In qmi_handle_init(), a buffer is allocated for to hold messages
received through the handle's socket. Any "normal" messages
(expected by the caller) will have a header prepended, so the
buffer size is adjusted to accomodate that.
The buffer must also be of sufficient size to receive control
messages, so the size is increased if necessary to ensure these
will fit.
Unfortunately the calculation is done wrong, making it possible
for the calculated buffer size to be too small to hold a "normal"
message. Specifically, if:
recv_buf_size > sizeof(struct qrtr_ctrl_pkt) - sizeof(struct qmi_header)
AND
recv_buf_size < sizeof(struct qrtr_ctrl_pkt)
the current logic will use sizeof(struct qrtr_ctrl_pkt) as the
receive buffer size, which is not enough to hold the maximum
"normal" message plus its header. Currently this problem occurs
for (13 < recv_buf_size < 20).
This patch corrects this.

If there is at least one entry in the partition table, but no global
entry, the qcom_smem_set_global_partition() should return an error
just like it does if there are no partition table entries.
It turns out the function still returns an error in this case, but
it waits to do so until it has mistakenly treated the last entry in
the table as if it were the global entry found.
Fix the function to return immediately if no global entry is found
in the table.

Two places report an error when a partition header is found to
not contain the right canary value. The error messages do not
properly byte swap the host ids. Fix this, and adjust the format
specificier to match the 16-bit unsigned data type.
Move the error handling for a bad canary value to the end of
qcom_smem_alloc_private(). This avoids some long lines, and
reduces the distraction of handling this unexpected problem.

What phdr_to_last_uncached_entry() returns is the address of the
start of the free space following all allocated uncached entries.
It really doesn't refer to an actual (initialized) private entry
structure. Similarly phdr_to_last_cached_entry() returns the
address of the end of free space, preceding the last allocated cache
entry. Change both functions' return type to be pointer to void
to reflect this.
Meanwhile, phdr_to_first_cached_entry() really *does* point to a
private entry structure, so change its return type to reflect
this fact.

Cached items are found at the high end of an smem partition. A
cached item's shared memory precedes the private entry structure
that describes it.
The address of the structure describing the first cached item should
be returned by phdr_to_first_cached_entry(). However the function
calculates the start address using the wrong structure size.
Fix this by computing the first item's entry structure address by
subtracting the size of a private entry structure rather than a
partition header structure.

This driver deals with memory that is stored in little-endian format.
Update the structures with the proper little-endian types and then
do the proper conversions when reading the fields. Note that we compare
the ids with a memcmp() because we already pad out the string 'id' field
to exactly 8 bytes with the strncpy() onto the stack.

Command DB is a simple database in the shared memory of QCOM SoCs, that
provides information regarding shared resources. Some shared resources
in the SoC have properties that are probed dynamically at boot by the
remote processor. The information pertaining to the SoC and the platform

information using predefined strings.

While doing a global software reset, these bits are not cleared and let

expect the GPHYs in reset, as they aren't during power on.
The asserts were a workaround for a wrong syscon-reboot mask. With a
mask set which includes the GPHY resets, these resets aren't required

MT7622_POWER_DOMAIN_WB doesn't send an ACK when its managed SRAM becomes
stable, which is not like the behavior the other power domains should
have. Therefore, it's necessary for such a power domain to have a fixed
and well-predefined duration to wait until its managed SRAM can be allowed
to access by all functions running on the top.

Instead of adding more and more fields to scp_domain_data which get
checked in the code flow, add a caps field used for an indication the
characteristics for each SCP domain.
At present, type u8 for the caps field is selected which can satisfy the
current situation and doesn't take up extra space against type bool
previously used.

Solve the pd could only ever turn off but never turn them on again,
if the pd registers have the writemask bits.
So far this affects the rk3328 only.

This patch adds support to APR bus (Asynchronous Packet Router) driver.
APR driver is made as a bus driver so that the apr devices can added removed
more dynamically depending on the state of the services on the dsp.
APR is used for communication between application processor and QDSP to
use services on QDSP like Audio and others.

With a later commit an instance of the struct device will be added to
struct genpd and with that the size of the struct tegra_powergate will
be over 1024 bytes. That generates following warning:
drivers/soc/tegra/pmc.c:579:1: warning: the frame size of 1200 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Avoid such warnings by allocating the structure dynamically.

This driver manages the Generic Interface (GENI) firmware based Qualcomm
Universal Peripheral (QUP) Wrapper. GENI based QUP is the next generation
programmable module composed of multiple Serial Engines (SE) and supports
a wide range of serial interfaces like UART, SPI, I2C, I3C, etc. This
driver also enables managing the serial interface independent aspects of
Serial Engines.

Platform device core assumes the ownership of dev.platform_data as
well as that it is dynamically allocated and it will try to kfree it
as a part of platform_device_release(). Change the code to use
platform_device_add_data() instead of a pointer to a static memory to
avoid causing a BUG() when calling platform_device_put().
The problem can be reproduced by artificially enabling the error path
of platform_device_add() call (around line 452).

The problem can be reproduced by artificially enabling the error path

Note that this change also allows us to constify imx7_pgc_domains,
since we no longer need to be able to modify it.

Hwqueue has collect statistics in heavy use queue_pop/queu_push functions
for cache efficiency and make push/pop faster use percpu variables.
For performance reasons, driver should keep descriptor in software handler
as short as possible and quickly return it back to hardware queue.
Descriptors coming into driver from hardware after pop and return back
by push to reduce descriptor lifetime in driver collect statistics on percpu.

This patch provide APIs to allow client drivers to support
probe deferral. On K2G SoC, devices can be probed only
after the ti_sci_pm_domains driver is probed and ready.
As drivers may get probed at different order, any driver
that depends on knav dma and qmss drivers, for example
netcp network driver, needs to defer probe until
knav devices are probed and ready to service. To do this,
add an API to query the device ready status from the knav
dma and qmss devices.

Navigator Subsystem (NAVSS) available on K2G SoC has a cut down
version of QMSS with less number of queues, internal linking ram
with lesser number of buffers etc. It doesn't have status and
explicit push register space as in QMSS available on other K2 SoCs.
So define reg indices specific to QMSS on K2G. This patch introduces
"ti,66ak2g-navss-qm" compatibility to identify QMSS on K2G NAVSS
and to customize the dts handling code. Per Device manual,
descriptors with index less than or equal to regions0_size is in region 0
in the case of K2 QMSS where as for QMSS on K2G, descriptors with index
less than regions0_size is in region 0. So update the size accordingly in
the regions0_size bits of the linking ram size 0 register.
