The sandbox pinmux driver is used in the non-test devicetree as well as
the test one. I didn't realize this when I modified the driver for
tests, and so broke the regular use case (which only resulted in
warnings). First, making the pinmux and the UART group available
pre-relocation to avoid ENODEV errors. Then, convert the pin groups and
functions to the new style, adding onewire group as well.

ENOSYS should only be used when a subsystem is completely absent.
Convert its use in pinctrl-generic to ENOENT, which better reflects the
error condition (that a function/group/pin is missing).

This is an initial series that have all the initial trivial
fixes required for usage of OF_UPSTREAM for the mediatek SoC
This also contains the pcie-gen3 driver and the required tphy
support driver to make it work.
Subsequent series will follow with conversion of the mtk-clk
to permit usage of OF_UPSTREAM and upstream clk ID.
MT7981, MT7986 and MT7988 migration to upstream clock ID
is complete and working on MT7623.

Linux kernel Documentation/devicetree/bindings/gpio/gpio.txt define the
format of the gpio-ranges prop as:
The format is: <[pin controller phandle], [GPIO controller offset],
[pin controller offset], [number of pins]>;
Example:
gpio-ranges = <&foo 0 20 10>, <&bar 10 50 20>;
This means:
- pins 20..29 on pin controller "foo" is mapped to GPIO line 0..9 and
- pins 50..69 on pin controller "bar" is mapped to GPIO line 10..29
For this example, a call to pinctrl_gpio_get_pinctrl_and_offset() using
offset 10 incorrectly return pin controller "foo" instead of "bar".
Fix this by using an exclusive range check.

Support is added for 5 new Qualcomm SoCs:
* QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2
respectively. SM6115 is also used in some mid-range smartphones/tablets.
Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship
smartphones. The board can boot to a U-Boot prompt, but is missing regulators
necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024
respectively. Found on many high end smartphones.
In addition:
* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.
* RB2 gets a work-around to fix the USB dr_mode property before booting Linux.

Currently, IPQ4019 pinctrl driver supports only a very limited number of
pin functions and is not fully DT compatible with Linux pinctrl nodes.
IPQ40xx SoC-s sometimes use different pin function numbers for the same
function depending on the pin number, so for example I2C0 on GPIO58 uses
function number 3 while on GPIO59 it uses function number 2.
So, in order to make the driver compatible with upstream DTS to avoid the
need to patch the pinctrl nodes in U-Boot and support all of the missing
pin functions lets rework the driver based on upstream Linux IPQ4019
pinctrl driver and the pending SM8150 U-Boot pinctrl driver which also uses
different function numbers pased on the exact pin number.

If compiled with logging and debug UART support, the following is printed:
serial_msm serial@78af000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
This is due to the fact that IPQ4019 pinctrl driver is not available prior
to relocation and thus MSM serial will fail probing as pinctrl provider is
not available.
So, lets enable DM_FLAG_PRE_RELOC for IPQ4019 pinctrl to fix this.

This patch is the preparation for SM8150 support. This new SoC
depending on the particular pin can have different numbers for the
same function. For example "rgmii" function for GPIO4 has id=2 while
for GPIO59 it has id=1. So, to support this type of SoCs,
get_function_mux() callback needs to know for which pin the function
is requested.

Pinconfig nodes normally bind recursively with PINCTRL_FULL and
PINCONF_RECURSIVE enabled. However, during U-Boot proper pre-relocation
any node marked with e.g. bootph-all will not bind unless its parent is
also marked for pre-reloc.
group1 {
pinconf1 {
bootph-all;
};
};
This cause the following warning message to be shown during U-Boot
proper pre-reloc stage on Rockchip devices, e.g on RK3568:
ns16550_serial serial@fe660000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
and on RK3328:
ns16550_serial serial@ff130000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
Check pinconfig nodes pre-reloc status recursively to fix this and to
make pinconfig_post_bind work same at both U-Boot proper pre-reloc and
at TPL/SPL stage.
