Linus Walleij 45c5775460 usb: ohci-omap: Fix descriptor conversion
There were a bunch of issues with the patch converting the
OMAP1 OSK board to use descriptors for controlling the USB
host:

- The chip label was incorrect
- The GPIO offset was off-by-one
- The code should use sleeping accessors

This patch tries to fix all issues at the same time.

Linus Torvalds e731f3146f ARM: SoC platform updates
SoC changes, a substantial part of this is cleanup of some of the older
 platforms that used to have a bunch of board files. In particular:
 
  - Removal of non-DT i.MX platforms that haven't seen activity in years,
    it's time to remove them.
  - A bunch of cleanup and removal of platform data for TI/OMAP platforms,
    moving over to genpd for power/reset control (yay!)
  - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
    closer to multiplatform support (not quite there yet, but getting
    close).
 
 THere are a few other changes too, smaller fixlets, etc. For new
 platform support, the primary ones re:
 
  - New SoC: Hisilicon SD5203, ARM926EJ-S platform.
  - Cpufreq support for i.MX7ULP

Switch the omap1510 platform ohci device to use dma_direct_set_offset

Jim Quinlan e0d072782c dma-mapping: introduce DMA range map, supplanting dma_pfn_offset
The new field 'dma_range_map' in struct device is used to facilitate the
use of single or multiple offsets between mapping regions of cpu addrs and
dma addrs.  It subsumes the role of "dev->dma_pfn_offset" which was only
capable of holding a single uniform offset and had no region bounds
checking.

The function of_dma_get_range() has been modified so that it takes a single
argument -- the device node -- and returns a map, NULL, or an error code.
The map is an array that holds the information regarding the DMA regions.
Each range entry contains the address offset, the cpu_start address, the
dma_start address, and the size of the region.

of_dma_configure() is the typical manner to set range offsets but there are
a number of ad hoc assignments to "dev->dma_pfn_offset" in the kernel
driver code.  These cases now invoke the function
dma_direct_set_offset(dev, cpu_addr, dma_addr, size).

Linus Walleij 15d157e874 usb: ohci-omap: Convert to use GPIO descriptors
The OMAP1 OHCI driver is using the legacy GPIO API to grab some
random GPIO lines. One is from the TPS65010 chip and used for
power, another one is for overcurrent and while the driver picks
this line it doesn't watch it at all.

Convert the driver and the OMAP1 OSK board file to pass these
two GPIOs as machine described GPIO descriptors.

I noticed the overcurrent GPIO line is not really used in the
code so dropped in a little comment for other developers.

afzal mohammed b75ca52177 ARM: OMAP: replace setup_irq() by request_irq()
request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.

Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.

Hence replace setup_irq() by request_irq().

ASoC: ams-delta: Take control over audio mute GPIO pins
Since commit 1137ceee76 ("ARM: OMAP1: ams-delta: Don't request unused
GPIOs"), on-board audio has appeared muted.  It has been discovered that
believed to be unused GPIO pins "hookflash1" and "hookflash2" need to be
set low for audible sound in handsfree and handset mode respectively.

According to Amstrad E3 wiki, the purpose of both pins hasn't been
clearly identified.  Original Amstrad software used to produce a high
pulse on them when the phone was taken off hook or recall was pressed.
With the current findings, we can assume the pins provide a kind of
audio mute function, separately for handset and handsfree operation
modes.

Commit 2afdb4c41d ("ARM: OMAP1: ams-delta: Fix audio permanently
muted") attempted to fix the issue temporarily by hogging the GPIO pin
"hookflash1" renamed to "audio_mute", however the fix occurred
incomplete as it restored audible sound only for handsfree mode.

Stop hogging that pin, rename the pins to "handsfree_mute" and
"handset_mute" respectively and implement appropriate DAPM event
callbacks for "Speaker" and "Earpiece" DAPM widgets.

Janusz Krzysztofik fa8397e45c ARM: OMAP1: ams-delta-fiq: Fix missing irq_ack
Non-serio path of Amstrad Delta FIQ deferred handler depended on
irq_ack() method provided by OMAP GPIO driver.  That method has been
removed by commit 693de831c6 ("gpio: omap: remove irq_ack method").
Remove useless code from the deferred handler and reimplement the
missing operation inside the base FIQ handler.

Should another dependency - irq_unmask() - be ever removed from the OMAP
GPIO driver, WARN once if missing.

Linus Torvalds f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

  Summary:

  Core:

   - When a gpio_chip request GPIOs from itself, it can now fully
     control the line characteristics, both machine and consumer flags.
     This makes a lot of sense, but took some time before I figured out

Linus Walleij 5923ea6c2c gpio: pass lookup and descriptor flags to request_own
When a gpio_chip wants to request a descriptor from itself
using gpiochip_request_own_desc() it needs to be able to specify
fully how to use the descriptor, notably line inversion
semantics. The workaround in the gpiolib.c can be removed
and cases (such as SPI CS) where we need at times to request
a GPIO with line inversion semantics directly on a chip for
workarounds, can be fully supported with this call.

