[ Upstream commit ff2e4bfd16 ]
bnxt_re currently uses the names "bnxt_qplib_creq" and "bnxt_qplib_nq-0"
while registering IRQs. There is no way to distinguish the IRQs of
different device ports when there are multiple IB devices registered.
This could make the scenarios worse where one want to pin IRQs of a device
port to certain CPUs.
Fixed the code to use unique names which has PCI BDF information while
registering interrupts like: "bnxt_re-nq-0@pci:0000:65:00.0" and
"bnxt_re-creq@pci:0000:65:00.1".

[ Upstream commit ab112ee789 ]
When the ulp hook to start the IRQ fails because the rings are not
available, tasklets are not enabled. In this case when the driver is
unloaded, driver calls CREQ tasklet_kill. This causes an indefinite hang
as the tasklet is not enabled.
Driver shouldn't call tasklet_kill if it is not enabled. So using the
creq->requested and nq->requested flags to identify if both tasklets/irqs
are registered. Checking this flag while scheduling the tasklet from
ISR. Also, added a cleanup for disabling tasklet, in case request_irq
fails during start_irq.
Check for return value for bnxt_qplib_rcfw_start_irq and in case the
bnxt_qplib_rcfw_start_irq fails, return bnxt_re_start_irq without
attempting to start NQ IRQs.

In the unlikely event that something goes wrong with the device and
its registers, the fan_from_reg() function may return 0. This value
will cause a division-by-zero error in the show_pwm() function.
To prevent this, test the value of
fan_from_reg(data->fan_full_speed[nr]) against 0 before performing
the division. If the division-by-zero error is avoided, assign 0 to
the val variable.

PSCI is not implemented on SparX-5 at all, there is no ATF and U-boot that
is shipped does not implement it as well.
I have tried flashing the latest BSP 2022.12 U-boot which did not work.
After contacting Microchip, they confirmed that there is no ATF for the
SoC nor PSCI implementation which is unfortunate in 2023.
So, disable PSCI as otherwise kernel crashes as soon as it tries probing
PSCI with, and the crash is only visible if earlycon is used.
Since PSCI is not implemented, switch core bringup to use spin-tables
which are implemented in the vendor U-boot and actually work.
Tested on PCB134 with eMMC (VSC5640EV).

In the function sun4i_tcon_init_clocks(), tcon->clk and tcon->sclk0 are
not disabled in the error handling, which affects the release of
these variable. Although sun4i_tcon_bind(), which calls
sun4i_tcon_init_clocks(), use sun4i_tcon_free_clocks to disable the
variables mentioned, but the error handling branch of
sun4i_tcon_init_clocks() ignores the required disable process.
To fix this issue, use the devm_clk_get_enabled to automatically
balance enable and disabled calls. As original implementation use
sun4i_tcon_free_clocks() to disable clk explicitly, we delete the
related calls and error handling that are no longer needed.

Always enable HS video mode setting the TXMD bit, without this change no
video output is present with DSI sinks that are setting
MIPI_DSI_MODE_LPM flag (tested with LT8912B DSI-HDMI bridge).
Previously the driver was enabling HS mode only when the DSI sink was
not explicitly setting the MIPI_DSI_MODE_LPM, however this is not
correct.
The MIPI_DSI_MODE_LPM is supposed to indicate that the sink is willing
to receive data in low power mode, however clearing the
TC358768_DSI_CONTROL_TXMD bit will make the TC358768 send video in
LP mode that is not the intended behavior.

[Why]
The bit for flip addr is being set causing the determination for
FAST vs MEDIUM to always return MEDIUM when plane info is provided
as a surface update. This causes extreme stuttering for the typical
atomic update path on Linux.
[How]
Don't use update_flags->raw for determining FAST vs MEDIUM. It's too
fragile to changes like this.
Explicitly specify the update type per update flag instead. It's not
as clever as checking the bits itself but at least it's correct.

then pull again after the initial validation of the basic header.
