44f22a5d67 clk: si5351: Convert __clk_get_name() to clk_hw_get_name()
This driver uses __clk_get_name() when it's dealing with struct
clk_hw pointers. Use the simpler form so that we can get rid of
the clk member in struct clk_hw one day.

62f4771198 clk: versatile: Switch to assigned clock parents
We're removing struct clk from the clk provider API. This code is
calling the consumer APIs to change the parent to a 1 MHz fixed
rate clock for each of the clocks that the driver provides. Move
to using the assigned-clock-parents DT property for this instead.
Because this is an ABI break, detect if the property is missing
and fall back to setting the parent explicitly before the clocks
are registered.

e6500344ed clk: track the orphan status of clocks and their children
While children of orphan clocks are not carried in the orphan-list itself,
they're nevertheless orphans in their own right as they also don't have an
input-rate available. To ease tracking if a clock is an orphan or has an
orphan in its parent path introduce an orphan field into struct clk and
update it and the fields in child-clocks when a clock gets added or removed
from the orphan-list.

and was not using clock-indices but some private masks that were pretty
much equivalent.

Move this code in a new driver that handles all the gates array and solves
both these issues.

f04b486d34 clk: shmobile: rz: Add CPG/MSTP Clock Domain support
Add Clock Domain support to the RZ Clock Pulse Generator (CPG) 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.

b93028c9af clk: pxa: pxa3xx: fix CKEN register access
Clocks 0 to 31 are on CKENA, and not CKENB. The clock register names
were inadequately inverted. As a consequence, all clock operations were
happening on CKENB, because almost all but 2 clocks are on CKENA.

As the clocks were activated by the bootloader in the former tests, it
escaped the testing that the wrong clock gate was manipulated. The error
was revealed by changing the pxa3xx-nand driver to a module, where upon
unloading, the wrong clock was disabled in CKENB.
