CTRLMMR_MCU_SPI1_CTRL register controls if MCU_SPI1 is directly
connected to SPI3 in the MAIN Domain (default) or if MCU_SPI1
and SPI3 are independently pinned out. By default, the field
SPI1_LINKDIS (Bit 0) is set to 0h. In order to disable the direct
connection, the SPI1_LINKDIS (Bit 0) needs to be set to 1h. Model
this functionality as a "reg-mux" device and based on the idle-state
property, enable/disable the connection bewtween MCU_SPI1 and MAIN_SPI3.
The register field description has been referred from J7200 TRM [1]
(Table 5-517. CTRLMMR_MCU_SPI1_CTRL Register Field Descriptions).

ICSSG has 7 available clocks per instance. Add all the cloks to ICSSG
nodes. ICSSG currently uses ICSSG_ICLK (clk id 20) which operates at
250MHz. Switch ICSSG clock to ICSSG_CORE clock (clk id 0) which operates at
333MHz.
ICSSG_CORE clock will help get the most out of ICSSG as more cycles are
needed to fully support all ICSSG features.
This commit also changes assigned-clock-parents of coreclk-mux to
ICSSG_CORE clock from ICSSG_ICLK.
Performance update in dual mac mode
With ICSSG_CORE Clk @ 333MHz
Tx throughput - 934 Mbps
Rx throughput - 914 Mbps,
With ICSSG_ICLK clk @ 250MHz,

After the SoC has entered the Deep Sleep mode, USB1 can be used to wakeup
the SoC based on USB events triggered by USB devices. This requires that
the pin corresponding to the Type-A connector remains pulled up even after
the SoC has entered the Deep Sleep mode. Hence, enable Deep Sleep pullup /
pulldown selection for the USB1_DRVVBUS pin and set its Deep Sleep state to

Pull i2c component probing support from Wolfram Sang:
"Add OF component probing.
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular
device can be detected by some firmware provided identifier, other
times that information is not available, and the kernel has to try to
probe each device.
Instead of a delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component probe function. For a
given class of devices on the same I2C bus, it will go through all of
them, doing a simple I2C read transfer and see which one of them
responds. It will then enable the device that responds"

These are functions that are used by trace_printk() that allows to

the expensive processing of converting numbers to ASCII. Then on
output, at a much later time, the ring buffer is read and the string
processing occurs then. The bprintf() was added for consistency but

The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.
So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination. But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.
It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).
Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer). Otherwise it returns the string length of the
result.
However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.
In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.
Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.
[ Note that "final byte is NUL" here is literally about the final byte
in the destination array, not the terminating NUL at the end of the
string itself. There is no attempt to try to make concurrent reads and
writes give any kind of consistent string length or contents, but we
do want to guarantee that there is always at least that final
terminating NUL character at the end of the destination array if it
existed before ]
This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).
So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

Pull sh updates from John Paul Adrian Glaubitz:
"Two small fixes.
The first one by Huacai Chen addresses a runtime warning when
CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected
which occurs because the cpuinfo code on sh incorrectly uses NR_CPUS
when iterating CPUs instead of the runtime limit nr_cpu_ids.
A second fix by Dan Carpenter fixes a use-after-free bug in
register_intc_controller() which occurred as a result of improper
error handling in the interrupt controller driver code when
registering an interrupt controller during plat_irq_setup() on sh"

assorted minor bug fixes
assorted platform specific tweaks
initial RAPL PSYS (SysWatt) support

Introduce the counter as a part of global, platform counters structure.
We open the counter for only one cpu, but otherwise treat it as an
ordinary RAPL counter, allowing for grouped perf read.
The counter is disabled by default, because it's interpretation may
require additional, platform specific information, making it unsuitable
for general use.

Add '+' to optstring when early scanning for --no-msr and --no-perf.
It causes option processing to stop as soon as a nonoption argument is
encountered, effectively skipping child's arguments.

Force the --no-perf early to prevent using it as a source. User asks for
raw values, but perf returns them relative to the opening of the file
descriptor.

On some machines, the graphics device is enumerated as
/sys/class/drm/card1 instead of /sys/class/drm/card0. The current
implementation does not handle this scenario, resulting in the loss of
graphics C6 residency and frequency information.
Add support for /sys/class/drm/card1, ensuring that turbostat can
retrieve and display the graphics columns for these platforms.

Snapshots of the graphics sysfs knobs are taken based on file
descriptors. To optimize this process, open the files and cache the file
descriptors during the graphics probe phase. As a result, the previously
cached pathnames become redundant and are removed.
This change aims to streamline the code without altering its functionality.
No functional change intended.

Currently, there is an inconsistency in how graphics sysfs knobs are
accessed: graphics residency sysfs knobs are opened and closed for each
read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds
unnecessary code complexity.
Consolidate the access method by opening the sysfs files once and
reusing the file pointers for subsequent accesses. This approach
simplifies the code and ensures a consistent method for accessing
graphics sysfs knobs.

The graphics sysfs knobs are read-only, making the use of fflush()

In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.
To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.
Converts `adl_features` and `lnl_features` to follow this new scheme.
No functional change.
