Depends on board design, the gpio controlling regulator may
connects with a big capacitance. When need off, it takes some time
to let the regulator to be truly off. If not add enough delay, the
regulator might have always been on, so introduce off-on-delay to
handle such case.

Support three different use cases with rockchip_max98090 driver.
The three use cases:
- max98090 only: Current usage, where HDMI link is missing.
- HDMI only: Needed use case for veyron_mickey board.
- max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.
The presence of max98090 is determined by the presence of
rockchip,audio-codec device property.
The presence of HDMI is determined by the presence of
rockchip,hdmi-codec device property.
Create different sound card based on the configuration.
Note that we keep max98090 only usage for backward compatibility.

Allow codec driver register callback function for plug event.
The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec
dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.
dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.
When connector plug/unplug event happens, report this event using the
callback.
Make sure that audio and drm are using the single source of truth for
connector status.

Tegra210 and prior Tegra chips have deep sleep entry and wakeup related
timings which are platform specific that should be configured before
entering into deep sleep.
Below are the timing specific configurations for deep sleep entry and
wakeup.
- Core rail power-on stabilization timer
- OSC clock stabilization timer after SOC rail power is stabilized.
- Core power off time is the minimum wake delay to keep the system
in deep sleep state irrespective of any quick wake event.
These values depends on the discharge time of regulators and turn OFF
time of the PMIC to allow the complete system to finish entering into
deep sleep state.
These values vary based on the platform design and are specified
through the device tree.
This patch has implementation to configure these timings which are must
to have for proper deep sleep and wakeup operations.

This patch adds suspend and resume pm ops for cpufreq driver.
PLLP is the safe clock source for CPU during system suspend and
resume as PLLP rate is below the CPU Fmax at Vmin.
CPUFreq driver suspend switches the CPU clock source to PLLP and
disables the DFLL clock.
During system resume, warmboot code powers up the CPU with PLLP
clock source. So CPUFreq driver resume enabled DFLL clock and
switches CPU back to DFLL clock source.

Commit 7d79aa8628 ("drm/vboxvideo: Replace struct vram_framebuffer

But since the vboxvideo driver needs the generic dirty tracking code,
it's drm_mode_config_funcs.fb_create should be set to
drm_gem_fb_create_with_dirty not drm_gem_fb_create.
This commit fixes this, fixing the framebuffer not always updating.

The design of the OA unit has been split into several units. We now
have a global unit (OAG) and a render specific unit (OAR). This leads
to some changes on how we program things. Some details :
OAR:
- has its own set of counter registers, they are per-context
saved/restored
- counters are not written to the circular OA buffer
- a snapshot of the counters can be acquired with
MI_RECORD_PERF_COUNT, or a single counter can be read with
MI_STORE_REGISTER_MEM.
OAG:
- has global counters that increment across context switches
- counters are written into the circular OA buffer (if requested)
v2: Fix checkpatch warnings on code style (Lucas)
v3: (Umesh)
- Update register from which tail, status and head are read
- Update logic to sample context reports
- Update whitelist mux and b counter regs
v4: Fix a bug when updating context image for new contexts (Umesh)
v5: Squash patch enabling save/restore of counters into context image
We want this so we can preempt performance queries and keep the
system responsive even when long running queries are ongoing. We
avoid doing it for all contexts.
- use LRI to modify context control (Chris)
- use MASKED_FIELD to program just the masked bits (Chris)
- disable save/restore of counters on cleanup (Chris)
v6: Do not use implicit parameters (Chris)
