ARM: dts: stm32: Add DH Electronics DHCOM SoM and PDK2 board Add support for DH Electronics DHCOM SoM and PDK2 rev. 400 carrier board. This is an SoM with STM32MP15xx and an evaluation kit. The baseboard provides Ethernet, UART, USB, CAN and optional display.

ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1 This commit manages diversity for STM32M15x SOCs with: - dedicated files to support all STM32MP15 SOCs family. The differences between those SOCs are: -STM32MP151 [1]: common file. -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU. -STM32MP157 [3]: STM32MP153 + DSI + GPU. - new files to manage security diversity on STM32MP15x SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot. -Y = C means cryp IP + secure boot. - stm32mp157 pinctrl files to better manage package diversity.

The DFU usage procedure is identical to STM32MP1 DHCOR SoM, see commit 3919aa1722a ("ARM: dts: stm32: Add DFU support for DHCOR recovery") , except for switching the SoM into DFU mode. By default, the DHCOM SoM has no dedicated mechanism for setting BOOTn straps into UART/USB mode, therefore to enter DFU mode, the SoC must fail to boot from boot media which can be selected by the BOOTn strap override mechanism first and then fall back to DFU mode. In case of a SoM with pre-populated BOOTn strap override button, power the system off, remove microSD card (if applicable), hold down the BOOTn strap override button located between eMMC and SoM edge connector, power on the SoM. The SoC will fail to boot from SD card and fall back into DFU mode.

ARM: dts: stm32: Switch DWMAC RMII clock to MCO2 on DHCOM The DHCOM SoM has two options for supplying ETHRX clock to the DWMAC block and PHY. Either (1) ETHCK_K generates 50 MHz clock on ETH_CLK pad for the PHY and the same 50 MHz clock are fed back to ETHRX via internal eth_clk_fb clock connection OR (2) ETH_CLK is not used at all, MCO2 generates 50 MHz clock on MCO2 output pad for the PHY and the same MCO2 clock are fed back into ETHRX via ETH_RX_CLK input pad using external pad-to-pad connection. Option (1) has two downsides. ETHCK_K is supplied directly from either PLL3_Q or PLL4_P, hence the PLL output is limited to exactly 50 MHz and since the same PLL output is also used to supply SDMMC blocks, the performance of SD and eMMC access is affected. The second downside is that using this option, the EMI of the SoM is higher. Option (2) solves both of those problems, so implement it here. In this case, the PLL4_P is no longer limited and can be operated faster, at 100 MHz, which improves SDMMC performance (read performance is improved from ~41 MiB/s to ~57 MiB/s with dd if=/dev/mmcblk1 of=/dev/null bs=64M count=1). The EMI interference also decreases.

ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1 This commit manages diversity for STM32M15x SOCs with: - dedicated files to support all STM32MP15 SOCs family. The differences between those SOCs are: -STM32MP151 [1]: common file. -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU. -STM32MP157 [3]: STM32MP153 + DSI + GPU. - new files to manage security diversity on STM32MP15x SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot. -Y = C means cryp IP + secure boot. - stm32mp157 pinctrl files to better manage package diversity.

ARM: dts: stm32: Add DFU support for DHCOM recovery This patch configures U-Boot SPL for DHCOM SoM to permit DFU upload of SPL and subsequent u-boot.itb for recovery or commissioning purposes. The DFU usage procedure is identical to STM32MP1 DHCOR SoM, see commit 3919aa1722a ("ARM: dts: stm32: Add DFU support for DHCOR recovery") , except for switching the SoM into DFU mode. By default, the DHCOM SoM has no dedicated mechanism for setting BOOTn straps into UART/USB mode, therefore to enter DFU mode, the SoC must fail to boot from boot media which can be selected by the BOOTn strap override mechanism first and then fall back to DFU mode. In case of a SoM with pre-populated BOOTn strap override button, power the system off, remove microSD card (if applicable), hold down the BOOTn strap override button located between eMMC and SoM edge connector, power on the SoM. The SoC will fail to boot from SD card and fall back into DFU mode.

The DFU usage procedure is identical to STM32MP1 DHCOR SoM, see commit 3919aa1722a ("ARM: dts: stm32: Add DFU support for DHCOR recovery") , except for switching the SoM into DFU mode. By default, the DHCOM SoM has no dedicated mechanism for setting BOOTn straps into UART/USB mode, therefore to enter DFU mode, the SoC must fail to boot from boot media which can be selected by the BOOTn strap override mechanism first and then fall back to DFU mode. In case of a SoM with pre-populated BOOTn strap override button, power the system off, remove microSD card (if applicable), hold down the BOOTn strap override button located between eMMC and SoM edge connector, power on the SoM. The SoC will fail to boot from SD card and fall back into DFU mode.

ARM: dts: stm32: Add DFU support for DHCOM recovery This patch configures U-Boot SPL for DHCOM SoM to permit DFU upload of SPL and subsequent u-boot.itb for recovery or commissioning purposes.
