i2c: tegra: fix unknown interrupt issue after ARB lost
For i2c transaction with repeat start (We post 7W [header + data
for Write followed by read in FIFO]) and unmask required interrupts.
But HW starts processing if there are atleast 3W in FIFO and during
this time if ARB lost error occurs then current data in FIFO is cleared
and chance of posting remaining data after FIFO is cleared. Now
SW handles the ARB lost error as interrupts are enabled later after
posting all packets and after clearing the ARB lost interrupt the
packet mode is disabled(Normal mode), which causes the Normal mode
interrupt(Unknown interrupt in case of packet mode) due to stale
data in fifo.
- To fix this, enable (unmask) error interrupt before posting the
packets into FIFO and clear the packet mode disable before clearing
ARB lost error also for other errors(NACK/FIFO overflow).
- Dont issue bus clear for ARB lost error if bus is operating in
multimaster mode.

gpu: nvgpu: suppress prints in submit path
When we run out of gpfifo space or private command buffer
space, we have error spew like below :
__gk20a_channel_syncpt_incr: not enough priv cmd buffer space
gk20a_submit_channel_gpfifo: fail
Dumping these prints to UART cause increase in submit
latencies
But on these failures, we return -ENOSPC to UMD and then
UMD retries the submit, hence it might be unnecessary to dump
these prints
Hence, remove the error prints of insufficient space
and use gk20a_dbg_fn() instead of gk20a_err() to print failure
in gk20a_submit_channel_gpfifo()
During a critical thermal trip, orderly_poweroff is called.
However, if the userspace is slow to react to poweroff (systemd),
and the thermal zone is configured with polling mode because of
either polling_delay or passive_delay, thermal_core may end up
in calling orderly_poweroff multiple times.
This eventually slows the userspace even more by
scheduling overwhelming number of threads in the system.
Relevant dump_stack spew during the shutdown process:
dump_backtrace+0x0/0xf4
show_stack+0x14/0x1c
dump_stack+0x20/0x28
handle_critical_trips+0x80/0xa0
handle_thermal_trip+0x40/0x64
thermal_zone_device_update+0xf0/0x110
thermal_zone_device_check+0x10/0x18
process_one_work+0x274/0x430
worker_thread+0x184/0x294
kthread+0xc0/0xc8
We should not try to spawn-off more threads once we have
decided to shutdown i.e. we should disable polling mode
once it is known that a critical trip is going to result
in a poweroff. This patch does that by setting the polling
and passive delay to zero which cancels the repeated work
and allows userspace to shutdown.
