This SoC has some leftover code all over the kernel but no boards are
supported anymore. Remove support for da830 from the davinci clock
driver. With it: remove the ifdefs around the data structures as the
da850 remains the only davinci SoC supported and the only user of this
driver.

Convert the TI clkctrl clock device tree binding to json-schema.
Specify the creator of the original binding as a maintainer.
reg property is used mostly with one item, in am3xxx also with
an arbitrary number of items, so divert from the original binding
specifying two (probably meaning one address and one size).
The consumer part of the example is left out because the full consumer
node would be needed.

We have a lot of driver code that prints an error message when

The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.
This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.

On the MediaTek platform, some SMI LARBs are directly connected to
the SMI Common, while others are connected to the SMI Sub-Common,
which in turn is connected to the SMI Common. The hardware block
diagram can be described as follows.

On the MediaTek MT8188 SoC platform, we encountered power-off failures
and SMI bus hang issues during camera stress tests. The issue arises
because bus glitches are sometimes produced when MTCMOS powers on or
off. While this is fairly normal, the software must handle these
glitches to avoid mistaking them for transaction signals. What's
more, this issue emerged only after the initial upstreaming of this
binding. Without these patches, the SMI becomes unstable during camera
stress tests.
The software solutions can be summarized as follows:
1. Use CLAMP to disable the SMI sub-common port after turning off the
LARB CG and before turning off the LARB MTCMOS.
2. Use CLAMP to disable/enable the SMI sub-common port.
3. Implement an AXI reset for SMI LARBs.
This patch add '#reset-cells' for the clock controller located in image,
camera and IPE subsystems.

of_clk_get_hw_from_clkspec() checks all available clock-providers by
comparing their of nodes to the one from the clkspec. If no matching
clock provider is found, the function returns -EPROBE_DEFER to cause a
re-check at a later date. If a matching clock provider is found, an
authoritative answer can be retrieved from it whether the clock exists
or not.
This does not take into account that the clock-provider may never
appear, because it's node is disabled. This can happen when a clock is
optional, provided by a separate block which never gets enabled.
One example of this happening is the rk3588's VOP, which has optional
additional display clocks coming from PLLs inside the hdmiphy blocks.
These can be used for better rates, but the system will also work
without them.
The problem around that is described in the followups to[1]. As we
already know the of node of the presumed clock provider, add a check via
of_device_is_available() whether this is a "valid" device node. This
prevents eternal defer loops.

On the RZ/G3S SoC, the CPU PLL settings can be set and retrieved through
the CPG_PLL1_CLK1 and CPG_PLL1_CLK2 registers. However, these settings
are applied only when CPG_PLL1_SETTING.SEL_PLL1 is set to 0.
Otherwise, the CPU PLL operates at the default frequency of 1.1 GHz.
Hence add support to the PLL driver for returning the 1.1 GHz frequency
when the CPU PLL is configured with the default frequency.
