7374aec956 clk: scpi: fix return type of __scpi_dvfs_round_rate
The frequencies above the maximum value of signed integer(i.e. 2^31 -1)
will overflow with the current code.

This patch fixes the return type of __scpi_dvfs_round_rate from 'int'
to 'unsigned long'.

80b4ae7ace clk: qoriq: Separate root input clock for core PLLs on ls1012a
ls1012a has separate input root clocks for core PLLs versus the
platform PLL, with the latter described as sysclk in the hw docs.
If a second input clock, named "coreclk", is present, this clock will be
used for the core PLLs.

8e56133e5c clk: at91: fix clk-generated parenting
clk_generated_startup is called after clk_hw_register. So the first call to
get_parent will not have the correct value (i.e. 0) and because this is
cached, it may never be updated.

b90da67543 clk: mvebu: ap806: introduce a new binding
As for cp110, the initial intent when the binding of the ap806 system
controller was to have one flat node. The idea being that what is
currently a clock-only driver in drivers would become a MFD driver,
exposing the clock, GPIO and pinctrl functionality. However, after taking
a step back, this would lead to a messy binding. Indeed, a single node
would be a GPIO controller, clock controller, pinmux controller, and
more.

This patch adopts a more classical solution of a top-level syscon node
with sub-nodes for the individual devices. The main benefit will be to
have each functional block associated to its own sub-node where we can
put its own properties.

The introduction of the Armada 7K/8K is still in the early stage so the
plan is to remove the old binding. However, we don't want to break the
device tree compatibility for the few devices already in the field. For
this we still keep the support of the legacy compatible string with a big
warning in the kernel about updating the device tree.

55de4d06b4 clk: mvebu: ap806: do not depend anymore of the *-clock-output-names
As it was done for the cp110, this patch modifies the way the clock names
are created. The name of each clock is now created by using its physical
address as a prefix (as it was done for the platform device
names). Thanks to this we have an automatic way to compute a unique name.

370d919271 clk: sunxi-ng: sun5i: Fix ahb_bist_clk definition
AHB BIST gate is actually controlled with bit 7.

This bug was detected while trying to use the NAND controller which is
using the DMA engine to transfer data to the NAND.
Since the ahb_bist_clk gate bit conflicts with the ahb_dma_clk gate bit,
the core was disabling the DMA engine clock as part of its 'disable
unused clks' procedure, which was causing all DMA transfers to fail after
this point.

b5a53b61a2 Sort of on the quieter side this time, which is probably due more
to me not catching up as quickly on patch review than anything else.
 Overall it seems normal though, a few small changes to the core, mostly
 small non-critical fixes here and there as well as driver updates for new
 and existing hardware support. The biggest things are the TI clk driver
 rework to lay the groundwork for clkctrl support in the next merge window
 and the AmLogic audio/graphics clk support.
 
 Core:
  * clk_possible_parents debugfs file so we know which parents a clk
    could possibly have
  * Fix to make clk rate change notifiers stop on the first failure instead
    of continuing
 
 New Drivers:
  * Mediatek MT6797 SoCs
  * hi655x PMIC clks
  * AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
  * Allwinner H5 SoCs and PRCM hardware
 
 Updates:
  * Nvidia Tegra T210 cleanups and non-critical fixes
  * TI OMAP cleanups in preparation for clkctrl support
  * Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
  * ZTE zx296718 SoC VGA clks
  * Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
  * Support for IDT VersaClock 5P49V5935

that checkpatch catches it earlier.

3417f3528a clk: ti: divider: try to fix ti_clk_register_divider
Commit 6c0afb5039 ("clk: ti: convert to use proper register
definition for all accesses") converted all register accesses in
the TI clk driver to use a proper struct instead of a void
pointer casted struct that fits into a u32. Unfortunately, it
missed a conversion here in the didivder code, leading to a
compiler warning like so:

drivers/clk/ti/divider.c: In function 'ti_clk_register_divider':
drivers/clk/ti/divider.c:460:8: error: 'reg' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Treating a 'u32' variable as a structure leads to a stack
overflow here, and the register address we pass down is never
initialized. Convert this part of the code as well so things
work properly.

b3da896e2f clk: cs2000: select 12.20 High Accuracy on LFRatioCfg
cs2000 can select Static/Dynamic ratio based Frequency Synthesizer
Mode, it can select 20.12 High Multiplier interpret for 32-bit
User Defined Ratio if Dynamic ratio mode. Otherwise it should select
12.20 High Accuracy mode.
Current cs2000 is supporting Static ratio mode only, so it should
select 12.20 High Accuracy mode, not 20.12 High Multiplier mode.
This patch fixes it.

b295a015cd clk: cs2000: tidyup DEVICE_CFG2 settings
DEVICE_CFG2 can select ratio from user defined ratio and LOCKCLK is
for it. But current driver sets fixed 0 value. This patch fixes it.
Note is that current cs2000 driver is using/supporting only ratio0
(= ch0) now.

DEVICE_CFG2 can select STATIC/DYNAMIC ratio mode, and current cs2000
driver is selecting STATIC mode, but it was not understandable on
current code. This patch also solve this issue.

41ee7caf59 clk: x86: add "mclk" alias for Baytrail/Cherrytrail
Due to timing requirements, TI and Conexant manage the audio
reference clock from their ASoC codec drivers using the "mclk"
string. This patch adds another lookup for the "pmc_plt_clk_3"
clock to avoid Intel-specific tests in those codec drivers and
use code as-is.

To avoid a leak, clk_add_alias() is not used in this patch.
Instead the lookup is created manually as part of the .probe()
step and dropped in the .remove() step.

"pmc_plt_clk_3" is used exclusively for audio on all known
Baytrail/CherryTrail designs and is e.g. routed on the MCLK
(pin 26) of the MinnowBoardMAX Turbot LSE connector.
