e0dd79cd43 gpu: nvgpu: rearch mc reset and enable hals
Remove current mc hals
- mc.reset()
- mc.enable()
- mc.disable()
- mc.reset_mask()
- mc.reset_engine()
- mc.reset_engine_enable()

Add new mc hals
- mc.enable_units(g, units, enable)
  > enable/disable given unit(s)
- mc.enable_dev(g, dev, enable)
  > enable/disable engine represented by given device pointer
- mc.enable_devtype(g, devtype)
  > enable/disable all engines of given devtype

Move common mc intr functions to common/mc/mc_intr.c.
Add below common mc functions
- nvgpu_mc_reset_units(g, units)
  > reset given logical OR of nvgpu unit bitmap
- nvgpu_mc_reset_dev(g, dev)
  > reset given single engine via dev
  > if engine is graphics, reset gpcs for nvgpu_next
- nvgpu_mc_reset_devtype(g, devtype)
  > reset all engines of given devtype
  > if devtype is graphics, reset gpcs for nvgpu_next

Cleanup issues with traceability for common.mc:
- Move these declarations under macros or @cond as they are either
  non-fusa or private functions to the unit:
  - gm20b_mc_is_enabled
  - mc_gp10b_log_pending_intrs
  - mc_gp10b_ltc_isr
  - gv11b_mc_is_intr_hub_pending
- Fix typo in SWUTS for gv11b_mc_is_stall_and_eng_intr_pending

a8c9c800cd gpu: nvgpu: reorganization of MC interrupts control
Previously, unit interrupt enabling/disabling and corresponding MC level
interrupt enabling/disabling was not done at the same time.
With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.

For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.

b26acdeb87 gpu: nvgpu: move mc_boot_0 function to hals and rename to get_chip_details
This function gets the GPU chip architecture, implementation and
revision information by reading the MC boot register, hence it
is more suited to be located in HAL files.
test_check_gpu_state is now being run after test_hal_init as the
gops.mc needs to be initialized for test_check_gpu_state subtest.

209f68be3c gpu: nvgpu: fix MISRA errors in nvgpu.hal.mc
Rule 8.6 requires each identifier with external linkage to have exactly
one external definitions.
Rule 10.x necessitates operands to have essential type; left and right
operands should be of same width and type.
Rule 17.7 requires function return value to be checked for error
information.
This patch fixes above mentioned errors in nvgpu.hal.mc.

7a7ae31a26 gpu: nvgpu: pmu_gk20a.c multiple H/W headers include cleanup
pmu_gk20a.c includes hw_mc_gk20a.h other than hw_pwr_gk20a.h
to access & configure pmu interrupt, this breaks single hw header
for HAL file.

Moved PMU interrupt enable to MC unit by creating/modifying current
mc ops intr_unit_config to intr_pmu_unit_config to configure PMU
interrupt specifically as this ops is only used by PMU unit
