The polling rate is already specified in some devicetrees, like
imx8mp.dtsi for example, but was not selected so far. For the
trippoints, the cpu-thermal node is used. Also get the polling rate from
this node. Use the default of 5000ms if the polling rate should not be
specified in the devicetree.
NOTE: The polling rate from the devicetree will be used after this
patch. In imx8*.dtsi devicetrees the polling delay is set to 2000ms for
example.

ADC support is implied by the Rockchip arch Kconfig but that means it
should be possible to disable ADC support and still be able to build.
However the weak implementation of rockchip_dnl_key_pressed() currently
blindly use functions from the ADC subsystem which do not exist when ADC
is not enabled, failing the build.
Therefore, let's encapsulate this logic with a check on the ADC symbol
being selected.

The ADC controller drivers are obviously all depending on ADC symbol

While they don't seem to fail to build without, they won't be useful

The SARADC is used on Jaguar for multiple things:
- channel 0 is used (at runtime) as a BIOS button,
- channel 2 is exposed on the Mezzanine connector for customer specific
logic,
- channel 5 and 6 are used for identification,
Since the SARADC requires a vref-supply provided by the RK806 PMIC, its
support and the support for its regulators are also enabled.
The button, adc, pmic and regulator commands are also enabled for CLI
use in U-Boot for debugging and scripting purposes.
The RK806 PMIC on Jaguar being routed on the SPI bus, let's enable
Rockchip SPI controller driver.
Finally, the SARADC channel 1 on Jaguar is hardwired so will never
change in the lifetime of a unit, for that reason, disable the Rockchip
Download Mode check by setting ROCKCHIP_BOOT_MODE_REG symbol to 0.

This adds support for the SARADCv2 found on RK3588.
There is no stop callback as it is currently configured in single
conversion mode, where the ADC is powered down after a single conversion
has been made.
Due to what seems to be a silicon bug, a controller reset needs to be
issued before starting a channel conversion otherwise Rockchip says that
channel 1 will error whatever that means. This is aligned with upstream
and downstream Linux kernel as well as downstream U-Boot.

This adds support for RK806, only the SPI variant has been tested.
The communication "protocol" over SPI is the following:
- write three bytes:
- 1 byte: [0:3] length of the payload, [6] Enable CRC, [7] Write
- 1 byte: LSB register address
- 1 byte: MSB register address
- write/read length of payload
The CRC is always disabled for now.
The RK806 technically supports I2C as well, and this should be able to
support it without any change, but it wasn't tested.
The DT node name prefix for the buck converters has changed in the
Device Tree and is now dcdc-reg. The logic for buck converters is
however manageable within the current logic inside the rk8xx regulator
driver. The same cannot be said for the NLDO and PLDO.
Because pmic_bind_children() parses the DT nodes and extracts the LDO
index from the DT node name, NLDO and PLDO will have overlapping
indices. Therefore, we need a separate logic from the already-existing
ldo callbacks. Let's reuse as much as possible though.

The read-only mode is currently supported but only for 16b-aligned
buffers. For unaligned buffers, the last byte will be read in RW mode
right now, which isn't what is desired. Instead, let's put the
controller back into RO mode for that last byte and skip any write in
the xfer loop.
This is required for 3-wire SPI mode where PICO/POCI lanes are shorted
on HW level. This incidentally the recommended design for RK806 PMIC for
RK3588 products.

Currently, if the environment is stored on an MMC device, the device
number is hardcoded by CONFIG_SYS_MMC_ENV_DEV. This is problematic
because many boards can choose between booting from an SD card or a
removable eMMC. For example, the Rock64 defconfig sets
CONFIG_SYS_MMC_ENV_DEV=1, which corresponds to the SD card. If an eMMC
is used as the boot device and no SD card is installed, it is impossible
to save the environment.
To avoid this problem, we can choose the environment MMC device based on
the boot device. The theobroma-systems boards already contain code to do
this, so this commit simply moves it to the common Rockchip board file,
with some refactoring. I also removed another implementation of
mmc_get_env_dev() from tinker_rk3288 that performed MMC boot device
detection by reading a bootrom register.
This has been tested on a Rock64v2.

USB gadget is not working fully as expected on RK3328, it uses a
board_usb_init() function to initialize the DWC2 OTG port.
The board_usb_init() function does not intgrate with the generic phy
framework and as a result the USB phy is not properly configured before
or after USB gadget use.
Having both USB_DWC2 and DWC2_OTG enabled for the same board is also
causing some issues.
Trying to use rockusb or ums command after usb stop result in a freeze
due to usb stop is putting the phy in a suspended state.
=> usb start
=> usb stop
=> ums 0 mmc 0
--> freeze due to usb phy is suspended <--
Fix this by only using one of USB_DWC2 (host) or DWC2_OTG (peripheral)
depending on the most likely usage of the otg port and by migrating to
use DM_USB_GADGET instead of a board_usb_init() function.
The nanopi-r2 and orangepi-r1-plus variants share OTG and power using a
Type-C connector, mark these boards dr_mode as peripheral, the most
likely usage is for recovery and image download.
The rock64 and roc-cc currently use dr_mode as host, remove the DWC2_OTG
driver from these boards to ensure that the USB_DWC2 driver is used.
The rock-pi-e board does not enable the usb20_otg node so both USB_DWC2
and DWC2_OTG is removed from this board.
Enable RockUSB and UMS on all boards with a otg port in peripheral mode.
Also with the migration to DM_USB_GADGET completed the U-Boot specific
change to reorder usb nodes in the soc device tree can be reverted.

SPL can safely load U-Boot proper + FDT to [10M, 11.5M) with this layout.

[ -X, 16M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 15M, 16M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
Because bind and probe udevice instanses is allocated on the pre-reloc
malloc heap, there is going to be an overlap when reloc malloc heap
reaches close to 512 KiB of usage.
