has been moved out of
rzg3e_thermal_get_calibration(), remove it and inline the calibration
validation into the probe function.

Also, reuse the TSU_CODE_MAX macro to mask the calibration values, as
GEMASK(11, 0) and 0xFFF are equivalent, and replace the hardcoded 0xFFF
with TSU_CODE_MAX in the calibration validation.

S4 was added first so it was assumed to be the blueprint for R-Car Gen4.
It turned out now, that S4 is a special mix between Gen3 and Gen4. V4H
and V4M are the similar ones as confirmed by HW engineers.

So, rename the S4 entry to be specific instead of generic. Rename the
V4H entry to be the new generic one, so V4M will use it as well now.

84fd9e4a6b thermal/drivers/rcar_gen3: Add support for per-SoC default trim values
The Working Sample R-Car SoCs may not yet have thermal sensor trimming
values programmed into fuses, those fuses are blank instead. For such
SoCs, the driver includes fallback trimming values. Those values are
currently applied to all SoCs which use this driver.

Introduce support for per-SoC fallback trimming values in preparation
for SoCs which do not use these current trimming values. No functional
change is intended here.

992e2ed0ab thermal: Constify struct thermal_zone_device_ops
'struct thermal_zone_device_ops' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  28116	   5168	    128	  33412	   8284	drivers/thermal/armada_thermal.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  28244	   5040	    128	  33412	   8284	drivers/thermal/armada_thermal.o

bccdbba51a thermal: rcar_gen3: Reuse logic to read fuses on Gen3 and Gen4
The hardware calibration is fused on some, but not all, Gen3 and Gen4
boards. The calibrations values are the same on both generations but
located at different register offsets.

Instead of having duplicated logic to read the and store the values
create structure to hold the register parameters and have a common
function do the reading.

dd64594ca2 thermal: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/thermal to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way make a few whitespace changes to make indention consistent.

79f194dd54 thermal: trip: Get rid of thermal_zone_get_num_trips()
The only existing caller of thermal_zone_get_num_trips(), which is
rcar_gen3_thermal_probe(), uses this function to put the number of
trip points into a kernel log message, but this information is also
available from the thermal sysfs interface.

For this reason, remove the thermal_zone_get_num_trips() call from
rcar_gen3_thermal_probe() and drop the former altogether.
