Maxim Max77620 has one 32KHz clock output and the clock HW
IP used on this PMIC is same as what it is there in the MAX77686.Add clock driver support for MAX77620 on the MAX77686 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.Signed-off-by: Laxman Dewangan

Pull clk updates from Stephen Boyd:
"It's the usual big pile of driver updates and additions, but we do
have a couple core changes in here as well.Core:
- CLK_IS_CRITICAL support has been added. This should allow drivers
to properly express that a certain clk should stay on even if their
prepare/enable count drops to 0 (and in turn the parents of these
clks should stay enabled).- A clk registration API has been added, clk_hw_register(), and an OF
clk provider API has been added, of_clk_add_hw_provider(). These
APIs have been put in place to further split clk providers from clk
consumers, with the goal being to have clk providers never deal
with struct clk pointers at all. Conversion of provider drivers is
on going. clkdev has also gained support for registering clk_hw
pointers directly so we can convert drivers that don't use
devicetree.New Drivers:
- Marvell ap806 and cp110 system controllers (with clks inside!)
- Hisilicon Hi3519 clock and reset controller
- Axis ARTPEC-6 clock controllers
- Oxford Semiconductor OXNAS clock controllers
- AXS10X I2S PLL
- Rockchip RK3399 clock and reset controllerUpdates:
- MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos
542x SoCs, and some more clk ID exporting for bus frequency scaling
- Proper BCM2835 PCM clk support and various other clks
- i.MX clk updates for i.MX6SX, i.MX7, and VF610

Currently the decision whether to build the renesas-cpg-mssr and
clk-mstp drivers is handled by Makefile logic. However, the rcar-sysc
driver will need to know whether CPG/MSSR and/or CPG/MSTP support are
available or not.To avoid having to duplicate this logic, move it to Kconfig. Provide
non-visible CLK_RENESAS_CPG_MSSR and CLK_RENESAS_CPG_MSTP Kconfig
symbols, which can be used by both Makefiles and C code.Signed-off-by: Geert Uytterhoeven

Pull ARM SoC driver updates from Olof Johansson:
"As we've enabled multiplatform kernels on ARM, and greatly done away
with the contents under arch/arm/mach-*, there's still need for
SoC-related drivers to go somewhere.Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
communicate with power management blocks on these SoCs for use by
clock, regulator and bus frequency drivers.- Allwinner Reduced Serial Bus driver, again used to communicate with
PMICs.- Drivers for ARM's SCPI (System Control Processor). Not to be
confused with PSCI (Power State Coordination Interface). SCPI is
used to communicate with the assistant embedded cores doing power
management, and we have yet to see how many of them will implement
this for their hardware vs abstracting in other ways (or not at all
like in the past).- To make confusion between SCPI and PSCI more likely, this release
also includes an update of PSCI to interface version 1.0.- Rockchip support for power domains.

clk: tegra: Changes for v4.2-rc1
This contains the EMC clock driver that's been exhaustively reviewed and
tested. It also includes a change to the clock core that allows a clock
provider to perform low-level reparenting of clocks. This is required by
the EMC clock driver because the reparenting needs to be done at a very
specific point in time during the EMC frequency switch.

This driver supports the TI CDCE925 programmable clock synthesizer.
The chip contains two PLLs with spread-spectrum clocking support and
five output dividers. The driver only supports the following setup,
and uses a fixed setting for the output muxes:
Y1 is derived from the input clock
Y2 and Y3 derive from PLL1
Y4 and Y5 derive from PLL2
Given a target output frequency, the driver will set the PLL and
divider to best approximate the desired output.Signed-off-by: Mike Looijmans

Add clock drivers for hi6220 SoC, this driver controls the SoC
registers to supply different clocks to different IPs in the SoC.We add one divider clock for hi6220 because the divider in hi6220
also has a mask bit but it doesnot obey the rule defined by flag
"CLK_DIVIDER_HIWORD_MASK", we can not get index of the mask bit by
left shift fixed bits (e.g. 16 bits), so we add this divider clock
to handle it.Signed-off-by: Jorge Ramirez-Ortiz

Having this Kconfig sourced outside the clk menu means the option
is under the "Device Drivers" menu instead of the "Common Clock
Framework" menu. Move it so that the bcm clock config options are
in the right place.Cc: Alex Elder

The EMC clock driver uses symbols exported by the EMC driver, so it
needs the corresponding dependency to avoid build breakage.Signed-off-by: Thierry Reding
