Add a new type of clocks that can be provided to a peripheral.
In addition to the peripheral clock, this new clock that can use several
input clocks as parents can generate divided rates.
This would allow a peripheral to have finer grained clocks for generating
a baud rate, clocking an asynchronous part or having more
options in frequency.Signed-off-by: Nicolas Ferre

Pull ARM SoC driver updates from Olof Johansson:
"Some releases this branch is nearly empty, others we have more stuff.
It tends to gather drivers that need SoC modification or dependencies
such that they have to (also) go in through our tree.For this release, we have merged in part of the reset controller tree
(with handshake that the parts we have merged in will remain stable),
as well as dependencies on a few clock branches.In general, new items here are:
- Qualcomm driver for SMM/SMD, which is how they communicate with the
coprocessors on (some) of their platforms- memory controller work for ARM's PL172 memory controller
- reset drivers for various platforms
- PMU power domain support for Marvell platforms
- Tegra support for T132/T210 SoCs: PMC, fuse, memory controller

Add Clock Domain support to the Clock Pulse Generator (CPG) Module Stop
(MSTP) Clocks driver using the generic PM Domain. This allows to
power-manage the module clocks of SoC devices that are part of the
CPG/MSTP Clock Domain using Runtime PM, or for system suspend/resume.SoC devices that are part of the CPG/MSTP Clock Domain and can be
power-managed through an MSTP clock should be tagged in DT with a
proper "power-domains" property.The CPG/MSTP Clock Domain code will scan such devices for clocks that
are suitable for power-managing the device, by looking for a clock that
is compatible with "renesas,cpg-mstp-clocks".Signed-off-by: Geert Uytterhoeven

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are using
it. Also add in a clkdev.h include that was missing in a file
using clkdev APIs.Cc: Peter De Schrijver

Clock driver requires access to some CM API functions once the code
is being moved under the clock driver from the platform directory.
Gate type clock requires access to cm_wait_module_ready and
cm_split_idlest_reg functions, which are both used for waiting until
the module being clocked has been successfully activated. These CM
APIs are now exported through the ti_clk_ll_ops struct.Signed-off-by: Tero Kristo

tegra_clocks_apply_init_table() needs to be called after the udelay
loop has been calibrated (see commit
441f199a37cfd66c5dd8dd45490bd3ea6971117d ("clk: tegra: defer
application of init table") for why that is). On existing Tegra SoCs
this was done by calling tegra_clocks_apply_init_table() from
tegra_dt_init(). To make this also work on ARM64, we need to change
this into an initcall. tegra_dt_init() is called from
customize_machine which is an arch_initcall. Therefore this should
also work on existing 32bit Tegra SoCs.Tested on Tegra20 (ventana), Tegra30 (beaverboard), Tegra124 (jetson TK1) and
Tegra132.Signed-off-by: Peter De Schrijver

Introduces omap3 legacy clock data under clock driver. The clock data
is also in new format, which makes it possible to get rid of the
clk-private.h header. This patch also introduces SoC specific init
functions that shall be called from the low level init.The data format used in this file has two possible evolution paths;
it can either be removed completely once no longer needed, or it will
be possible to retain the format and modify the TI clock driver to be
a loadable module at some point. The actual path to be followed
will be decided later.Signed-off-by: Tero Kristo
