Linus Torvalds 6cfae0c26b Char/Misc driver patches for 5.4-rc1
Here is the big char/misc driver pull request for 5.4-rc1.
 
 As has been happening in previous releases, more and more individual
 driver subsystem trees are ending up in here.  Now if that is good or
 bad I can't tell, but hopefully it makes your life easier as it's more
 of an aggregation of trees together to one merge point for you.
 
 Anyway, lots of stuff in here:
 	- habanalabs driver updates
 	- thunderbolt driver updates
 	- misc driver updates
 	- coresight and intel_th hwtracing driver updates
 	- fpga driver updates
 	- extcon driver updates
 	- some dma driver updates
 	- char driver updates
 	- android binder driver updates
 	- nvmem driver updates
 	- phy driver updates
 	- parport driver fixes
 	- pcmcia driver fix
 	- uio driver updates
 	- w1 driver updates
 	- configfs fixes
 	- other assorted driver updates
 
 All of these have been in linux-next for a long time with no reported
 issues.

 why...
 
 Anyway, here's the TTY and Serial driver update for 5.4-rc1.  Lots of
 changes in here for a number of embedded serial port devices that are
 being worked on because people really like to see those console logs...
 
 Other than that, nothing major here, no core tty changes that anyone

Linus Torvalds 1f7d290a72 Driver core patches for 5.4-rc1
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported
 issues.

Linus Torvalds 7c672abc12 It's a somewhat calmer cycle for docs this time, as the churn of the mass
RST conversion is happily mostly behind us.
 
  - A new document on reproducible builds.
 
  - We finally got around to zapping the documentation for hardware support
    that was removed in 2004; one doesn't want to rush these things.
 
  - The usual assortment of fixes, typo corrections, etc.
 
 You'll still find a handful of annoying conflicts against other trees,
 mostly tied to the last RST conversions; resolutions are straightforward
 and the linux-next ones are good.

Linus Walleij fdd61a013a gpio: Add support for hierarchical IRQ domains
Hierarchical IRQ domains can be used to stack different IRQ
controllers on top of each other.

Bring hierarchical IRQ domains into the GPIOLIB core with the
following basic idea:

Drivers that need their interrupts handled hierarchically
specify a callback to translate the child hardware IRQ and
IRQ type for each GPIO offset to a parent hardware IRQ and
parent hardware IRQ type.

Users have to pass the callback, fwnode, and parent irqdomain
before calling gpiochip_irqchip_add().

We use the new method of just filling in the struct
gpio_irq_chip before adding the gpiochip for all hierarchical
irqchips of this type.

The code path for device tree is pretty straight-forward,
while the code path for old boardfiles or anything else will
be more convoluted requireing upfront allocation of the
interrupts when adding the chip.

One specific use-case where this can be useful is if a power
management controller has top-level controls for wakeup
interrupts. In such cases, the power management controller can
be a parent to other interrupt controllers and program
additional registers when an IRQ has its wake capability
enabled or disabled.

The hierarchical irqchip helper code will only be available
when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using
this should select or depend on that symbol. When using
hierarchical IRQs, the parent interrupt controller must
also be hierarchical all the way up to the top interrupt
controller wireing directly into the CPU, so on systems
that do not have this we can get rid of all the extra
code for supporting hierarchical irqs.

Rafael J. Wysocki 515db266a9 driver core: Remove device link creation limitation
If device_link_add() is called for a consumer/supplier pair with an
existing device link between them and the existing link's type is
not in agreement with the flags passed to that function by its
caller, NULL will be returned.  That is seriously inconvenient,
because it forces the callers of device_link_add() to worry about
what others may or may not do even if that is not relevant to them
for any other reasons.

It turns out, however, that this limitation can be made go away
relatively easily.

The underlying observation is that if DL_FLAG_STATELESS has been
passed to device_link_add() in flags for the given consumer/supplier
pair at least once, calling either device_link_del() or
device_link_remove() to release the link returned by it should work,
but there are no other requirements associated with that flag.  In
turn, if at least one of the callers of device_link_add() for the
given consumer/supplier pair has not passed DL_FLAG_STATELESS to it
in flags, the driver core should track the status of the link and act
on it as appropriate (ie. the link should be treated as "managed").
This means that DL_FLAG_STATELESS needs to be set for managed device
links and it should be valid to call device_link_del() or
device_link_remove() to drop references to them in certain
sutiations.

To allow that to happen, introduce a new (internal) device link flag
called DL_FLAG_MANAGED and make device_link_add() set it automatically
whenever DL_FLAG_STATELESS is not passed to it.  Also make it take
additional references to existing device links that were previously
stateless (that is, with DL_FLAG_STATELESS set and DL_FLAG_MANAGED
unset) and will need to be managed going forward and initialize
their status (which has been DL_STATE_NONE so far).

Accordingly, when a managed device link is dropped automatically
by the driver core, make it clear DL_FLAG_MANAGED, reset the link's
status back to DL_STATE_NONE and drop the reference to it associated
with DL_FLAG_MANAGED instead of just deleting it right away (to
allow it to stay around in case it still needs to be released
explicitly by someone).

With that, since setting DL_FLAG_STATELESS doesn't mean that the
device link in question is not managed any more, replace all of the
status-tracking checks against DL_FLAG_STATELESS with analogous
checks against DL_FLAG_MANAGED and update the documentation to
reflect these changes.

While at it, make device_link_add() reject flags that it does not
recognize, including DL_FLAG_MANAGED.

Linus Torvalds 916f562fb2 This round of clk driver and framework updates is heavy on the driver update
side. The two main highlights in the core framework are the addition of an bulk
 clk_get API that handles optional clks and an extra debugfs file that tells the
 developer about the current parent of a clk.
 
 The driver updates are dominated by i.MX in the diffstat, but that is mostly
 because that SoC has started converting to the clk_hw style of clk
 registration. The next big update is in the Amlogic meson clk driver that
 gained some support for audio, cpu, and temperature clks while fixing some PLL
 issues. Finally, the biggest thing that stands out is the conversion of a large
 part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
 less strings and more pointer comparisons to match clk parents and children up.
 
 In general, it looks like we have a lot of little fixes and tweaks here and
 there to clk data along with the normal addition of a handful of new drivers
 and a couple new core framework features.
 
 Core:
  - Add a 'clk_parent' file in clk debugfs
  - Add a clk_bulk_get_optional() API (with devm too)
 
 New Drivers:
  - Support gated clk controller on MIPS based BCM63XX SoCs
  - Support SiLabs Si5341 and Si5340 chips
  - Support for CPU clks on Raspberry Pi devices
  - Audsys clock driver for MediaTek MT8516 SoCs
 
 Updates:
  - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
  - Small frequency support for SiLabs Si544 chips
  - Slow clk support for AT91 SAM9X60 SoCs
  - Remove dead code in various clk drivers (-Wunused)
  - Support for Marvell 98DX1135 SoCs
  - Get duty cycle of generic pwm clks
  - Improvement in mmc phase calculation and cleanup of some rate defintions
  - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
  - Add GPIO, SNVS and GIC clocks for i.MX8 drivers
  - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
  - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
  - Add clks for new Exynos5422 Dynamic Memory Controller driver
  - Clock definition for Exynos4412 Mali
  - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
  - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
  - TI clock probing done from DT by default instead of firmware
  - Fix Amlogic Meson mpll fractional part and spread sprectrum issues
  - Add Amlogic meson8 audio clocks
  - Add Amlogic g12a temperature sensors clocks
  - Add Amlogic g12a and g12b cpu clocks
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
  - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W
  - Add Clock Domain support on Renesas RZ/N1
