This patch moves the API host1x_job_submit to job.c file. It also adds a new API host1x_job_complete. This is in preparation to add runtime PM support to host1x & its modules. The idea is to call pm_runtime_get from host1x_job_submit and pm_runtime_put from host1x_job_complete. This way the runtime PM calls are localized to single file & easy to maintain as well as debug Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> --- drivers/gpu/host1x/cdma.c | 2 ++ drivers/gpu/host1x/channel.c | 8 -------- drivers/gpu/host1x/channel.h | 1 - drivers/gpu/host1x/job.c | 12 ++++++++++++ drivers/gpu/host1x/job.h | 3 +++ 5 files changed, 17 insertions(+), 9 deletions(-)
