Subject: [PATCH net-next v2 0/6] rust: Add IO polling

Add Rust version of read_poll_timeout (include/linux/iopoll.h), which
polls periodically until a condition is met or a timeout is reached.
By using the function, the 6th patch fixes QT2025 PHY driver to sleep
until the hardware becomes ready.

As a result of the past discussion, this introduces a new type
representing a span of time instead of using core::time::Duration or
time::Ktime.

Unlike the old rust branch, This adds a wrapper for fsleep() instead
of msleep(). fsleep() automatically chooses the best sleep method
based on a duration.

v2:
- Introduce time::Delta instead of core::time::Duration
- Add some trait to Ktime for calculating timeout
- Use read_poll_timeout in QT2025 driver instead of using fsleep directly
v1: https://lore.kernel.org/netdev/20241001112512.4861-1-fujita.tomonori@gmail.com/


FUJITA Tomonori (6):
  rust: time: Implement PartialEq and PartialOrd for Ktime
  rust: time: Introduce Delta type
  rust: time: Implement addition of Ktime and Delta
  rust: time: add wrapper for fsleep function
  rust: Add read_poll_timeout function
  net: phy: qt2025: wait until PHY becomes ready
