9caec6620f clk: tegra210: Fix default rates for HDA clocks
Currently the default clock rates for the HDA and HDA2CODEC_2X clocks
are both 19.2MHz. However, the default rates for these clocks should
actually be 51MHz and 48MHz, respectively. The current clock settings
results in a distorted output during audio playback. Correct the default
clock rates for these clocks by specifying them in the clock init table
for Tegra210.

b3b723d8c4 clk: rockchip: add a type from SGRF-controlled gate clocks
Some clk gates on Rockchip SoCs are part of the SGRF (secure general
register files) and thus only controllable from secure mode, with the
most prominent example being the watchdog.

In most cases we still want to define this as a real clock though,
to have complete clock tree and not reference the generic base-clock
from the devicetree.

So far we've just defined this as factor-1-1 clocks in the clock init,
so define a special clock-type for it so that this definition can be
part of the general tree-definition and save some boilerplate code.

d43628e9bc clk: meson: g12a: Add support for G12B CPUB clocks
Update the Meson G12A Clock driver to support the Amlogic G12B SoC.

G12B clock driver is very close, the main differences are :
- the clock tree is duplicated for the both clusters, and the
  SYS_PLL are swapped between the clusters
- G12B has additional clocks like for CSI an other components

Here only the cpu clock tree is handled.

The code was setting the bit 21 of the CPCCR register to use a divider
of 2 for the "pll half" clock, and clearing the bit to use a divider
of 1.

This is the opposite of how this register field works: a cleared bit
means that the /2 divider is used, and a set bit means that the divider
is 1.

Restore the correct behaviour using the newly introduced .div_table
field.

a9fa2893fc clk: ingenic: Add support for divider tables
Some clocks provided on Ingenic SoCs have dividers, whose hardware value
as written in the register cannot be expressed as an affine function
to the actual divider value.

For instance, for the CPU clock on the JZ4770, the dividers are coded as
follows:

    ------------------
    | Bits     | Div |
    ------------------
    | 0  0  0  |  1  |
    | 0  0  1  |  2  |
    | 0  1  0  |  3  |
    | 0  1  1  |  4  |
    | 1  0  0  |  6  |
    | 1  0  1  |  8  |
    | 1  1  0  | 12  |
    ------------------

To support this setup, we introduce a new field in the
ingenic_cgu_div_info structure that allows to specify the divider table.

3f1f22d800 clk: keystone: sci-clk: extend clock IDs to 32 bits
Currently, the clock identifiers are limited to 255. To support future
SoCs, this muse be extended to 32 bits, which should provide way more
than enough space. Basic support for extending the clock API is going
to be implemented in the firmware driver, but there are some minor
changes that need to be done on the clock driver side first.

8e48b33f9d clk: keystone: sci-clk: probe clocks from DT instead of firmware
Probing all the available clocks from the PM firmware takes quite a lot
of time, increasing boot time. Instead, implement functionality that
parses only the used clocks from DT, and registers these to clock core.
This way, the boot time is greatly improved.

Additionally, provide a Kconfig option for parsing all the clocks from
firmware, if someone requires this. It is mostly useful as a debugging
functionality if we want to inspect the whole clock tree.

a4a4069f45 clk: imx: Add imx_obtain_fixed_clock clk_hw based variant
In order to move to clk_hw based API, imx_obtain_fixed_clock_hw
is added. The end goal here is to have all the clk providers use
the clk_hw based API.

There is no audio_pll2_clk registered, it should be audio_pll2_out.

789bc177f8 clk: bcm: Allow CLK_BCM2835 for ARCH_BRCMSTB
ARCH_BRCMSTB needs to use the BCM2835 clock driver for chips like
BCM7211 which adopted that clock controller, make that possible and the
driver default to be enabled for ARCH_BRCMSTB.

5d59f12a19 clk: bcm: Make BCM2835 clock drivers selectable
Make the BCM2835 clock driver selectable by other
architectures/platforms. ARCH_BRCMSTB will be selecting that driver in
the next commit since new chips like 7211 use the same CPRMAN clock
controller that this driver supports.

4c34282fb7 clk: pwm: implement the .get_duty_cycle callback
Commit 9fba738a53dda2 ("clk: add duty cycle support") added support for
getting and setting the duty cycle of a clock. This implements the
get_duty_cycle callback for PWM based clocks so the duty cycle is shown
in the debugfs output (/sys/kernel/debug/clk/clk_summary).

41b3588dba clk: ti: clkctrl: Fix returning uninitialized data
If we do a clk_get() for a clock that does not exists, we have
_ti_omap4_clkctrl_xlate() return uninitialized data if no match
is found. This can be seen in some cases with SLAB_DEBUG enabled:

Unable to handle kernel paging request at virtual address 5a5a5a5a
...
clk_hw_create_clk.part.33
sysc_notifier_call
notifier_call_chain
blocking_notifier_call_chain
device_add

Let's fix this by setting a found flag only when we find a match.
