There's an inconsistency that arises when a register set can be accessed
internally via MMIO, or externally via SPI. The VSC7514 chip allows both
modes of operation. When internally accessed, the system utilizes __iomem,
devm_ioremap_resource, and devm_regmap_init_mmio.
For SPI it isn't possible to utilize memory-mapped IO. To properly operate,
the resource base must be added to the register before every operation.

Add an additional reg_downshift to be applied to register addresses before
any register accesses. An example of a device that uses this is a VSC7514
chip, which require each register address to be downshifted by two if the
access is performed over a SPI bus.

With the existing logic where clear_ack is true (HW doesn’t support
auto clear for ICR), interrupt clear register reset is not handled
properly. Due to this only the first interrupts get processed properly
and further interrupts are blocked due to not resetting interrupt
clear register.
Example for issue case where Invert_ack is false and clear_ack is true:
Say Default ISR=0x00 & ICR=0x00 and ISR is triggered with 2
interrupts making ISR = 0x11.
Step 1: Say ISR is set 0x11 (store status_buff = ISR). ISR needs to
be cleared with the help of ICR once the Interrupt is processed.
Step 2: Write ICR = 0x11 (status_buff), this will clear the ISR to 0x00.
Step 3: Issue - In the existing code, ICR is written with ICR =
~(status_buff) i.e ICR = 0xEE -> This will block all the interrupts
from raising except for interrupts 0 and 4. So expectation here is to
reset ICR, which will unblock all the interrupts.
if (chip->clear_ack) {
if (chip->ack_invert && !ret)
........
else if (!ret)
ret = regmap_write(map, reg,
~data->status_buf[i]);
So writing 0 and 0xff (when ack_invert is true) should have no effect, other
than clearing the ACKs just set.

Since commit cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when
calling regmap_attach_dev"), the following debugfs error is seen
on i.MX boards:
debugfs: Directory 'dummy-iomuxc-gpr@20e0000' with parent 'regmap' already present!
In the attempt to fix the memory leak, the above commit added a NULL check
for map->debugfs_name. For the first debufs entry, map->debugfs_name is NULL
and then the new name is allocated via kasprintf().
For the second debugfs entry, map->debugfs_name() is no longer NULL, so
it will keep using the old entry name and the duplicate name error is seen.
Quoting Mark Brown:
"That means that if the device gets freed we'll end up with the old debugfs
file hanging around pointing at nothing.
...
To be more explicit this means we need a call to regmap_debugfs_exit()
which will clean up all the existing debugfs stuff before we loose
references to it."
Call regmap_debugfs_exit() prior to regmap_debugfs_init() to fix
the problem.
Tested on i.MX6Q and i.MX6SX boards.

Some device requires a special handling for reg_update_bits and can't use
the normal regmap read write logic. An example is when locking is
handled by the device and rmw operations requires to do atomic operations.
Allow to declare a dedicated function in regmap_config for
reg_update_bits in no bus configuration.

Oltean <vladimir.oltean@nxp.com>:
The ls-extirq irqchip driver accesses regmap inside its implementation
of the struct irq_chip :: irq_set_type method, and currently regmap
only knows to lock using normal spinlocks. But the method above wants
raw spinlock context, so this isn't going to work and triggers a
"[ BUG: Invalid wait context ]" splat.
The best we can do given the arrangement of the code is to patch regmap
and the syscon driver: regmap to support raw spinlocks, and syscon to
request them on behalf of its ls-extirq consumer.

Some drivers might access regmap in a context where a raw spinlock is
held. An example is drivers/irqchip/irq-ls-extirq.c, which calls
regmap_update_bits() from struct irq_chip :: irq_set_type, which is a
method called by __irq_set_trigger() under the desc->lock raw spin lock.
Since desc->lock is a raw spin lock and the regmap internal lock for
mmio is a plain spinlock (which can become sleepable on RT), this is an
invalid locking scheme and we get a splat stating that this is a
"[ BUG: Invalid wait context ]".
It seems reasonable for regmap to have an option use a raw spinlock too,
so add that in the config such that drivers can request it.

The reg_fields array fed to {devm_}regmap_field_bulk_alloc is currently
not const, which is not correct on semantics (the functions shouldn't
change reg_field contents) and prevents pre-defined const reg_field

As the implementation of this function doesn't change the content of it,
just add const to its prototype.

<sander@svanheule.net>:
The RTL8231 GPIO and LED expander can be configured for use as an MDIO or SMI
bus device. Currently only the MDIO mode is supported, although SMI mode
support should be fairly straightforward, once an SMI bus driver is available.
Provided features by the RTL8231:
- Up to 37 GPIOs
- Configurable drive strength: 8mA or 4mA (currently unsupported)
- Input debouncing on high GPIOs (currently unsupported)
- Up to 88 LEDs in multiple scan matrix groups
- On, off, or one of six toggling intervals
- "single-color mode": 2×36 single color LEDs + 8 bi-color LEDs
- "bi-color mode": (12 + 2×6) bi-color LEDs + 24 single color LEDs
- Up to one PWM output (currently unsupported)
- Fixed duty cycle, 8 selectable frequencies (1.2kHz - 4.8kHz)
Register access is provided through a new MDIO regmap provider. The GPIO
controller uses gpio-regmap, although a patch is required to support a
limitation of the chip.
There remain some log warnings when probing the device, possibly due to the way
I'm using the MFD subsystem. Would it be possible to avoid these?

Changes since RFC:
- Dropped MDIO regmap interface. I was unable to resolve the Kconfig
dependency issue, so have reverted to using regmap_config.reg_read/write.
- Added pinctrl support
- Added LED support
- Changed root device to MFD, with pinctrl and leds child devices. Root
device is now an mdio_device driver.

