Remove legacy binding egalax-ts.txt file. And add compatible string
eeti,egalax_ts and wakeup-gpios to eeti,exc3000.yaml. "eeti,egalax_ts" is
general compatible string, which is not preferred. But it is compatible
with old devices (older than 10 years) and existing driver in
drivers/input/touchscreen/egalax_ts.c.
Allow address 0x4 for eeti,egalax_ts.
Don't require touchscreen-size-x(y) for eeti,egalax_ts.
Keep the same restriction for existing compatible string.
Fix below DTB_CHECKS warnings:

Currently, the usb251xb assumes i2c control, but from HW point of
view, the hub supports usage case without any i2c control, I.E we
only want the gpio controls, for example the following dt node:
usb-hub {
compatible = "microchip,usb2512b";
reset-gpios = <&porta 8 GPIO_ACTIVE_LOW>;
};
Modify the dt-binding of usb2512b to support this usage case, and add
the usage example to the examples section.

Redundant data is used to enhance data fault tolerance, and the storage
method for redundant data vary depending on the RAID levels. And it's
important to maintain the consistency of redundant data.
Bitmap is used to record which data blocks have been synchronized and which
ones need to be resynchronized or recovered. Each bit in the bitmap
represents a segment of data in the array. When a bit is set, it indicates
that the multiple redundant copies of that data segment may not be
consistent. Data synchronization can be performed based on the bitmap after
power failure or readding a disk. If there is no bitmap, a full disk
synchronization is required.
Due to known performance issues with md-bitmap and the unreasonable
implementations:
- self-managed IO submitting like filemap_write_page();
- global spin_lock
I have decided not to continue optimizing based on the current bitmap
implementation, this new bitmap is invented without locking from IO fast
path and can be used with fast disks.
For designs and details, see the comments in drivers/md-llbitmap.c.

Pull spi fixes from Mark Brown:
"The largest batch of fixes here is a series of fixes for the Freescale
LPSPI driver which James Clark pulled out of their BSP while looking
at support for the NXP S32G version of the controller.
The majority of this turned out to be bug fixes that affect existing
systems with the actual S32G support being just a small quirk that
would be unremarkable by itself, the whole series has had a good
amount of testing and review and the individual patches are all pretty
straightforward by themselves.
We also have a few other driver specific fixes, including a relatively
large but simple one for the Cadence QuadSPI driver"

I wrote this driver to read settings and state from the nxp pf530x

These sysctl knobs were scheduled for removal in September 2025. That
time has come, so remove them.

Absolute majority of callers are passing the 4th argument equal to
strlen() of the 3rd one.
Drop the v_size argument, add vfs_parse_fs_qstr() for the cases that
