Create and register set and get operating point sysfs functions. The operating point notification will contain the requested operating point. The nvcap resource manager will extract the operating point from the notfication and send it to rce via the hsp command interface. In turn, rce will apply the operating point by adjusting the functional clock frequencies for the following camera ip: - rce hardware - vi hardware - isp hardware - nvcsi Jira CAMERASW-26378 Signed-off-by: Robert Kelly <rkelly@nvidia.com> Change-Id: Ia814b2716d3738efb3cbc37307a267140b555f42 Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3179593 (cherry picked from commit d259727a57ecf4b9463030b3418715891b3b1209) Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3189078 Reviewed-by: Semi Malinen <smalinen@nvidia.com> Reviewed-by: Frank Chen <frankc@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com>
