JIRA DNVGPU-123 Function will copy possible clock points for a given master clock domain to pointer passed. pointer with NULL value and count of zero can be passed to query number of clock points for a given domain so that memory can be allocated and function called again to fill clock points Change-Id: Iec6206f23789980036be99793599e934bd221035 Reviewed-on: http://git-master/r/1218912 (cherry picked from commit 9219697bff1e12deb605325055a02a7b387996e9) Signed-off-by: Vijayakumar <vsubbu@nvidia.com> Reviewed-on: http://git-master/r/1235055 Reviewed-by: Thomas Fleury <tfleury@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
