Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board.
The Lochnagar can take several input clocks from the host system,
provides several of its own clock sources, and provides extensive
routing options for those clocks to be supplied to the attached
CODEC/Amp device.

We used to have a clock framework that isn't really used these days, except
for a few clocks and/or SoCs. Most of the time, the new framework and
drivers (sunxi-ng) will provide everything needed for the customer devices
to operate properly.
Since we're not needing it that much, it might make sense to disable those
drivers, for example when we want to reduce the kernel size. Let's add
options in Kconfig that can be disabled if needed, but are still on by
default to keep the same features in the standard case.

because of summer time holidays/vacations. The biggest change in the diffstat
is in the Qualcomm clk driver, where they got support for CPUs and handful of
SoCs. After that, the at91 driver got a major rewrite for newer DT bindings
that should make things easier going forward and the TI code moved to a
clockdomain based design. The long tail is mostly small driver updates for
newer clks and some simpler SoC clock drivers such as the Hisilicon and imx
support.
In the core framework, we only have two small changes this time. One is a new
clk API to get all clks for a device with the bulk clk APIs. This allows
drivers that don't care about doing anything besides turning on all the clks to
just clk_get() them all and turn them on. The other change is the beginning of
a way to support save and restore of clk settings in the clk framework. TI is
the only user right now, but we will want to expand upon this design in the
future to support more save and restore of clk registers. At least this gets
us started and works well enough for one SoC, but there's more work in the
future.

This patch adds a driver for MAX9485, a programmable audio clock generator.
The device requires a 27.000 MHz clock input. It can provide a gated
buffered output of its input clock and two gated outputs of a PLL that can
generate one out of 16 discrete frequencies. There is only one PLL however,
so the two gated outputs will always have the same frequency but they can
be switched individually.
The driver for this device exposes 4 clocks in total:
- MAX9485_MCLKOUT: A gated, buffered output of the input clock
- MAX9485_CLKOUT: A PLL that can be configured to 16 different
discrete frequencies
- MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT
Some PLL output frequencies can be achieved with different register
settings. The driver will select the one with lowest jitter in such cases.

for the TI Davinci family of SoCs. So far those clks have been supported
with a custom implementation of the clk API in the arch port instead of in
the CCF. With this driver merged we're one step closer to having a single
clk API implementation.
The other large diff is from the Amlogic clk driver that underwent some
major surgery to use regmap. Beyond that, the biggest hitter is Samsung
which needed some reworks to properly handle clk provider power domains
and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some cleanups
and small fixes for some of the more esoteric features. And the usual
set of driver non-critical fixes, cleanups, and minor additions are here as
well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs

HSDK board manages its clocks using various PLLs. These PLL have same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.
Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.
We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.
As of today we add support for PLLs that generate clock for the
HSDK arc cpus, system, ddr, AXI tunnel and hdmi.
By this patch we add support for several plls (arc cpus pll and others),
so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll
and regular probing for others plls.

Add driver for IDT VersaClock 5 5P49V5923 and 5P49V5933 chips. These
chips have two clock inputs, XTAL or CLK, which are muxed into single
PLL/VCO input. In case of 5P49V5923, the XTAL in built into the chip
while the 5P49V5923 requires external XTAL.
The PLL feeds two fractional dividers. Each fractional divider feeds
output mux, which allows selecting between clock from the fractional
divider itself or from output mux on output N-1. In case of output
mux 0, the output N-1 is instead connected to the output from the mux
feeding the PLL.
The driver thus far supports only the 5P49V5923 and 5P49V5933, while
it should be easily extensible to the whole 5P49V59xx family of chips
as they are all pretty similar.

Part of common code utilisation, there is 3 files for these chips
