[media] exynos-gsc: Add support for Exynos5433 specific version

2016-11-16T18:37:24+00:00

This patch adds support for Exynos5433 specific version of the GScaler module. The main difference between Exynos 5433 and earlier is addition of new clocks that have to be controlled.

[media] exynos-gsc: Simplify system PM even more

2016-11-16T18:34:21+00:00

System PM callbacks only ensure that device is runtime suspended/resumed, so remove them and use generic pm_runtime_force_suspend/resume helper.

[media] exynos-gsc: Simplify system PM

2016-11-16T18:33:52+00:00

It's not needed to keep a local flag about the current system PM state. Let's just remove that code and the corresponding debug print.

[media] exynos-gsc: Do full clock gating at runtime PM suspend

2016-11-16T18:33:09+00:00

To potentially save more power in runtime PM suspend state, let's also prepare/unprepare the clock from the runtime PM callbacks.

[media] exynos-gsc: Fixup clock management at ->remove()

2016-11-16T18:32:17+00:00

To make sure the clock is fully gated in ->remove(), we first need to to bring the device into full power by invoking pm_runtime_get_sync(). Then, let's both unprepare and disable the clock.

[media] exynos-gsc: Make PM callbacks available conditionally

2016-11-16T18:31:54+00:00

There are no need to set up the PM callbacks (runtime and system) unless they are being used. It also causes compiler warnings about unused functions. Silence the warnings by making them available for CONFIG_PM (runtime callbacks) and CONFIG_PM_SLEEP (system sleep callbacks).

[media] exynos-gsc: Make driver functional when CONFIG_PM is unset

2016-11-16T18:31:24+00:00

The driver depended on CONFIG_PM to be functional. Let's remove that dependency, by enable the runtime PM resourses during ->probe() and update the device's runtime PM status to reflect this.