Fix up some users of the API that weren't really using the
last flag to set up the line as input or output properly
but instead just calling direction setting explicitly
after requesting the line.

Linus Walleij 2e5a662de3 i2c: cbus-gpio: Switch to use GPIO descriptors
This augments the CBUS GPIO I2C driver to use GPIO
descriptors for clock, sel and data. We drop the platform
data that was only used for carrying GPIO numbers and
use machine descriptor tables instead.

Linus Walleij 01dc79cd6f
regulator: fixed/gpio: Pull inversion/OD into gpiolib
This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.

This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

Linus Torvalds 0922275ef1 ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms,
 but also a few more things:
 
 New SoC support this release:
  - NXP/Freescale i.MX7ULP (1x Cortex-A7, Cortex-M4, graphics, etc)
  - Allwinner F1C100, older platform with an ARM926-EJS (ARMv5) core
 
 Cleanups of various platforms:
  - OMAP1 ams-delta does some GPIO cleanups
  - Davinci removes of at24 platform data
  - Samsung cleans up old wakeup, PM debug and secondary core boot code
  - Renesas moves around config options and PM code to drivers/soc for
    sharing with 64-bit and more consistency
  - i.MX, Broadcom and SoCFPGA all have tweaks to lowlevel debug console setups
  - SoCFPGA adds explicit selection of ARM errata and removes some unused code
 
 This tag also contains a few patches that I had queued up as fixes for
 4.20 but didn't send in before the release.

Linus Torvalds 24dc83635f This is the bulk of GPIO changes for the v4.21 kernel series:
Core changes:
 
 - Some core changes are already in outside of this pull
   request as they came through the regulator tree, most
   notably devm_gpiod_unhinge() that removes devres refcount
   management from a GPIO descriptor. This is needed in
   subsystems such as regulators where the regulator core
   need to take over the reference counting and lifecycle
   management for a GPIO descriptor.
 
 - We dropped devm_gpiochip_remove() and devm_gpio_chip_match()
   as nothing needs it. We can bring it back if need be.
 
 - Add a global TODO so people see where we are going. This
   helps setting the direction now that we are two GPIO
   maintainers.
 
 - Handle the MMC CD/WP properties in the device tree core.
   (The bulk of patches activating this code is already
   merged through the MMC/SD tree.)
 
 - Augment gpiochip_request_own_desc() to pass a flag so
   we as gpiochips can request lines as active low or open
   drain etc even from ourselves.
 
 New drivers:
 
 - New driver for Cadence GPIO blocks.
 
 - New driver for Atmel SAMA5D2 PIOBU GPIO lines.
 
 Driver improvements:
 
 - A major refactoring of the PCA953x driver - this driver has
   been around for ages, and is now modernized to reduce code
   duplication that has stacked up and is using regmap to read
   write and cache registers.
 
 - Intel drivers are now maintained in a separate tree and
   start with a round of cleanups and unifications.

Linus Torvalds 8e61e7b5c4 sound updates for 4.21
There are no intensive changes in both ALSA and ASoC core parts while
 rather most of changes are a bunch of driver fixes and updates.
 A large diff pattern appears in ASoC TI part which now merges both
 OMAP and DaVinci stuff, but the rest spreads allover the places.
 
 Note that this pull request includes also some updates for LED trigger
 and platform drivers for mute LEDs, appearing in the diffstat as well.
 
 Some highlights:
 
 ASoC:
 - Preparatory work for merging the audio-graph and audio-graph-scu
   cards
 - A merge of TI OMAP and DaVinci directories, as both product lines
   get merged together.  Also including a few architecture changes as
   well.
 - Major cleanups of the Maxim MAX9867 driver
 - Small fixes for tablets & co with Intel BYT/CHT chips
 - Lots of rsnd updates as usual
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers
 
 HD-audio:
 - Introduce audio-mute LED trigger for replacing the former hackish
   dynamic binding
 - Huawei WMI hotkey and mute LED support
 - Refactoring of PM code and display power controls
 - Headset button support in the generic jack code
 - A few updates for Tegra
 - Fixups for HP EliteBook and ASUS UX391UA
 - Lots of updates for Intel ASoC HD-audio, including the improved DSP
   detection and the fallback binding from ASoC SST to legacy HD-audio
   controller drivers
 
 Others:
 - Updates for FireWire TASCAM and Fireface devices, some other fixes
 - A few potential Spectre v1 fixes that are all trivial

Linus Walleij 21abf10381 gpio: Pass a flag to gpiochip_request_own_desc()
Before things go out of hand, make it possible to pass
flags when requesting "own" descriptors from a gpio_chip.
This is necessary if the chip wants to request a GPIO with
active low semantics, for example.

Aaro Koskinen c7b7b5cbd0 ARM: OMAP1: fix USB configuration for device-only setups
Currently we do USB configuration only if the host mode (CONFIG_USB)
is enabled. But it should be done also in the case of device-only setups,
so change the condition to CONFIG_USB_SUPPORT. This allows to use
omap_udc on Palm Tungsten E.
