The previous cleanup of BMC attributes left a few holes, and if
you run with lockdep debugging with a BMC with the proper attributes,
you could get a warning.
This patch removes all the unused attributes from the BMC structure,
since they are all declared in the .data section now. It makes
the attributes all static. It fixes the referencing of the
attributes in a couple of cases that dynamically added the files
depending on BMC information.

Before this commit sunxi_factors_register uses of_iomap(node, 0) to get
the clk registers. The sun6i prcm has factor clocks, for which we want to
use sunxi_factors_register, but of_iomap(node, 0) does not work for the prcm
factor clocks, because the prcm uses the mfd framework, so the registers
are not part of the dt-node, instead they are added to the platform_device,
as platform_device resources.
This commit makes getting the registers the callers duty, so that
sunxi_factors_register can be used with mfd instantiated platform device too.
While at it also add error checking to the of_iomap calls.
This commit also drops the __init function from sunxi_factors_register since
platform driver probe functions are not __init.

The ahb1_sdram clock gate is only used for accessing the sdram
controller's registers over the bus. It is not used for actually clock
the controller or the dram, hence it does not need to be protected.
This also gets rid of the problem when the protected ahb1_sdram gate
is prepared/enabled while it is still an orphan, and the operation
is not propagated to the correct parent.

It seems that ever since (536f6b9 mmc: dw_mmc: Reset DMA before
enabling IDMAC) landed upstream that SD cards have been very unhappy
on rk3288-evb. They were a little unhappy before that change, but
after that change they're REALLY unhappy.
It turns out that the above fix happens to fix a corruption when
reading card information during probe time. Without the fix we didn't
detect that high speed SD cards could actually support high speed.
With the fix we suddenly detect that they're high speed and we try to
use them at 50MHz. That doesn't work so well on EVB with the default
drive strength (maybe because there are two physical SD card slots
hooked up to the same pin?).
Fix the problem by bumping up the drive strength of the sdmmc lines.

When amdkfd and radeon are compiled inside the kernel image (not as modules),
radeon will load before amdkfd, which will cause a bug when radeon will probe
the GPUs.
When the two drivers are compiled as modules, amdkfd is loaded after radeon is
loaded but before radeon starts probing the GPUs. This is done because radeon
loads the amdkfd module through symbol_request function.
This patch makes amdkfd load before radeon when they are both compiled inside
the kernel image, which makes the behavior similar to the case when they are
modules, and prevents the kernel bug.

AMD GPU devices are dependent on AMD IOMMU controller functionality to allow
the GPU to access a process's virtual memory address space, without the need
for pinning the memory.
This patch changes the order in the drivers makefile, so iommu/ subsystem is
linked before gpu/ subsystem. That way, if the gpu and iommu drivers are
compiled inside the kernel image (not as modules), the correct order of device
loading is still maintained (iommu module is loaded before gpu module).

All of mmc controllers include SDMMC, SDIO0, SDIO1, and EMMC on RK3288
are limited to 150Mhz. It was mainly caused by two reasons:
- RK3288's IO pad(except DDR IO pad) is generic, which can only support
the max of 150Mhz.
- Mmc controller was designed at 150Mhz, and the pressure test by IC team
was based on this freequency point.
