Merge tag 'regulator-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown: "A fairly quiet release, there were some cleanup and a couple of new devices but the biggest change was converting most of the drivers to use asynchronous probe. This allows us to ramp up multiple regulators in parallel during boot which can have a noticable impact on modern systems.
Summary:
- Update of drivers to PROBE_PREFER_ASYNCHRONOUS to mitigate issues with ramp times slowing down boots.
- Convert to void remove callbacks.
- Support for voltage monitoring on DA9063
- Support for Qualcomm PMC8180 and PMM8654au, Richtek RT4803 and RT5739, Rockchip RK860x"

regulator: Set PROBE_PREFER_ASYNCHRONOUS for
Merge series from Douglas Anderson <dianders@chromium.org>:
This series directly follows from the discussion when I tried to turn on PROBE_PREFER_ASYNCHRONOUS just for the fixed-regulator [1] and attempts to switch everything in drivers/regulator over to async probe.
Like the similar patch series I did for the MMC subsystem a few years ago [2], I've split this patch series into batches corresponding to drivers corresponding to actively maintained stable kernel trees with the idea to break the patch series up somewhat.
Most of the description of this series is contained in the first patch of the series and then the further patches simply refer back to the first one. The logic and reasoning behind all the patches is exactly the same.
As talked about in the first patch, it wouldn't be at all shocking if this broke someone. Hopefully this doesn't cause too much of a problem. Most of the problems expected would be real underlying bugs that already existed and were just tickled by this change. If you're facing a problem, it's fairly easy to force individual drivers back to "synchronous" probing while the problem is tracked down and fixed.
I am opting _not_ to CC every single person involved in each of these regulators on this patch series because I suspect that the mailing lists couldn't handle CCing that many people. This should be on LKML so hopefully people can find it there and respond to it that way. Anyone who responds will get CCed on future versions, if there are any.
For reference, the ugly script I used is here: import os import re
for filename in os.listdir("."): found_subsys = False found_driver = False output = [] for line in open(filename, "r").readlines(): if "struct platform_driver" in line or \ "struct i2c_driver" in line or \ "struct spmi_driver" in line or \ "struct spi_driver" in line: found_subsys = True if found_subsys and re.search(r"\t\.driver\s*=\s*{", line): found_driver = True found_subsys = False mo = re.search(r"(\s*)\.name(\s*)=", line) if found_driver and mo: if not line.endswith(",\n"): line = line[:-1] + ",\n" output.append(line)
if mo.group(2) == " ": space = " " elif mo.group(2) == "\t": # Best we can do space = " " elif mo.group(2).startswith("\t"): # Guess that removing one tab is right space = mo.group(2)[1:] else: # Guess it's all spaces space = mo.group(2)[7:] + " "
output.append("%s.probe_type%s= PROBE_PREFER_ASYNCHRONOUS,\n" % (mo.group(1), space)) found_driver = False else: output.append(line)
open(filename, "w").write("".join(output))
I manually split drivers up into groups based on the kernel they were introduced in.
I've run a compile test against "allyesconfig" on amd64, arm32, and arm64 with this and confirmed it compiled. I've booted this on a sc7180-trogdor-lazor board and confirmed it booted OK and got the boot speed improvements I expected and that dmesg was as expected.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14
Probing of regulators can be a slow operation and can contribute to slower boot times. This is especially true if a regulator is turned on at probe time (with regulator-boot-on or regulator-always-on) and the regulator requires delays (off-on-time, ramp time, etc).
While the overall kernel is not ready to switch to async probe by default, as per the discussion on the mailing lists [1] it is believed that the regulator subsystem is in good shape and we can move regulator drivers over wholesale. There is no way to just magically opt in all regulators (regulators are just normal drivers like platform_driver), so we set PROBE_PREFER_ASYNCHRONOUS for all regulators found in 'drivers/regulator' individually.
Given the number of drivers touched and the impossibility to test this ahead of time, it wouldn't be shocking at all if this caused a regression for someone. If there is a regression caused by this patch, it's likely to be one of the cases talked about in [1]. As a "quick fix", drivers involved in the regression could be fixed by changing them to PROBE_FORCE_SYNCHRONOUS. That being said, the correct fix would be to directly fix the problem that caused the issue with async probe.
The approach here follows a similar approach that was used for the mmc subsystem several years ago [2]. In fact, I ran nearly the same python script to auto-generate the changes. The only thing I changed was to search for "i2c_driver", "spmi_driver", and "spi_driver" in addition to "platform_driver".

Merge branch 'sg_nents' into rdma.git for-next
From Maor Gottlieb ====================
Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges.
Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases.
====================
