1cd5018175 clk: meson: axg: add the audio clock controller driver
The axg audio clock controller is the clock generation unit for the
amlogic audio subsystem of A113 based SoCs. It may be clocked by 8
different plls provided by the primary clock controller and also by
10 slave bit clocks and 10 slave sample clocks which may be provided
by external components, such as audio codecs, through the SoC pads.

It contains several muxes, dividers and gates which are fed into the
the different devices of the audio subsystem.

3054a55c5d clk: meson: add axg audio sclk divider driver
Add a driver to control the clock divider found in the sample clock
generator of the axg audio clock controller.

The sclk divider accumulates specific features which make the generic
divider unsuitable to control it:
- zero based divider (div = val + 1), but zero value gates the clock,
  so minimum divider value is 2.
- lrclk variant may adjust the duty cycle depending the divider value
  and the 'hi' value.

e8dd920776 clk: meson: add triple phase clock driver
Add a driver to control the output of the sample clock generator found
in the axg audio clock controller.

The goal of this driver is to coherently control the phase provided to
the different element using the sample clock generator. This simplify
the usage of the sample clock generator a lot, without comprising the
ability of the SoC.

443f228578 clk: meson: clean-up meson clock configuration
Clean the dependencies in meson clock Kconfig.
CLK_AMLOGIC should actually select CLK_REGMAP_MESON which it uses. Also,
each platform should select CLK_AMLOGIC, so everything is properly turned
on when the platform Kconfig enable each configuration flag

9fba738a53 clk: add duty cycle support
Add the possibility to apply and query the clock signal duty cycle ratio.

This is useful when the duty cycle of the clock signal depends on some
other parameters controlled by the clock framework.

For example, the duty cycle of a divider may depends on the raw divider
setting (ratio = N / div) , which is controlled by the CCF. In such case,
going through the pwm framework to control the duty cycle ratio of this
clock would be a burden.

A clock provider is not required to implement the operation to set and get
the duty cycle. If it does not implement .get_duty_cycle(), the ratio is
assumed to be 50%.

This change also adds a new flag, CLK_DUTY_CYCLE_PARENT. This flag should
be used to indicate that a clock, such as gates and muxes, may inherit
the duty cycle ratio of its parent clock. If a clock does not provide a
get_duty_cycle() callback and has CLK_DUTY_CYCLE_PARENT, then the call
will be directly forwarded to its parent clock, if any. For
set_duty_cycle(), the clock should also have CLK_SET_RATE_PARENT for the
call to be forwarded

c987ac6f1f clk: meson-gxbb: set fclk_div2 as CLK_IS_CRITICAL
On Amlogic Meson GXBB & GXL platforms, the SCPI Cortex-M4 Co-Processor
seems to be dependent on the FCLK_DIV2 to be operationnal.

The issue occurred since v4.17-rc1 by freezing the kernel boot when
the 'schedutil' cpufreq governor was selected as default :

  [   12.071837] scpi_protocol scpi: SCP Protocol 0.0 Firmware 0.0.0 version
  domain-0 init dvfs: 4
  [   12.087757] hctosys: unable to open rtc device (rtc0)
  [   12.087907] cfg80211: Loading compiled-in X.509 certificates for regulatory database
  [   12.102241] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'

But when disabling the MMC driver, the boot finished but cpufreq failed to
change the CPU frequency :

  [   12.153045] cpufreq: __target_index: Failed to change cpu frequency: -5

A bisect between v4.16 and v4.16-rc1 gave
05f814402d ("clk: meson: add fdiv clock gates") to be the first bad commit.
This commit added support for the missing clock gates before the fixed PLL
fixed dividers (FCLK_DIVx) and the clock framework basically disabled
all the unused fixed dividers, thus disabled a critical clock path for
the SCPI Co-Processor.

This patch simply sets the FCLK_DIV2 gate as critical to ensure
nobody can disable it.

6a4d4b3253 RISC-V Updates for the 4.18 Merge Window
This tag contains some small RISC-V updates I'd like to target for 4.18.
 They are all fairly small this time.  Here's a short summary, there's
 more info in the commits/merges.
 
 * A fix to __clear_user to respect the passed arguments.
 * Enough support for the perf subsystem to work with RISC-V's ISA
   defined performance counters.
 * Support for sparse and cleanups suggested by it.
 * Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
 * Some MAINTAINERS cleanups.
 * The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
   present.
 
 I've given these a simple build+boot test.
