Hey Dave,

In drm_mode_std(), the return value of drm_gtf_mode(),
drm_gtf_mode() and drm_cvt_mode() is assigned to mode,
which will lead to a NULL pointer dereference on failure

Add support for the MIPS firmware processor, used in the Series AXE GPU.
The MIPS firmware processor uses a separate MMU to the rest of the GPU, so
this patch adds support for that as well.
Changes since v6:
- Fix integer overflow in VM map error path
Changes since v5:
- Use alloc_page() when
This adds the basic skeleton of the driver. The driver registers
itself with DRM on probe. Ioctl handlers are currently implemented
as stubs.
Changes since v5:
- Update compatible string & description to match marketing name
- Checkpatch fixes in to/from_pvr_device/file macros
Changes since v3:
Add the device tree binding documentation for the IMG AXE GPU used in
TI AM62 SoCs.

Changes since v6:
- Remove unused gpu
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
- Don't prepare clocks on resource acquisition
- Drop
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:
-
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

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}
Firmware trace is exposed at /sys/debug/dri//pvr_fw/trace_0.

This patch series adds the initial DRM driver for Imagination Technologies
PowerVR
GPUs, starting with those based on our Rogue architecture. It's worth pointing
out that this is a new driver, written from the ground up, rather than a
refactored version of our existing downstream driver
