[C31][DTS] fix ethernet delays
The current ethernet configuration sets delays in both MAC and PHY. This requires to alter the drivers to allow forcing both delays, which is unnecessary.
This commit sets mode to rgmii-id and sets internal delays to tx=2.75ns and rx=1.75ns. How these values were calculated: the RK3399 gmac is capable of a ~5ns delay. The rx_delay and tx_delay properties can have values 0-100, so one step is ~0.05ns.
The new values have been tested using iperf3 (0 retr in both rx and tx).

[C31][DTS][OVERLAYS] add new overlays for every output-vop combination
Every video output (HDMI, LVDS, eDP, DP over USB TypeC) can be connected to each of the 2 videoport of RK3399, vopB (big) capabe of 4K resolution and vopL (little) only capable of 1080p. We enumerate those configurations in order to genrate every possible video output option.

[ALL][SPI FLASH] Add support for QSPI SST SST26VF032B
Based on commit 980615ac from linux-seco-imx: https://git.seco.com/edgehog/bsp/nxp/linux-seco-imx/-/commit/980615accab64a17b97faa28f889b4a7cf928c75
Add support for the SST26VF032B SPI EEPROM

[C31][DTS] add overlay for SPI rtc

[C31] [DTS] vbus_typec: Remove regulator-always-on property
Type-C port's regulator should not have always-on property to get possibility of being enabled/disabled depending on type of the attachment (device or host). In this case CC controller (fusb302) should be the only consumer of this regulator, otherwise it won't be disabled/enabled when necessary. So change the name of regulator from vbus to vbus_typec, otherwise it would be taken also by rockchip-usb2phy device, as it is looking for a vbus regulator as well. for the usb2phy device in otg mode, in case to control typec port it makes sence to get this regulator in some other way.

[C31] [DTS] Add watchdog device tree configuration for TPS3851
Add watchdog device node to bind with the gpio-wdt driver
--
[DEFCONFIG] Enable GPIO_WATCHDOG support
Enable GPIO_WATCHDOG_ARCH_INITCALL to raise initcall level to arch_initcall, necessary for SBC-C31.
SBC-C31 has TPS3851 voltage supervisor with integrated watchdog. GPIO_WATCHDOG is sufficient to have basic watchdog functionality and manage its pin (WDI), once watchdog is enabled in U-boot using pin (SET1).
--
[Kconfig] PCIE_DW_ROCKCHIP: Add dependency on RFKILL_RK
Being dependent on RFKILL_RK, the pcie-dw-rockchip driver should not be brought into the build without RFKILL_RK.
To avoid linker errors when building without RFKILL_RK enabled: pcie-dw-rockchip.c:2263: undefined reference to `rfkill_get_wifi_power_state'
--
[C31] [DTS] Add configuration for USB Type-C controller FUSB302
Standard Type-C connector supports following configurations:
- USB 3.0 port
- OTG port
- Display port Currently only USB 3.0 (data role - host, power role - source) is supported, due to lack of implementations (e.g. typec mux registration) and mismatches (phy-rockchip-typec driver still needs the deprecated extcon API, e.g. in function tcphy_get_mode). The connector and port nodes retain all the necessary default properties, some of which are currently unused, but kept, some refactoring should probably be done once the drivers have full support.
--
[C31] [DTS] Add alias for PCAL6416 GPIO expander node
When using kernel device tree in U-Boot to have appropriate sequence number for gpio bank added by pcal6416 GPIO expander, because aliases 0 to 4 are already assigned to other gpio banks. In case if gpio expander is probed first, it receives sequence number 0.
This will fix warning "seq 0 is in use by gpio@20".
--
[DRIVERS] mcp251xfd: Add Loopback CAN operation mode support

