a38eab52ff drivers: gpu: Move prototype declaration to header file radeon_mode.h
Move prototype declaration of functions radeon_add_atom_connector() and
radeon_add_legacy_connector() to header file drm/radeon/radeon_mode.h
because  they are used by more than one file.

This eliminates the following warning in drm/radeon/radeon_connectors.c:
drivers/gpu/drm/radeon/radeon_connectors.c:1588:1: warning: no previous prototype for ‘radeon_add_atom_connector’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/radeon_connectors.c:2020:1: warning: no previous prototype for ‘radeon_add_legacy_connector’ [-Wmissing-prototypes]

6c7bccea39 drm/radeon/pm: move pm handling into the asic specific code
We need more control over the ordering of dpm init with
respect to the rest of the asic.  Specifically, the SMC
has to be initialized before the rlc and cg/pg.  The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.

This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.

We don't have any userspace interfaces that use HZ as a time unit, so
having our own DRM define is useless.

Remove this remnant from the shared drm core days.

d9906753bb drm: rip out drm_core_has_AGP
Most place actually want to just check for dev->agp (most do, but a
few don't so this fixes a few potential NULL derefs). The only
exception is the agp init code which should check for the AGP driver
feature flag.

6b27f7f0e9 drm/dp: Use AUX constants from specification
The current values seem to be defined in a format that's specific to the
i915, gma500 and radeon drivers. To make this more generally useful, use
the values as defined in the specification.

While at it, prefix the constants with DP_ for improved namespacing.

e4158f1b10 radeon_pm: fix oops in hwmon_attributes_visible() and radeon_hwmon_show_temp_thresh()
Since commit ec39f64bba ("drm/radeon/dpm: Convert to use
devm_hwmon_register_with_groups") radeon_hwmon_init() is using
hwmon_device_register_with_groups(), which sets `rdev' as a device
private driver_data, while hwmon_attributes_visible() and
radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'.

Fix them by using dev_get_drvdata(), in order to avoid this oops:
