Default parent clock for the PWM on Tegra is a 32kHz clock and

Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by
updating the parent clock for the PWM to be the PLL_P.

[BUG]
There is a bug report that btrfs driver caused hang during file read:
This breaks btrfs on the HiFive Unmatched.
=> pci enum
PCIE-0: Link up (Gen1-x8, Bus0)
=> nvme scan
=> load nvme 0:2 0x8c000000 /boot/dtb/sifive/hifive-unmatched-a00.dtb
[hangs]
[CAUSE]
The reporter provided some debug output:
read_extent_data: cur=615817216, orig_len=16384, cur_len=16384
read_extent_data: btrfs_map_block: cur_len=479944704; ret=0
read_extent_data: ret=0
read_extent_data: cur=615833600, orig_len=4096, cur_len=4096
read_extent_data: btrfs_map_block: cur_len=479928320; ret=0
Note the second and the last line, the @cur_len is 450+MiB, which is
almost a chunk size.
And inside __btrfs_map_block(), we limits the returned value to stripe
length, but that's depending on the chunk type:
if (map->type & (BTRFS_BLOCK_GROUP_RAID0 | BTRFS_BLOCK_GROUP_RAID1 |
BTRFS_BLOCK_GROUP_RAID1C3 | BTRFS_BLOCK_GROUP_RAID1C4 |
BTRFS_BLOCK_GROUP_RAID5 | BTRFS_BLOCK_GROUP_RAID6 |
BTRFS_BLOCK_GROUP_RAID10 |
BTRFS_BLOCK_GROUP_DUP)) {
/* we limit the length of each bio to what fits in a stripe */
*length = min_t(u64, ce->size - offset,
map->stripe_len - stripe_offset);
} else {
*length = ce->size - offset;
}
This means, if the chunk is SINGLE profile, then we don't limit the
returned length at all, and even for other profiles, we can still return
a length much larger than the requested one.
[FIX]
Properly clamp the returned length, preventing it from returning a much
larger range than expected.

Add reset control support in USB glue logic. This needs to control

The USB dm tree when using dwc3-generic is the following:
USB glue

+-- controller-reset (need syscon-reset)
+-- phy
The controller needs to deassert "controller-reset" in USB glue before
the controller registers are accessed. The glue needs to deassert
"syscon-reset" before the glue registers are accessed.
The glue itself doesn't have "syscon-reset", so the controller-reset
controls "syscon-reset" instead.

The most of devicetree has the following USB node structure.
The controller node is placed as a child node of the glue node.
Current dwc3-generic driver works on this premise.
glue {
/* glue node */
usb {
/* controller node */
};
};
However, UniPhier original devicetree has the following USB node structure.
The controller node is separately placed from the glue node.
usb {
/* controller node */
};
glue {
/* glue node */
};
In dwc_glue_bind(), this patch provides .glue_get_ctrl_dev() callback to
get such a controller node and binds the driver related to the node.
If this callback isn't defined, dwc_glue_bind() looks for the controller
nodes from the child nodes, as before.

- in top level glue node, with generic subnode without clock (ZynqMP)
- in top level generic node, with no subnode (i.MX8MQ)
- in generic subnode, with other clock in top level node (i.MX8MP)
- in both top level node and generic subnode (Rockchip)
