dmaengine: bcm2708: Remove chancnt affectations
Mirror bcm2835-dma.c commit 9eba5536a7:
chancnt is already filled by dma_async_device_register, which uses the channel
list to know how much channels there is.
Since it's already filled, we can safely remove it from the drivers' probe
function.

Only overwrite dreq with slave_id if it is not set.
dreq/slave_id in the cyclic DMA case is not touched, because I don't

dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
Merge the legacy DMA API driver with bcm2708-dmaengine.
This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
driver is also needed).
Changes to the dma.c code:
- Use BIT() macro.
- Cutdown some comments to one line.
- Add mutex to vc_dmaman and use this, since the dev lock is locked
during probing of the engine part.
- Add global g_dmaman variable since drvdata is used by the engine part.
- Restructure for readability:
vc_dmaman_chan_alloc()
vc_dmaman_chan_free()
bcm_dma_chan_free()
- Restructure bcm_dma_chan_alloc() to simplify error handling.
- Use device irq resources instead of hardcoded bcm_dma_irqs table.
- Remove dev_dmaman_register() and code it directly.
- Remove dev_dmaman_deregister() and code it directly.
- Simplify bcm_dmaman_probe() using devm_* functions.
- Get dmachans from DT if available.
- Keep 'dma.dmachans' module argument name for backwards compatibility.
Make it available on ARCH_BCM2835 as well.

dmaengine: bcm2708: set residue_granularity field
bcm2708-dmaengine supports residue reporting at burst level
but didn't report this via the residue_granularity field.
Without this field set properly we get playback issues with I2S cards.
dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
bcm2708-dmaengine: Use more DMA channels (but not 12)
1) Only the bcm2708_fb drivers uses the legacy DMA API, and
it requires a BULK-capable channel, so all other types
(FAST, NORMAL and LITE) can be made available to the regular
DMA API.
2) DMA channels 11-14 share an interrupt. The driver can't
handle this, so don't use channels 12-14 (12 was used, probably
because it appears to have an interrupt, but in reality that
interrupt is for activity on ANY channel). This may explain
a lockup encountered when running out of DMA channels.
The combined effect of this patch is to leave 7 DMA channels
available + channel 0 for bcm2708_fb via the legacy API.
See: https://github.com/raspberrypi/linux/issues/1110https://github.com/raspberrypi/linux/issues/1108
dmaengine: bcm2708: Make legacy API available for bcm2835-dma
bcm2708_fb uses the legacy DMA API, so in order to start using
bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().

bcm2708-dmaengine - Fix arm64 portability/build issues
dma-bcm2708: Fix module compilation of CONFIG_DMA_BCM2708
bcm2708-dmaengine.c defines functions like bcm_dma_start which are
defined as well in dma-bcm2708.h as inline versions when
CONFIG_DMA_BCM2708 is not defined. This works fine when
CONFIG_DMA_BCM2708 is built in, but when it is selected as module build
fails with redefinition errors because in the build system when
CONFIG_DMA_BCM2708 is selected as module, the macro becomes
CONFIG_DMA_BCM2708_MODULE.
This patch makes the header use CONFIG_DMA_BCM2708_MODULE too when
available.

Pull clk updates from Stephen Boyd:
"Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
divider type and add a power of two fractional divider flag though.
Otherwise, this is a collection of clk driver updates. More than half
the diffstat is in the Qualcomm clk driver where we add a bunch of
data to describe clks on various SoCs and fix bugs. The other big new
thing in here is the Mediatek MT8192 clk driver. That's been under
review for a while and it's nice to see that it's finally upstream.
Beyond that it's the usual set of minor fixes and tweaks to clk
drivers. There are some non-clk driver bits in here which have all
been acked by the respective maintainers.
New Drivers:
- Support video, gpu, display clks on qcom sc7280 SoCs
- GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
- Multimedia clks (MMCC) on qcom MSM8994/MSM8992

- Support for Mediatek MT8192 SoCs
- Add display (DU and DSI) clocks on Renesas R-Car V3U
- Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
resets on Renesas RZ/G2L

- Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
- Add power of two flag to fractional divider clk type
- Migrate some clk drivers to clk_divider_ops.determine_rate
- Migrate to clk_parent_data in gcc-sdm660

In Windows the ASUS Armory Crate program can enable or disable the
dGPU via a WMI call. This functions much the same as various Linux
methods in software where the dGPU is removed from the device tree.
However the WMI call saves the state of dGPU (enabled or not) and
this then changes the dGPU visibility in Linux with no way for
Linux users to re-enable it. We expose the WMI method so users can
see and change the dGPU ACPI state.

