bf802f5d54 power: extend prefix match to regulator-name property
This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

0b189b6ce1 Revert "sandbox: remove os_putc() and os_puts()"
While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.

For ease of debugging it seems better to revert this change.

This reverts commit 47b98ad0f6.

Convert the sandbox architecture to make use of the new asm-generic/io.h

non-identity mapping between physical & virtual addresses we can't
simply make use of the generic mapping functions, but are able to

ee87a097b0 dm: test: replace dm_scan_dt() by of dm_extended_scan_fdt() in dm_do_test
This allows to scan the DT including all "clocks" node's sub-nodes
in which fixed-clock are defined.
All fixed-clock should be defined inside a clocks node which collect all
external oscillators. Until now, all clocks sub-nodes can't be binded except
if the "simple-bus" compatible string is added which is a hack.

Update test.dts by moving clk_fixed node inside clocks.

e2bc87d41c sandbox: Fix comparison of unsigned enum expression warning
In os_dirent_get_typename() we are checking that type falls within the
known values of the enum os_dirent_t.  With clang-3.8 testing this value
as being >= 0 results in a warning as it will always be true.  This
assumes of course that we are only given valid data.  Given that we want
to sanity check the input, we change this to check that it falls within
the range of the first to the last entry in the given enum.

e48eeb9ea3 dm: blk: Improve block device claiming
The intention with block devices is that the device number (devnum field
in its descriptor) matches the alias of its parent device. For example,
with:

	aliases {
		mmc0 = "/sdhci@700b0600";
		mmc1 = "/sdhci@700b0400";
	}

we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.

Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.

To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.

Add a test to verify the behaviour.

Spin-Table/PSCI.
