- Create tegra_hwpm_element_enable() instead of directly using perfmon_enable() HAL. This will allow us to expand tegra_hwpm_element_enable in future. - Update log messages in ip structure init code and floorsweep info function. - It is possible that IP instances and elements to have 0 start range address. So, modify check for available elements to use range end instead. - Use tegra_hwpm_fake_readl() and tegra_hwpm_fake_writel() macros instead of fake_readl() and fake_write() functions. That way we have similar implementation of IO functions and macros can be used across OSes. - Check that reserve perfmon function is invoked only for HWPM components. This check will be useful for expansion in types of components in the future. - Clean up and rearrange tegra_hwpm_regops_readl_impl() and tegra_hwpm_regops_writel_impl() to have designated code corresponding to the element type. - Currently, device open and release functions are incorrectly using clock enable/disable functions instead of using HALs. Correct open and close functions to use lock HALs. - Currently, tegra_hwpm_update_mem_bytes() doesn't validate mem_mgmt structure allocation before accessing mem_bytes_kernel pointer. This can lead to kernel crash. Update tegra_hwpm_update_mem_bytes() to return error if mem_mgmt structure s not allocated.
