Smart PC Solutions Builder allows for OEM to define a large number of
custom system states to dynamically switch to. The system states are
referred to as policies, and multiple policies can be loaded onto the
system at any given time, however only one policy can be active at a
given time.

These definitions are used fro qemu, and qemu imports this marco in the

msm is automagically upgrading normal commits to full modesets, and
that's a big no-no:
- for one this results in full on->off->on transitions on all these
crtc, at least if you're using the usual helpers. Which seems to be
the case, and is breaking uapi
- further even if the ctm change

Linus series proposed to break out ili9882t as separate driver,
but he didn't have time for that extensive rework of the driver.
As discussed by Linus and Doug [1], keep macro using the "struct panel_init_cmd"
until we get some resolution about the binary size issue.
[1]:
The Starry ILI9882t-based panel should never have been part of the boe
tv101wum driver, it is clearly based on the Ilitek ILI9882t display
controller and if you look at the custom command sequences for the
panel these clearly contain the signature Ilitek page switch (0xff)
commands. The hardware
At present, we have found that there may be a problem of blurred
screen during fast sleep/resume. The direct cause of the blurred
screen is that the IC does not receive 0x28/0x10. Because of the
particularity of the IC, before the panel enters sleep hid must
stop scanning, i2c_hid_core_suspend
Add the UAPI implementation for the PowerVR driver.
Changes from v6
- Add padding to struct drm_pvr_dev_query_gpu_info
- Improve BYPASS_CACHE flag documentation
- Add SUBMIT_JOB_FRAG_CMD_DISABLE_PIXELMERGE flag
Changes from v4:
- Remove CREATE_ZEROED flag for BO creation (all buffers are now
Implement job submission ioctl. Job scheduling is implemented using
drm_sched.
Jobs are submitted in a stream format. This is intended to allow the UAPI
data format to be independent of the actual FWIF structures in use, which
vary depending on the GPU in use.
The stream formats are documented
Add power management to the driver, using runtime pm. The power off
sequence depends on firmware commands which are not implemented in this
patch.
Changes since v5:
- Use RUNTIME_PM_OPS() to declare PM callbacks
- Add Kconfig dependency on CONFIG_PM
Changes since v4:
- Suspend runtime PM before
The infrastructure includes parsing of the firmware image, initialising
FW-side structures, handling the kernel and firmware command
ringbuffers and starting & stopping the firmware processor.
This patch also adds the necessary support code for the META firmware
processor.
Changes since v6:
-
Changes since v5:
- Split up header commit due to size

Implement ioctls to create and destroy free lists and HWRT datasets. Free
lists are used for GPU-side memory allocation during geometry processing.
HWRT datasets are the FW-side structures representing render targets.
Changes since v6:
- Fix out-of-bounds shift in get_cr_multisamplectl_val()
Implement ioctls for the creation and destruction of contexts. Contexts are
used for job submission and each is associated with a particular job type.
Changes since v5:
- Fix context release in final error path in pvr_context_create()
Changes since v3:
- Use drm_dev_{enter,exit}
Add documentation for the UAPI.
Changes since v5:
- Remove obsolete VM documentation

Acquire clock and register resources, and enable/map as appropriate.
Changes since v3:
- Remove regulator resource (not used on supported platform)
- Use devm helpers
- Use devm_clk_get_optional() for optional clocks
