Inspried from
commit e8688fe8df ("clk: imx8mn: Define gates for pll1/2 fixed dividers")
On imx8mp there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.

Same to i.MX8MN/i.MX8MM, pll BYPASS bit should be kept inside pll
driver for glitchless freq setting following spec. If exposing the
bit, that means pll driver and clk driver has two paths to touch
this bit, which is wrong.
So use EXT_BYPASS bit here.

We found out that after phy up, the hardware reports another oob interrupt
but did not follow a phy up interrupt:
oob ready -> phy up -> DEV found -> oob read -> wait phy up -> timeout
We run link reset when wait phy up timeout, and it send a normal disk into
reset processing. So we made some circumvention action in the code, so that
this abnormal oob interrupt will not start the timer to wait for phy up.

Export through sysfs as a scsi_disk attribute the zoned capabilities of a
disk ("zoned_cap" attribute file). This new attribute indicates in human
readable form (i.e. a string) the zoned block capabilities implemented by
the disk as found in the ZONED field of the disk block device
characteristics VPD page. The possible values are:
- "none": ZONED=00b (not reported), regular disk
- "host-aware": ZONED=01b, host-aware ZBC disk
- "drive-managed": ZONED=10b, drive-managed ZBC disk (regular disk
interface)
For completeness, also add the following value which is detected using the
device type rather than the ZONED field:
- "host-managed": device type = 0x14 (TYPE_ZBC), host-managed ZBC disk
This new sysfs attribute is purely informational and complementary to the
"zoned" device request queue sysfs attribute as it allows applications and
user daemons (e.g. udev) to easily differentiate regular disks from
drive-managed SMR disks without the need for direct access tools such as
provided by sg3utils.

Elsewhere in the file, the function trace_kprobe_has_same_kprobe uses
a trace_probe_event.probes object as the second argument of
list_for_each_entry, ie as a list head, while the list_for_each_entry
iterates over the list fields of the trace_probe structures, making
them the list elements. So, exchange the arguments on the list_add
call to put the list head in the second argument.
Since both list_head structures were just initialized, this problem
did not cause any loss of information.

When an anomaly is detected in the function call modification
code, ftrace_bug() is called to disable function tracing as well
as give some warn and information that may help debug the problem.
But currently, we call FTRACE_WARN_ON_ONCE() first in ftrace_bug(),
so when panic_on_warn is set, we can't see the debugging information
here. Call FTRACE_WARN_ON_ONCE() at the end of ftrace_bug() to ensure
that the debugging information is displayed first.

The ufshcd_wait_for_register() function either sleeps or spins until the
specified register has reached the desired value. Busy-waiting is not only
considered a bad practice but also has a bad impact on energy
consumption. Always sleep instead of spinning by making sure that all
ufshcd_wait_for_register() calls happen from a context where it is allowed
to sleep. The only function call that has to be moved is the
ufshcd_hba_stop() call in ufshcd_host_reset_and_restore().

The current codebase makes use of one-element arrays in the following
form:
struct something {
int length;
u8 data[1];
};
struct something *instance;
instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL);
instance->length = size;
memcpy(instance->data, source, size);
but the preferred mechanism to declare variable-length types such as
these ones is a flexible array member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on. So, replace
the one-element array with a flexible-array member.
Also, make use of the new struct_size() helper to properly calculate the
size of struct siw_pbl.
This issue was found with the help of Coccinelle and, audited and fixed
_manually_.
