We currently allow accessing the whole SRAM bar size with
the macro SRAM_BAR_SIZE, but the actual size of the sram
region is the macro SRAM_SIZE which is only a portion of
the whole bar size. So when accessing the sram through
debugfs, use the macro SRAM_SIZE for the sram size
which is the correct macro.

This is a part of overall refactoring attempt to separate nic and the
core drivers.
Currently, there are 4 different flows, that contain very similar code.
These are the ts, nic, hwblocks and cb alloc/map flows. The similar
aspect of all these flows is that they all contain a central store, with
memory buffers inside, supporting the following set of operations:
- Allocate buffer and return handle
- Get buffer from the store with handle
- Put the buffer (last put releases the buffer)
- Map the buffer to the user
This patch contains a generic data structure used to implement the above
memory buffer store interface. Conversion of the existing code to use
the new data structure will follow.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

The default max power is deduced from the card type value in the CPU-CP
info. This value is then set in the max power variable of the device
structure.
Getting the CPU-CP info is done as part of the late init phase
which is called also during reset. This means that a max power value
which is modified via sysfs will be reset during hard reset back to the
default value.
As the max power is updated in any case during device init in
hl_sysfs_init(), this setting in late init can be removed, and the
overriding during reset is thus avoided.

This is another instance of incorrect use of list iterator and
checking it for NULL.
The list iterator value 'map' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty (in this case, the
check 'if (!map) {' will always be false and never exit as expected).
To fix the bug, use a new variable 'iter' as the list iterator,
while use the original variable 'map' as a dedicated pointer to
point to the found element.

This is most likely to happen when the kernel is configured to build a

Detailed description for this pull request:
1. update extcon core driver
- extcon_get_extcon_dev() has been almost used to get the extcon device
on booting time. If extcon provider driver is probed at late time,
the extcon consumer driver get the -EPROBE_DEFER return value.
It requires the inefficient handling code of -EPROBE_DEFER.
Instead, extcon_get_extcon_dev() will return -EPROBE_DEFER
if the required extcon device is none. It makes the extcon consumer driver
to be simplified when getting extcon device.
- Register device after dev_set_drvdata because of accessing
the sysfs attributes at timing of between drv_set_data and device_register.
- Fix some kernel-doc comments of extcon functions.
2. update extcon provider driver
- Update extcon-intel-int3496.c
: Add support for controlling vbus power via regulator and support
to the extcon-intel-int3496.c driver to bind to devices without
an ACPi companion. And fix the minor clean-up.
- Use struct_size() helper on extcon-usbc-cros-ec.c
- Remove the disable irq operation in system sleep for using vbus/id
gpio as the wakeup source on extcon-usb-gpio.c
- Add support of SM5703 device by using existing extcon-sm5502.c
and rename i2c_devic_id from sm5703 to sm5703-muic to reduce confusion
between SM5703 MFD device and extcon device.
- Add usb role class support and add queue work sync before driver release
on extcon-ptn5150.c

MHI Host
--------
Support for new modems:
- Foxconn Cinterion MV32-WA/MV32-WB based on SDX62/SDX65
- Telit FN980 v1 based on SDX55
- Telit FN990 based on SDX65
- Foxconn T99W373/T99W368 based on SDX62/SDX65
Core changes:
- During the recycle of event ring elements, compute the ctxt_wp based on the
local cached value instead of reading from shared memory. This is to prevent
the possible corruption of the ctxt_wp as some of the endpoint devices could
modify the value in shared memory.
- Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
spec allows the host to hard reset the device in the case of an unrecoverable
error and all other reset mechanisms have failed.
- During MHI shutdown, wait for the endpoint device to enter the ready state
post reset before proceeding. This is to avoid a possible race where host
would remove the interrupt handler and device will send ready state
interrupt, resulting in IOMMU fault.
- Bail out updating the MHI register if the read has failed during
read/modify/write.
- Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
register fields in mhi_init_mmio().
MAINTAINERS change:
- Since Qualcomm has moved the email domain for its employess from codeaurora
domain to quicinc, update the same for Hemant.

These interconnects are modeled as clks, not interconnects, therefore
remove the compatibles from the binding as they're unused.

This patch set is to address two clock rate setting issues.
The first patch is to fix a potential cached clock rate mismatching
issue, the issue can lead to the clock rate is missed to be set. Note,
since this potential issue requires specific time window and certain
condition (consumers need to request the same bandwidth) to produce,
the patch is based on analysis but not a real trace log.
The second patch is an extension to cache clock rates for active and
sleep clocks separately, with this change it gives us possibility to set
active and sleep clock with different clock rates.

The Qualcomm interconnect providers started off defining nodes and BCMs
using the DEFINE_QNODE() and DEFINE_QBCM() macros. Unfortunately this
results in a block of long lines that are hard to read, a transition to
explicitly stated definition has been made for newly introduced
platforms.
Transition the SC8180X interconnect provider driver to this style as
well, to make it easier to read while debugging interconnect related
issues.
