92be6f7a00 tegra: hwpm: restructure HWPM driver
- Update HWPM driver to add HAL layer. This will allow support for multiple chips.
- Add below data structure hierarchy for HWPM driver
HWPM driver structure -> chip info struct -> ip info array -> perfmux/perfmon info array
NOTE: To make commit message more legible, using "aperture" instead of "perfmux and/or perfmon"
- Chip info structure contains
  - Array of IP info
  - HAL function pointers
- IP info structure contains IP specific info
  - Number of instances
  - Number of apertures per instance
  - Aperture ranges, strides, static info array
  - Aperture dynamic arrays
- Aperture info structure contains
  - Hw index
  - Physical address info
  - MMIO address info
- Add separate IP info files
- Create separate files that include logic for allowlist, memory buffer, resources, ip, regops to make functions more legible.
- Move probe, ioctl and io functions to os/linux path.
- Add fn, info, register and verbose debug log levels to controls debug messages
  - add debugfs node to update dbg_mask
- Correct MGBE perfmux base address

multiple chip support in the future.
Create new specific functions
- Initialize hwpm structures
- Reserve and release PMA and RTR apertures
- Zero, update and check allowlists
- Set and get fake registers for MC aperture on simulation
- perfmon dt aperture enums

c7db51d6df tegra: hwpm: separate ip_map for t234
Move ip_maps specific to t234 to a separate file.
This will allow support for multiple chips.
Add new member index_mask to hwpm_resource_aperture structure. The
index_mask will be used to reserve available IP instances.

579bc23ee6 tegra: hwpm: add support for SOC HWPM <-> IP interface
Add support for IP registering mechanism for runtime
callback and perfmux read/writes.
void tegra_soc_hwpm_ip_register(struct tegra_soc_hwpm_ip_ops *hwpm_ip_ops);

IP's callback are called to disable and enable IP runtime pm.
At this moment, only VIC/NVENC/OFA driver registration is supported.
Also will take-up perfmux register read/write in follow-up patch.

70941decf9 tegra: hwpm: add SOC HWPM driver
Add a driver for programming the Tegra SOC HWPM path. SOC HWPM allows
performance monitoring of various Tegra IPs.

The profiling tests cases are configured through IOCTLs sent by a
userspace profiling app. The IOCTLs provide the following features:
  - IP discovery and reservation
  - Buffer management
  - Whitelist query
  - Register read/write ops