--
[C31] [DTS] Add CAN over SPI support configuration
Add device tree overlays for CAN devices to be used along the environment setup of the peripheral devices at boot time.
--
[DRIVERS] Add backlight driver for MPS MP3385
Add PWM based backlight driver for MPS MP3385 WLED Controller with I2C Interface.
Initialization values can be passed to the driver via module parameter "settings" from command line or via DTS parameter.
Example command line portion is "mp3385_bl.settings=0xF0,0x44,0x3B,0x03,0x7F,0xE7". The same setting in DTS can be obtained by passing the reg-val: "reg-val = <0xF0 0x44 0x3B 0x03 0x7F 0xE7>;"

[C31] [DTS] Add WiFi and Bluetooth suport configuration
Add configuration needed to support wireless adapter based on Marvell 8997 chipset using SDIO interface. Note: Actual configuration supports NXP Wi-Fi driver for module 88w8997/8987 built as an external module sourced from https://github.com/nxp-imx/mwifiex
Add this module to build with Yocto, using this configuration example in machine config:
KERNEL_MODULE_AUTOLOAD += "mlan moal" KERNEL_MODULE_PROBECONF += "moal" module_conf_moal = "options moal fw_name=mrvl/sdsd8997_combo_v4.bin cal_data_cfg=mrvl/cal_data.conf drv_mode=1 cfg80211_wext=0xf sta_name=wlan wfd_name=p2p max_vir_bss=1 auto_ds=2 ps_mode=2"

[DEFCONFIG] Enable PWRSEQ_SD8787
Enable this power sequence driver which now supports Marvell chipset SD8997 WiFi+BT
--
[DRIVERS] pwrseq_sd8787: Add power sequence support for Marvell SD8997 chipset
Instead of the pwrseq_simple driver which has only reset gpio in the power sequence, the pwrseq_sd8787 driver also adds powerdown gpio to handle in the power sequence.
But the Marvell SD8997 chipset does not have a gpio reset line in the power sequence, only a powerdown one, and to apply the proper power sequence, in this driver added device data to match the appropriate device and therefore to get the correct resources to manage in power sequence.

Move the regulator for LCD power in the overlay file, Add regulator-min(max)-microvolt values to the vcc_sys regulator node used as vin-supply for backlight power supply regulator. Delete property pinctrl for HPD from edp node, as it is not in design and pin is used for HDMI CEC. Delete property does not work from overlay, so use it from base dts.

[C31] [DTS] Assign parent clock to dclk_source
When RK3399_TWO_PLL_FOR_VOP defined that is needed for dual display support, where two PLLs are required, dclk_vop0 exclusively occupies the CPLL, and dclk_vop1 exclusively occupies the VPLL.
Add include rk3399-vop-clk-set.dtsi indirectly by creating seco-rk3399-vop-clk-set.dtsi, because we have to overwrite PLL_NPLL clock frequency to obtain 125MHz clock rate for GMAC.

[C31] [DTS] ramoops: Fix the issue of lack of reserved memory resource

[C31] [DTS] dmc: Add supported DDR frequencies
from boot log: dmc: Get wrong frequency, Request 800000000, Current 856000000 dmc: could not find power_model node dmc: dev_pm_opp_set_rate: failed to find current OPP for freq 856000000 (-34) dmc: Get wrong frequency, Request 200000000, Current 856000000
from DDR training log: ddr_set_rate to 328MHZ ddr_set_rate to 666MHZ ddr_set_rate to 416MHZ, ctl_index 0 ddr_set_rate to 856MHZ, ctl_index 1 support 416 856 328 666 MHz, current 856MHz
In dmc_opp_table node disable operating point nodes with unsupported frequency and add opp nodes for supported 328 416 666 856 MHZ frequencies In dmc node change the frequencies for different system statuses (scenario). The values are taken from reference board with similar LPDDR4 memory. Set auto-freq-en to 0, so disable load frequency scaling function and enable scenario frequency scaling.
Scenario frequency scaling means: entered the specified scenario, DDR frequency will change to the corresponding frequency defined by SYS_STATUS_XXX. The vop-bw-dmc-freq values are valid when load frequency scaling enabled (auto-freq-en=1).
