Pull rockchip clk driver updates from Heiko Stuebner:

The biggest addition is probably the special clock-type for ddr clock
control. While reading that clock is done the normal way from the
registers, setting it always requires some sort of special handling
to let the system survive this addition.

As the commit message explains, there are currently 3 handling-types
known. General SRAM-based code on rk3288 and before (which is waiting
essentially for the PIE support that is currently being worked on),
SCPI-based clk setting on the rk3368 through a coprocessor, which we
might support once the support for legacy scpi-variants has matured
and now on the rk3399 (and probably later) using a dcf controller that
is controlled from the arm-trusted-firmware and gets accessed through
firmware calls from the kernel. This is the variant we currently
support, but the clock type is made to support the other variants in
the future as well.

Apart from that slightly bigger chunk, we have a mix of PLL rates,
clock-ids and flags mainly for the rk3399.

And interestingly an iomap fix for the legacy gate driver, where I
hopefully could deter the submitter from actually using that in any
new works.

Changing the rate of the DDR clock needs special care, as the DDR
is of course in use and will react badly if the rate changes under it.

Over time different approaches to handle that were used.

Past SoCs like the rk3288 and before would store some code in SRAM
while the rk3368 used a SCPI variant and let a coprocessor handle that.

New rockchip platforms like the rk3399 have a dcf controller to do ddr
frequency scaling, and support for this controller will be implemented
in the arm-trusted-firmware.

This new clock-type should over time handle all these methods for
handling DDR rate changes, but right now it will concentrate on the
SIP interface used to talk to ARM trusted firmware.

clk: versatile/icst: add Integrator core module clocks

The Integrator/AP and Integrator/CP have special derivatives
of the ICST525 control registers, where some bits have been
hardwired but others are possible to adjust, resulting in a
control register that makes it possible to set an even,
desired megahertz value.

The Integrator/AP and Integrator/CP have slightly different
layout so we support them using different compatible
strings.

After adding these clocks, the Integrator-specific cpufreq
driver can be switched over to use the generic operating
point device tree cpufreq driver.

Instead of simply writing a value to the oscillator control
register we switch to the more elaborate method of providing
a bitmask and use regmap_update_bits() to poke the right bits
for the desired frequency, this is needed since these control
registers sometimes control more than one clock.

document file for maxim,max77802 and move all information to
maxim,max77686 DT binding document.

8 years agoclk: max77686: Combine Maxim max77686 and max77802 driver

clk: max77686: Combine Maxim max77686 and max77802 driver

The clock IP used on the Maxim PMICs max77686 and max77802 are
same. The configuration of clock register is also same except
the number of clocks.

Part of common code utilisation, there is 3 files for these chips
clock driver, one for common and two files for driver registration.

Combine both drivers into single file and move common code into
same common file reduces the 2 files and make max77686 and max77802
clock driver in single fine. This driver does not depends on the
parent driver structure. The regmap handle is acquired through
regmap APIs for the register access.

This combination of driver helps on adding clock driver for different
Maxim PMICs which has similar clock IP like MAX77620 and MAX20024.

clk: fixed-rate: Remove export symbol on setup function

This function is only called by builtin code, but we always
exported it and had marked it as __init before commit
e4eda8e0654c (clk: remove exported function from __init section,
2013-01-06) removed that marking. Given that it isn't used by
modules, lets unexport it and add back __init.
