possibly less?). Note that the later bifrost GPUs follow the standard
64-bit stage 1 format.
The differences in the format compared to 64-bit stage 1 format are:
The 3rd level page entry bits are 0x1 instead of 0x3 for page entries.
The access flags are not read-only and unprivileged, but read and write.
This is similar to stage 2 entries, but the memory attributes field matches
stage 1 being an index.
The nG bit is not set by the vendor driver. This one didn't seem to matter,
but we'll keep it aligned to the vendor driver.

drm/meson: Add G12A Video Clock setup
While switching to the Common Clock Framework is still Work In Progress,
this patch adds the corresponding G12A HDMI PLL setup to be on-par
with the other SoCs support.
The G12A has only a single tweak about the high frequency setup,
where the HDMI PLL needs a specific setup to handle correctly the
5.94GHz DCO frequency.
Apart that, it handls ecorrectly all the other HDMI frequencies
and can achieve even better DMT clock frequency precision with
the larger fractional dividier width.

drm/cirrus: rewrite and modernize driver.
Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by roughly 70% I think it'll still be alot easier to review than a
longish baby-step patch series.
Changes summary:
- Given the small amout of video memory (4 MB) the cirrus device has
the rewritten driver doesn't try to manage buffers there. Instead
it will blit (memcpy) the active framebuffer to video memory.
- All gem objects are stored in main memory and are manged using the
new shmem helpers. ttm is out.
- It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24
or RG16 at blit time if needed, to avoid the pitch becoming larger
than what the cirrus hardware can handle.
- The simple display pipeline is used.
- The generic fbdev emulation is used.
- It's a atomic driver now.
- It runs wayland.

drm/lima: driver for ARM Mali4xx GPUs
- Mali 4xx GPUs have two kinds of processors GP and PP. GP is for
OpenGL vertex shader processing and PP is for fragment shader
processing. Each processor has its own MMU so prcessors work in
virtual address space.
- There's only one GP but multiple PP (max 4 for mali 400 and 8
for mali 450) in the same mali 4xx GPU. All PPs are grouped
togather to handle a single fragment shader task divided by
FB output tiled pixels. Mali 400 user space driver is
responsible for assign target tiled pixels to each PP, but mali
450 has a HW module called DLBU to dynamically balance each
PP's load.
- User space driver allocate buffer object and map into GPU
virtual address space, upload command stream and draw data with
CPU mmap of the buffer object, then submit task to GP/PP with
a register frame indicating where is the command stream and misc
settings.
- There's no command stream validation/relocation due to each user
process has its own GPU virtual address space. GP/PP's MMU switch
virtual address space before running two tasks from different
user process. Error or evil user space code just get MMU fault
or GP/PP error IRQ, then the HW/SW will be recovered.
- Use GEM+shmem for MM. Currently just alloc and pin memory when
gem object creation. GPU vm map of the buffer is also done in
the alloc stage in kernel space. We may delay the memory
allocation and real GPU vm map to command submission stage in the
furture as improvement.
- Use drm_sched for GPU task schedule. Each OpenGL context should
have a lima context object in the kernel to distinguish tasks
from different user. drm_sched gets task from each lima context
in a fair way.

drm: shmem: Off by one in drm_gem_shmem_fault()
The shmem->pages[] array has "num_pages" elements so the > should be >=
to prevent reading beyond the end of the array. The shmem->pages[]
array is allocated in drm_gem_shmem_prime_import_sg_table().
Fixes: 2194a63a818d ("drm: Add library for shmem backed GEM objects")

drm/vc4: Use drm_print_regset32() for our debug register dumping.
This removes a bunch of duplicated boilerplate for the debugfs vs

drm: Add a helper function for printing a debugfs_regset32.
The debugfs_regset32 is nice to use for reducing boilerplate in
dumping a bunch of regs in debugfs, but we also want to be able to
print to dmesg them at runtime for driver debugging. drm_printer lets
us format debugfs and the printk the same way.
v2: Add some kerneldoc for the function (requested by danvet)

drm/v3d: Rename the fence signaled from IRQs to "irq_fence".
We have another thing called the "done fence" that tracks when the

confusing.

drm/komeda: Add irq handling
1. Added irq_handler/irq_enable/irq_disable to komeda_dev_func, then the
Komeda-CORE can control the HW irq via these chip function.
2. Install irq and register irq_handler to system by DRM, so once the IRQ
coming, the handling sequence is:
komeda_kms_irq_handler(int irq, void *data)
/* step 1. call into the CHIP to recognize event */
mdev->funcs->irq_handler(mdev, &evts);
/* step 2. notify the crtc to handle the events */
for (i = 0; i < kms->n_crtcs; i++)
komeda_crtc_handle_event(&kms->crtcs[i], &evts);
v2:
- Move get IRQ number into this change.
- Enable irq before drm_dev_register.
