- Some of the APIs are not available on stable kernel. Use kstable specific APIs with LINUX_KERNEL macro condition. - Temporarily comment functions that are not available on Kstable. - Next chip headers are renamed to accommodate more than one next chip. Update next chip includes in init.c and driver.c files. - Rename TEGRA_SOC_HWPM_IP_INACTIVE to TEGRA_HWPM_IP_INACTIVE to follow other macro/enum naming convention. - Use is_resource_active() HAL instead of chip specific function. - Create clock reset functions that will allow us to handle change in APIs on kstable.
