thermal_of_trips_init()
Obtain the device node reference and allocate memory with
scoped/cleanup.h to reduce error handling and make the code a bit
simpler.
The code is not equivalent in one minor aspect: outgoing parameter
"*ntrips" will not be zeroed on errors of memory allocation. This
difference is not important, because code was already not zeroing it in
case of earlier errors and the only caller does not rely on ntrips being
0 in case of errors.

Commit 0dc23567c206 ("thermal: core: Move lists of thermal instances
to trip descriptors") overlooked the case in which the Power Allocator
governor attempts to bind to a tripless thermal zone and params->trip_max
is NULL in check_power_actors().
No power actors can be found in that case, so check_power_actors() needs
to be made return 0 then to restore its previous behavior.

`atmel_qspi_reg_name()` is used for pretty-printing register offsets
for verbose logging of register accesses. However, due to a typo
(likely a copy-paste error), QSPI_RD's offset prints as "MR", the
name of the previous register. Fix this typo.

During initialization, the AF driver resets all blocks. The RPM (MAC)
block and NIX block operate on a credit-based model. When the NIX block
resets during active traffic flow, it doesn't release credits to the RPM
block. This causes the RPM FIFO to overflow, leading to receive traffic
struck.
To address this issue, the patch introduces the following changes:
1. Stop receiving traffic at the MAC level during AF driver
initialization.
2. Perform an X2P reset (prevents RXFIFO of all LMACS from pushing data)
3. Reset the NIX block.
4. Clear the X2P reset and re-enable receiving traffic.

Low network performance is observed even on RPMs with larger
FIFO lengths.
The cn10kb silicon has three RPM blocks with the following
FIFO sizes:
--------------------
| RPM0 | 256KB |
| RPM1 | 256KB |
| RPM2 | 128KB |
--------------------
The current design stores the FIFO length in a common structure for all
RPMs (mac_ops). As a result, the FIFO length of the last RPM is applied
to all RPMs, leading to reduced network performance.
This patch resolved the problem by storing the fifo length in per MAC
structure (cgx).

On DWMAC3 and later, there's a RX Watchdog interrupt that's used for
interrupt coalescing. It's known to be buggy on some platforms, and
dwmac-socfpga appears to be one of them. Changing the interrupt
coalescing from ethtool doesn't appear to have any effect here.
Without disabling RIWT (Received Interrupt Watchdog Timer, I
believe...), we observe latencies while receiving traffic that amount to
around ~0.4ms. This was discovered with NTP but can be easily reproduced
with a simple ping. Without this patch :

If the clock pep->clk was not enabled in pxa168_eth_probe,
it should not be disabled in any path.
Conversely, if it was enabled in pxa168_eth_probe, it must be disabled
in all error paths to ensure proper cleanup.
Use the devm_clk_get_enabled helper function to ensure proper call balance

The undervoltage flags reported by the RTC are useful to know if the
time and date are reliable after a reboot. Although the threshold VLOW1
indicates that the thermometer has been shutdown and time compensation
is off, it doesn't mean that the temperature readout is currently
impossible.
As the system is running, the RTC voltage is now fully established and
we can read the temperature.

This RTC has special 32bit registers which return multiple of the same
8bit registers at once. Use these to minimize register access. Also, do
the to/from BCD conversions right away, so 'tm' always contains values
as described in time.h.

The week register simply counts from 0 to 6 where the numbers do not
even represent a specific weekday. So we can adopt 'tm_wday' numbering
of the RTC core without converting it.
