Merge tag 'i2c-host-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow
The DesignWare and the Renesas I2C drivers have received most of the changes in this pull request.
The first has has undergone through a series of cleanups that have been sent to the mailing list a year ago for the first time and finally get merged in this pull request. They are many, from typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline functions to librarieas) and many others.
Besides that, all the DesignWare Kconfig options have been grouped under the I2C_DESIGNWARE_CORE and this required some adaptation in many of the kernel configuration files for different arm and mips boards.
Follows the list of the rest of the changes grouped by type of change.
Cleanups -------- The Qualcomm Geni platform improves the exit path in the runtime resume function.
The Intel LJCA driver loses "target_addr" parameter in ljca_i2c_stop() because it was unused.
The MediaTek controller intializes the restart_flag in the transfer function using the ternary conditional operator ("? :") instead of initializing it in different parts.
Constified a few global data structures in the virtio driver.
The Renesas driver simplifies the bus speed handling in the init function making it more readable.
Improved an if/else statement in probe function of the Renesas R-Car driver.
The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead of SET_RUNTIME_PM_OPS().
Still in the iMX/MXC driver a comma ',' has been replaced by a semicolon ';', while in different drivers the ',' has been removed from the '{ }' delimiters.
Finally three devm_clk_get_enabled() have been used to simplify the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2, Ingenic and MPC drivers.
Refactors --------- The Nuvoton fixes a potential out of boundary array access. This is not a bug fix because the issue could never occur due to hardware not having the properties listed in the array. The change makes the driver more future proof and, at the same time, silences code analyzers.
Improvements ------------ The Renesas I2C (riic) driver undergoes several patches improving the runtime power management handling.
The Intel i801 driver uses a more descriptive adapter's name to show the presence of the IDF feature.
In the Intel Denverton (ismt) adapter the pending transactions are killed when irq's can't complete their handling, triggering a timeout. This could have been considered as a bug fix, but because, standing to Vasily, it's very sporadic, I preferred considering the patch rather as an improvement.
New Feature ----------- The Renesas I2C (riic) driver now supports the fast mode plus.
New support ----------- Added support for:
- Renesas R9A08G045 - Rockchip RK3576 - KEBA I2C - Theobroma Systems Mule Multiplexer.
The Keba comes with a new driver, i2c-keba.c. The Mule is an i2c multiplexer and it also comes with a new driver, mux/i2c-mux-mule.c.
Core patch ---------- This pull request includes also a patch in the I2C framework, in i2c-core-base.c where the runtime PM functions have been replaced in order to allow to be accessed during the device add.
Devicetree ---------- Some cleanups in the devicetree, as well. nVidia and Qualcomm bindings improve their "if:then:" blocks. While the aspeed binding loses the "multi-master" property because it was redundant.
The i2c-sprd binding has been converted to YAML.

nfsd: fix delegation_blocked() to block correctly for at least 30 seconds
The pair of bloom filtered used by delegation_blocked() was intended to block delegations on given filehandles for between 30 and 60 seconds. A new filehandle would be recorded in the "new" bit set. That would then be switch to the "old" bit set between 0 and 30 seconds later, and it would remain as the "old" bit set for 30 seconds.
Unfortunately the code intended to clear the old bit set once it reached 30 seconds old, preparing it to be the next new bit set, instead cleared the *new* bit set before switching it to be the old bit set. This means that the "old" bit set is always empty and delegations are blocked between 0 and 30 seconds.
This patch updates bd->new before clearing the set with that index, instead of afterwards.

NFSD: Limit the number of concurrent async COPY operations
Nothing appears to limit the number of concurrent async COPY operations that clients can start. In addition, AFAICT each async COPY can copy an unlimited number of 4MB chunks, so can run for a long time. Thus IMO async COPY can become a DoS vector.
Add a restriction mechanism that bounds the number of concurrent background COPY operations. Start simple and try to be fair -- this patch implements a per-namespace limit.
An async COPY request that occurs while this limit is exceeded gets NFS4ERR_DELAY. The requesting client can choose to send the request again after a delay or fall back to a traditional read/write style copy.
If there is need to make the mechanism more sophisticated, we can visit that in future patches.

nfsd: avoid races with wake_up_var()
wake_up_var() needs a barrier after the important change is made in the var and before wake_up_var() is called, else it is possible that a wake up won't be sent when it should.
In each case here the var is changed in an "atomic" manner, so smb_mb__after_atomic() is sufficient.
In one case the important change (removing the lease) is performed *after* the wake_up, which is backwards. The code survives in part because the wait_var_event is given a timeout.
This patch adds the required barriers and calls destroy_delegation() *before* waking any threads waiting for the delegation to be destroyed.