Enable drivers to configure and modify "virtual" registers, which are
non-standard registers that further configure irq type on some devices.
Since they are non-standard, enable drivers to configure them according
to their particular idiosyncrasies by specifying an optional callback
function while registering with the framework.

Add "virtual" registers support to handle any irq configuration
registers in addition to the ones the framework currently supports
(status, mask, unmask, wake, type and ack). These are non-standard
registers that further configure irq type on some devices, so enable the
framework to add a variable number of them.

Qualcomm's MFD chips have a top level interrupt status register and
sub-irqs (peripherals). When a bit in the main status register goes
high, it means that the peripheral corresponding to that bit has an
unserviced interrupt. If the bit is not set, this means that the
corresponding peripheral does not.
Commit a2d21848d9211d ("regmap: regmap-irq: Add main status register
support") introduced the sub-irq logic that is currently applied only
when reading status registers, but not for any other functions like acking
or masking. Extend the use of sub-irq to all other functions, with two
caveats regarding the specification of offsets:
- Each member of the sub_reg_offsets array should be of length 1
- The specified offsets should be the unequal strides for each sub-irq
device.
In QCOM's case, all the *_base registers are to be configured to the
base addresses of the first sub-irq group, with offsets of each
subsequent group calculated as a difference from these addresses.
Continuing from the example mentioned in the cover letter:
/*
* Address of MISC_INT_MASK = 0x1011
* Address of TEMP_ALARM_INT_MASK = 0x2011
* Address of GPIO01_INT_MASK = 0x3011
*
* Calculate offsets as:
* offset_0 = 0x1011 - 0x1011 = 0 (to access MISC's
* registers)
* offset_1 = 0x2011 - 0x1011 = 0x1000
* offset_2 = 0x3011 - 0x1011 = 0x2000
*/
static unsigned int sub_unit0_offsets[] = {0};
static unsigned int sub_unit1_offsets[] = {0x1000};
static unsigned int sub_unit2_offsets[] = {0x2000};
static struct regmap_irq_sub_irq_map chip_sub_irq_offsets[] = {

There is a upstream commit cffa4b2122f5("regmap:debugfs:
Fix a memory leak when calling regmap_attach_dev") that
adds a if condition when create name for debugfs_name.
With below function invoking logical, debugfs_name is
freed in regmap_debugfs_exit(), but it is not created again
because of the if condition introduced by above commit.
regmap_reinit_cache()
regmap_debugfs_exit()
...
regmap_debugfs_init()
So, set debugfs_name to NULL after it is freed.

sdw_update_slave_status will be invoked when a codec is attached,
and the codec driver will initialize the codec with regmap functions
while the codec device is pm_runtime suspended.
regmap routines currently rely on regular SoundWire IO functions,
which will call pm_runtime_get_sync()/put_autosuspend.
This causes a deadlock where the resume routine waits for an
initialization complete signal that while the initialization complete
can only be reached when the resume completes.
The only solution if we allow regmap functions to be used in resume
operations as well as during codec initialization is to use _no_pm
routines. The duty of making sure the bus is operational needs to be
handled above the regmap level.

Liao <yung-chuan.liao@linux.intel.com>:
The MIPI SoundWire Device Class standard will define audio functionality
beyond the scope of the existing SoundWire 1.2 standard, which is limited
to the bus and interface.
The description is inspired by the USB Audio Class, with "functions",
"entities", "control selectors", "audio clusters". The main difference
with the USB Audio class is that the devices are typically on a motherboard
and descriptors stored in platform firmware instead of being retrieved
from the device.
The current set of devices managed in this patchset are conformant with the
SDCA 0.6 specification and require dedicated drivers since the descriptors
and platform firmware specification is not complete at this time. They do
however rely on the hierarchical addressing required by the SDCA standard.
Future devices conformant with SDCA 1.0 should rely on a class driver.
This series adds support for the hierarchical SDCA addressing and extends
regmap. It then provides 3 codecs for RT711-sdca headset codec, RT1316
amplifier and RT715-scda microphone codec.
Note that the release of this code before the formal adoption of the
SDCA 1.0 specification was formally endorsed by the MIPI Board to make
sure there is no delay for Linux-based support of this specification.

2.17.1

The SoundWire 1.1 specification only allowed for reads and writes of
bytes. The SoundWire 1.2 specification adds a new capability to
transfer "Multi-Byte Quantities" (MBQ) across the bus. The transfers
still happens one-byte-at-a-time, but the update is atomic.
For example when writing a 16-bit volume, the first byte transferred
is only taken into account when the second byte is successfully
transferred.
The mechanism is symmetrical for read and writes:
- On a read, the address of the last byte to be read is modified by
setting the MBQ bit
- On a write, the address of all but the last byte to be written are
modified by setting the MBQ bit. The address for the last byte relies
on the MBQ bit being cleared.
The current definitions for MBQ-based controls in the SDCA draft
standard are limited to 16 bits for volumes, so for now this is the
only supported format. An update will be provided if and when support
for 24-bit and 32-bit values is specified by the SDCA standard.
One possible objection is that this code could have been handled with
regmap-sdw.c. However this is a new spec addition not handled by every
SoundWire 1.1 and non-SDCA device, so there's no reason to load code
that will never be used.
Also in practice it's extremely unlikely that CONFIG_REGMAP would not
be selected with CONFIG_REGMAP_MBQ selected. However there's no

I have an error saying that `regcache_sync` has 2 fields named `type`
while using libtraceevent.
Erase the `int field` type, which is not assigned. This field is
introduced by mistake and this commit removes it.
Fixes: 593600890110c ("regmap: Add the regcache_sync trace event")
