panic() in case of error. The panic message repeats the one used by

because of summer time holidays/vacations. The biggest change in the diffstat
is in the Qualcomm clk driver, where they got support for CPUs and handful of
SoCs. After that, the at91 driver got a major rewrite for newer DT bindings
that should make things easier going forward and the TI code moved to a
clockdomain based design. The long tail is mostly small driver updates for
newer clks and some simpler SoC clock drivers such as the Hisilicon and imx
support.
In the core framework, we only have two small changes this time. One is a new
clk API to get all clks for a device with the bulk clk APIs. This allows
drivers that don't care about doing anything besides turning on all the clks to
just clk_get() them all and turn them on. The other change is the beginning of
a way to support save and restore of clk settings in the clk framework. TI is
the only user right now, but we will want to expand upon this design in the
future to support more save and restore of clk registers. At least this gets
us started and works well enough for one SoC, but there's more work in the
future.

When a memblock allocation APIs are called with align = 0, the alignment
is implicitly set to SMP_CACHE_BYTES.
Implicit alignment is done deep in the memblock allocator and it can
come as a surprise. Not that such an alignment would be wrong even
when used incorrectly but it is better to be explicit for the sake of
clarity and the prinicple of the least surprise.
Replace all such uses of memblock APIs with the 'align' parameter
explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment
in the memblock internal allocation functions.
For the case when memblock APIs are used via helper functions, e.g. like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where
appropriate.
The direct memblock APIs users were updated using the semantic patch below:

Currently, TI clock driver uses an encapsulated struct that is cast into
a void pointer to store all register addresses. This can be considered
as rather nasty hackery, and prevents from expanding the register
address field also. Instead, replace all the code to use proper struct
in place for this, which contains all the previously used data.

From Tero Kristo:
"This pull request contains the TI clock driver set to move the
clock implementations under clock driver. Some small portions of
the clock driver code still remain under mach-omap2 after this,
it should be decided whether this code is now obsolete and should
be deleted or should someone try to fix it."
Slight merge conflicts with determine_rate prototype changes.
This clock provider uses the consumer API, so include clk.h
explicitly.

With most of the clock code under clock driver already, the low-level
register access code, and the init code for the same, is no longer
needed outside the clock driver. Thus, these can be moved under clock
driver also.

We should avoid exporting data from drivers, instead use an API for
registering the clock low level operations.

This is no longer used outside clock driver, so move it under the driver
and remove the export for it from the global header file.

As most of the clock driver support code is going to be moved under
drivers/clk/ti, an API for setting / getting the SoC specific clock
features is needed. This patch provides this API and changes the
existing code to use it.

There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

ti_dt_clk_init_provider() can now be used to initialize the contents of
a single clock IP block. This parses all the clocks under the IP block
and calls the corresponding init function for them.
This patch also introduces a helper function for the TI clock drivers
to get register info from DT and append the master IP info to this.

Some devices require their clocks to be available with a specific
dev-id con-id mapping. With DT, the clocks can be found by default
only with their name, or alternatively through the device node of
the consumer. With drivers, that don't support DT fully yet, add
mechanism to register specific clock names.
