The J721S2 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive ADAS applications and
industrial applications requiring AI at the network edge. This SoC extends
the Jacinto 7 family of SoCs with focus on lowering system costs and power
while providing interfaces, memory architecture and compute performance for
single and multi-sensor applications.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep capable
dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA), C7x
floating point Vector DSP.
* 3D GPU: Automotive grade IMG BXS-4-64
* Vision Processing Accelerator (VPAC) with image signal processor and
Depth and Motion Processing Accelerator (DMPAC)
* Two CSI2.0 4L RX plus one eDP/DP, two DSI Tx, and one DPI interface.
* Two Ethernet ports with RGMII support.
* Single 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role device subsystems,
* Up to 20 MCANs, 5 McASP, eMMC and SD, OSPI/HyperBus memory controller,
QSPI, I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Hardware accelerator blocks containing AES/DES/SHA/MD5 called SA2UL
management.
* Chips and Media Wave521CL H.264/H.265 encode/decode engine

Use transport specific transmission timeout (max_rx_timeout_ms) also for
polling transactions.
Initially when polling mode was added, it was intended to be used only
in scheduler context and hence the choice of 100us for the polling timeout.
However the only user for that was dropped for other SCMI concurrency
issues, so it shouldn't cause any issue to increase this timeout value now.

====================
Add new helpers to access traced function arguments that
came out of the trampoline batch changes [1].
Get n-th argument of the traced function:
long bpf_get_func_arg(void *ctx, u32 n, u64 *value)
Get return value of the traced function:
long bpf_get_func_ret(void *ctx, u64 *value)
Get arguments count of the traced funtion:
long bpf_get_func_arg_cnt(void *ctx)
v2 changes:
- added acks
- updated stack diagram
- return -EOPNOTSUPP instead of -EINVAL in bpf_get_func_ret
- removed gpl_only for all helpers
- added verifier fix to allow proper arguments checks,
Andrii asked for checking also 'int *b' argument in
bpf_modify_return_test programs and it turned out that it's currently
not supported by verifier - we can't read argument that is int pointer,
so I had to add verifier change to allow that + adding verifier selftest
- checking all arguments in bpf_modify_return_test test programs
- moved helpers proto gets in tracing_prog_func_proto with attach type check

The trampoline now stores number of arguments on ctx-8
address, so it's easy to verify argument index and find
return value argument's position.
Moving function ip address on the trampoline stack behind
the number of functions arguments, so it's now stored on
ctx-16 address if it's needed.

Adding support to access arguments with int pointer arguments
in tracing programs.
Currently we allow tracing programs to access only pointers to
string (char pointer), void pointers and pointers to structs.
If we try to access argument which is pointer to int, verifier
will fail to load the program with;
R1 type=ctx expected=fp
; int BPF_PROG(fmod_ret_test, int _a, __u64 _b, int _ret)
0: (bf) r6 = r1
; int BPF_PROG(fmod_ret_test, int _a, __u64 _b, int _ret)
1: (79) r9 = *(u64 *)(r6 +8)
func 'bpf_modify_return_test' arg1 type INT is not a struct
There is no harm for the program to access int pointer argument.
We are already doing that for string pointer, which is pointer
to int with 1 byte size.
Changing the is_string_ptr to generic integer check and renaming
it to btf_type_is_int.

Samsung J5 2015 is a MSM8916 based Smartphone. It is similar to some of the
other MSM8916 devices, especially the Samsung ones.
With this patch initial support for the following is added:
- eMMC/SD card
- Buttons
- USB (although no suiting MUIC driver currently)
- UART (untested for lack of equipment)
- WiFi/Bluetooth (WCNSS)
It is worth noting that Samsung J5 with MSM8916 exists in different
generations (e.g Samsung J5 2015 and Samsung J5 2016) which each have
different models (e.g. samsung-j5nlte, samsung-j5xnlte, etc). This patch
is only regarding the 2015 generation, but should work with all of it's
models, as far as we could test.

When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

Without the bound checks for scpi_pd->name, it could result in the buffer
overflow when copying the SCPI device name from the corresponding device
tree node as the name string is set at maximum size of 30.
Let us fix it by using devm_kasprintf so that the string buffer is
allocated dynamically.

Stefan Wahren says:
====================
add Vertexcom MSE102x support
This patch series adds support for the Vertexcom MSE102x Homeplug GreenPHY
chips [1]. They can be connected either via RGMII, RMII or SPI to a host CPU.
These patches handles only the last one, with an Ethernet over SPI protocol
driver.
The code has been tested only on Raspberry Pi boards, but should work
on other platforms.
Changes in V3:
- drop IF_PORT_HOMEPLUG again, since it's actually not used
Changes in V2:
- improve lock handling for RX & TX path
- add new patch to introduce IF_PORT_HOMEPLUG as suggested by Andrew Lunn
- address all the comments by Jakub Kicinski, Andrew Lunn, Kernel test robot

Commit 8633ef82f1 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") made the Generic System Framebuffers (sysfb) driver able
to be built on non-x86 architectures.
But it left the efifb_setup_from_dmi() function prototype declaration in
the architecture specific headers. This could lead to the following
compiler warning as reported by the kernel test robot:
drivers/firmware/efi/sysfb_efi.c:70:6: warning: no previous prototype for function 'efifb_setup_from_dmi' [-Wmissing-prototypes]
void efifb_setup_from_dmi(struct screen_info *si, const char *opt)
^
