Newbus handles multiple equally named device classes without problems,
so there is no reason to use slightly cryptic "<foo>_shdci" for them.
In contrast, the driver module name must be unique, so "<foo>_shdci"
is the right name for it.
as kernel drivers and their dependency onto mmc(4); this allows for
incrementing the mmc(4) module version but also for entire omission
of these bridge declarations for mmccam(4) in a single place, i. e.

comments, marking unused parameters as such, style(9), whitespace,
etc.
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
- Remove redundant assignments of the default bus_generic_print_child
device method (I've whipped these out of the tree as part of r227843
once, but they keep coming back ...),
- use DEVMETHOD_END,
- use NULL instead of 0 for pointers.
o Trim/adjust includes.
This is required for FDT's standard "reg-io-width" property
(similar to "reg-shift" property) found in many DTS files.
This fixes operation on Altera Arria 10 SOC Development Kit,
where standard ns8250 uart allows 4-byte access only.

- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
By this, any SMP kernel can be compiled with SMP_ON_UP support.
- Enable runtime detection of CPU multiprocessor extensions only
if SMP_ON_UP option is used. In other cases (pure SMP or UP),
statically compile only required variant.
- Don't leak multiprocessor instructions to UP kernel.
- Correctly handle data cache write back to point of unification.
DCCMVAU is supported on all armv7 cpus.
- For SMP_ON_UP kernels, detect proper TTB flags on runtime.

and host1x module. Unfortunately, tegra124 SoC doesn't have 2D acceleration
engine and 3D requires not yet started nouveau driver.
These drivers forms a first non-x86 DRM2 enabled graphic stack.
Note, there are 2 outstanding issues:
- The code uses gross hack in order to be comply with
OBJT_MGTDEVICE pager. (See tegra_bo_init_pager() in tegra_bo.c)
- Due to improper(probably) refcounting in drm_gem_mmap_single()
(in drm_gem.c), the gem objects are never released.
I hope that I will be able to address both issues in finite time,
but I don't want to touch x86 world now.

- EMC clock have standard peripheral clock block. Use it.
- Implement full frequency set method for PLLD2. This PLL
is used as HDMI pixel clock so we must be able to set it
to wide range of frequencies, within 5% tolerance allowed
by HDMI specification. Due to this, full state space search
(over m, n, p fields) is necessary.

- Read interrupt properties at bus enumeration time and store
it into global mapping table.
- At bus_activate_resource() time, given mapping entry is resolved and
connected to real interrupt source. A copy of mapping entry is attached
to given resource.
- At bus_setup_intr() time, mapping entry stored in resource is used
for delivery of requested interrupt configuration.
- For MSI/MSIX interrupts, mapping entry is created within
pci_alloc_msi()/pci_alloc_msix() call.
- For legacy PCI interrupts, mapping entry must be created within
pcib_route_interrupt() by pcib driver itself.
