imx8m_blk_ctrl_driver_init may hang the system because the BUS clk is

Add back gate ops, but with disable doing nothing, then the CCM ROOT

The clk_set_parent for "enet1_ref_sel" and "enet2_ref_sel" are
incorrect, therefore the original requirements to have "enet_clk_ref" as
output sourced by iMX ENET PLL as a default config is not met.
Only "enet[1,2]_ref_125m" "enet[1,2]_ref_pad" are possible parents for
"enet1_ref_sel" and "enet2_ref_sel".
This was observed as a regression using a custom device tree which was
expecting this default config.
This can be fixed at the device tree level but having a default config
matching the original behavior (before refclock mux) will avoid breaking
existing configs.

QCS8550 is derived from SM8550. The difference between SM8550 and
QCS8550 is QCS8550 doesn't have modem RF system. QCS8550 is mainly used
in IoT products.
QCS8550 firmware has different memory map compared to SM8550.
The memory map will be runtime added through bootloader.
There are 3 types of reserved memory regions here:
1. Firmware related regions which aren't shared with kernel.
The device tree source in kernel doesn't need to have node to indicate
the firmware related reserved information. Bootloader converys the
information by updating devicetree at runtime.
This will be described as: UEFI saves the physical address of the
UEFI System Table to dts file's chosen node. Kernel read this table and
add reserved memory regions to efi config table. Current reserved memory
region may have reserved region which was not yet used, release note of
the firmware have such kind of information.
2. Firmware related memory regions which are shared with Kernel
The device tree source in the kernel needs to include nodes that
indicate fimware-related shared information. A label name is suggested
because this type of shared information needs to be referenced by
specific drivers for handling purposes.
Unlike previous platforms, QCS8550 boots using EFI and describes
most reserved regions in the ESRT memory map. As a result, reserved
memory regions which aren't relevant to the kernel(like the hypervisor
region) don't need to be described in DT.
3. Remoteproc regions.
Remoteproc regions will be reserved and then assigned to subsystem
firmware later.
Here is a reserved memory map for this platform:
0x80000000 +-------------------+
| |
| Firmware Related |

0x8a800000 +-------------------+

Currently the keyboard backlight is described in the common
sc7180-trogdor dtsi as an led node below a pwmleds node, and the led
node is set to disabled. Only the boards that have a keyboard backlight
enable it.
However, since the parent pwmleds node is still enabled everywhere, even
on boards that don't have keyboard backlight it is probed and fails,
resulting in an error:
leds_pwm pwmleds: probe with driver leds_pwm failed with error -22
as well as a failure in the DT kselftest:
not ok 45 /pwmleds
Fix this by controlling the status of the parent pwmleds node instead of
the child led, based on the presence of keyboard backlight. This is what
is done on sc7280 already.
While at it add a missing blank line before the child node to follow the
coding style.

This patch moves "post_socket_cb" and "noconnect" into connect_to_addr(),
then connect_to_fd_opts() can be implemented by getsockname() and
connect_to_addr(). This change makes connect_to_* interfaces more unified.

The opts.{type, noconnect} is at least a bit non intuitive or unnecessary.
The only use case now is in test_bpf_ip_check_defrag_ok which ends up
bypassing most (or at least some) of the connect_to_fd_opts() logic. It's
much better that test should have its own connect_to_fd_opts() instead.
This patch adds a new "type" parameter for connect_to_fd_opts(), then
opts->type and getsockopt(SO_TYPE) can be replaced by "type" parameter in
it.
In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass
it to connect_to_fd_opts().
In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to
connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW"
and "SOCK_DGRAM" are passed to it.
With these changes, the strcut member "type" of network_helper_opts can be
dropped now.

If the `amd-pstate` driver is not loaded automatically by default,
it is because the kernel command line parameter has not been added.
To resolve this issue, it is necessary to call the `amd_pstate_set_driver()`
function to enable the desired mode (passive/active/guided) before registering
the driver instance.
This ensures that the driver is loaded correctly without relying on the kernel
command line parameter.
When there is no parameter added to command line, Kernel config will
provide the default mode to load.
Meanwhile, user can add driver mode in command line which will override
the kernel config default option.

The amd-pstate-epp driver has been implemented and resolves the
performance drop issue seen in passive mode for shared memory type
CPPC systems. Users who enable the active mode driver will not
experience a performance drop compared to the passive mode driver.
Therefore, the EPP driver should be loaded by default for shared
memory type CPPC system to get better performance.

replace the usage of the deprecated boot_cpu_has() function with
the modern cpu_feature_enabled() function. The switch to cpu_feature_enabled()
ensures compatibility with the latest CPU feature detection mechanisms and
improves code maintainability.
