When a UHID_CREATE command is written to the uhid char device, a
copy_from_user() is done from a user pointer embedded in the command.
When the address limit is KERNEL_DS, e.g. as is the case during

I2C communication takes place through iomapped registers, or through DMA
for more than 32 bytes transfers.
MP2 controllers have two separate buses, so may accommodate up to two I2C
adapters. Those adapters are listed in the ACPI namespace with the
"AMDI0011" HID, and probed by a platform driver.

This patch adds a driver for Fixed MMIO clock.
The driver reads a clock frequency value from a single 32-bit memory
mapped register and registers it as a fixed rate clock.
It can be enabled with COMMON_CLK_FIXED_MMIO Kconfig option.

This patchset adds a driver support for Fixed Memory Mapped IO clock.
The driver reads a clock frequency value from a single 32-bit memory
mapped register and registers it as a fixed rate clock.
It can be useful for prototyping Linux on various hardware platforms.

Some Lenovo ideapad models lack a physical rfkill switch.
On Lenovo models Yoga 2 13, ideapad-laptop would wrongly report all

Document the asynchronous serdev_device_write_buf() and synchronous
serdev_device_write() functions using kernel-doc.
Specifically, mention that writing data only means that data has been
buffered by the controller, and that the synchronous helper depends on
serdev_device_write_wakeup() being call
Use zero to indicate infinite timeout for the synchronous
serdev_device_write() helper.
This allows drivers to specify an infinite timeout without knowing about
serdev implementation details, while also allowing the same timeout
argument to be used for both serdev_device_write() and
serdev_device_
Allow the synchronous serdev_device_write() helper to be interrupted.
This is useful for cases where I/O is performed on behalf of user space
and we don't want to block indefinitely when using flow control.

This series make the synchronous serdev_device_write() helper more
usable by
1) allowing drivers to pass a zero timeout to indicate that they
want to wait forever;
2) returning the number of bytes actually written (buffered)
if the helper is interrupted;
Make the synchronous serdev_device_write() helper behave analogous to
the asynchronous serdev_device_write_buf() by returning the number of
bytes written (or rather buffered) also on timeout.
This will allow drivers to distinguish the case where data was partially
written from the case where no da
