The mlx5 driver dumps the entire CQE buffer by default for few syndromes.
Some syndromes are expected due to the application behavior [ex:
MLX5_CQE_SYNDROME_REMOTE_ACCESS_ERR, MLX5_CQE_SYNDROME_REMOTE_OP_ERR and
MLX5_CQE_SYNDROME_LOCAL_PROT_ERR]. Hence, for these syndromes, the patch
converts the log level from KERN_WARNING to KERN_DEBUG. This enables the
application to get the CQE buffer dump by changing to KERN_DEBUG level
as and when needed.

The return value is wrong in ext4_load_and_init_journal(). The local
variable 'err' need to be initialized before goto out. The original code
in __ext4_fill_super() is fine because it has two return values 'ret'
and 'err' and 'ret' is initialized as -EINVAL. After we factor out
ext4_load_and_init_journal(), this code is broken. So fix it by directly
returning -EINVAL in the error handler path.

USB controllers on SM8250 doesn't work after coming back from suspend.
This can be fixed by keeping the USB GDSCs in retention mode so that
hardware can keep them ON and put into rentention mode once the parent
domain goes to a low power state.

The function platform_get_irq prints an error message into the kernel
log when the irq isn't found.
Since the interrupt is actually optional and not provided by some SoCs,
use platform_get_irq_optional which does not print an error message.

Use one-based indexing throughout the file for BLSP devices to avoid
confusion. Most of the node names and labels are consistent already.
This patch just fixes a few pinconf node names to match the one-based

On Qualcomm SC7180 and SM8450 SocS, the typical debug console serial
port is part of GENI Serial Engine QUP Wrapper Controller which uses
interconnects. This means that without interconnect drivers, the serial
might not probe. Without serial console, the root might not be mounted
by initramfs:
+ REASON=No init found. Try passing init= bootarg. PS1=(initramfs
...
(initramfs) run-init -c /dev/console -n /root /sbin/init
run-init: opening console: No such file or directory
This means that interconnect drivers on these Qualcomm SoCs cannot be
modules and must be built-in to mount rootfs.

DT schema expects TLMM pin configuration nodes to be named with
'-state' suffix and their optional children with '-pins' suffix.
Merge subnodes named 'pinconf' and 'pinmux' into one entry, add function
where missing (required by bindings for GPIOs) and reorganize overriding
pins by boards.
Split the SPI and UART configuration into separate nodes
1. SPI (MOSI, MISO, SCLK), SPI chip-select, SPI chip-select via GPIO,
2. UART per each pin: TX, RX and optional CTS/RTS.
This allows each board to customize them easily without adding any new
nodes.

This reverts commit e440e30e26 because it
is not a reliable way of fixing SPI CS glitch and it depends on specific
Linux kernel pin controller driver behavior.
This behavior of kernel driver was changed in commit b991f8c362
("pinctrl: core: Handling pinmux and pinconf separately") thus
effectively the DTS fix stopped being effective.
Proper solution for the glitching SPI chip select must be implemented in
the drivers, not via ordering of entries in DTS, and is already
introduced in commit d21f4b7ffc ("pinctrl: qcom: Avoid glitching lines
when we first mux to output").

The Trogdor Homestar DTSI adds additional GPIO52 pin to secondary I2S pins
("sec_mi2s_active") and configures it to "mi2s_1" function.
The Trogdor DTSI (which is included by Homestar) configures drive
strength and bias for all "sec_mi2s_active" pins, thus the intention was
to apply this configuration also to GPIO52 on Homestar.