This driver creates a sysfs node for each peripheral charge port:
/sys/class/power_supply/peripheral<n>
where <n> is the index of a charge port.
For example, when a stylus is connected to a NFC/WLC port, the node
returns:

Pull staging / IIO driver updates from Greg KH:
"Here is the big set of IIO and staging driver patches for 5.14-rc1.
Loads of IIO driver updates and additions in here, the shortlog has
the full details.
For the staging side, we moved a few drivers out of staging, and
deleted the kpc2000 drivers as the original developer asked us to
because no one was working on them anymore.
Also in here are loads of coding style cleanups due to different
intern projects focusing on the staging tree to try to get experience
doing kernel development.
All of these have been in the linux-next tree for a while with no

This is a major chunk of IXP4xx modernization:
- Fist we move some registers around to make room for
the predetermined PCI I/O space.
- Then we add some Kconfig options to make it possible
to use the old PCI driver in parallell with the new
shiny one.
- Then we add the new PCI driver and some bindings for
it.
- On top of this we add an (ages old) patch from Arnd
that centralize the CPU/SoC detection in drivers/soc
and make the header a standard Linux header to avoid
the <mach/*> business in drivers.
- Then we split out and modernize some platform data
headers for pata, and hwrandom, and top it up with
DT bindings and support for hwrandom.

On am335x, suspend and resume only works once, and the system hangs if
suspend is attempted again. However, turns out suspend and resume works
fine multiple times if the USB OTG driver for musb controller is loaded.
The issue is caused my the interconnect target module losing context
during suspend, and it needs a restore on resume to be reconfigure again
as debugged earlier by Dave Gerlach <d-gerlach@ti.com>.
There are also other modules that need a restore on resume, like gpmc as
noted by Dave. So let's add a common way to restore an interconnect
target module based on a quirk flag. For now, let's enable the quirk for
am335x otg only to fix the suspend and resume issue.
As gpmc is not causing hangs based on tests with BeagleBone, let's patch
gpmc separately. For gpmc, we also need a hardware reset done before
restore according to Dave.
To reinit the modules, we decouple system suspend from PM runtime. We
replace calls to pm_runtime_force_suspend() and pm_runtime_force_resume()
with direct calls to internal functions and rely on the driver internal
state. There no point trying to handle complex system suspend and resume
quirks via PM runtime.
This is issue should have already been noticed with commit 1819ef2e2d
("bus: ti-sysc: Use swsup quirks also for am335x musb") when quirk
handling was added for am335x otg for swsup. But the issue went unnoticed
as having musb driver loaded hides the issue, and suspend and resume works
once without the driver loaded.
Fixes: 1819ef2e2d ("bus: ti-sysc: Use swsup quirks also for am335x musb")

Pull sound updates from Takashi Iwai:
"No surprises in this development cycle, and most of work is about the
fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced. It is used by HD-audio
for now, more adaption will follow later. The former "Mic Mute-LED
Mode" mixer control has been replaced with the corresponding sysfs
now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements; this will allow more controls in
the normal usage pattern while avoiding the possible memory
exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates"

Pull staging/IIO driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for this
failed "experiment".
- removal of the Google gasket driver, turns out no one wanted to
maintain it or cares about it anymore, so they asked for it to be
removed.
- comedi finally moves out of the staging directory into drivers/comedi
This is one of the oldest kernel subsystems around, being created
in the 2.0 kernel days, and was one of the first things added to
drivers/staging/ when that was created over 15 years ago.
It should have been moved out of staging a long time ago, it's well
maintained and used by loads of different devices in the real world
every day. Nice to see this finally happen.
- so many tiny coding style cleanups it's not funny.
Perfect storm of at least 2 different intern project application
deadlines combined to provide a huge number of new contributions in
this area from people learning how to do kernel development. Great
job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers
and updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues"

This adds device tree probing to the IXP4xx ethernet
driver.
Add a platform data bool to tell us whether to
register an MDIO bus for the device or not, as well
as the corresponding NPE.
We need to drop the memory region request as part of
this since the OF core will request the memory for the
device.

As we are using cpu_pm to save and restore context, we must also save and
restore the GPIO sysconfig register. This is needed because we are not
calling PM runtime functions at all with cpu_pm.
We need to save the sysconfig on idle as it's value can get reconfigured by
PM runtime and can be different from the init time value. Device specific
flags like "ti,no-idle-on-init" can affect the init value.
Fixes: b764a5863f ("gpio: omap: Remove custom PM calls and use cpu_pm instead")
