Milk-V Mars CM and Mars CM Lite System-on-Module both are based on the
StarFive JH7110 SoC and compatible with the Raspberry Pi CM4IO Classic IO
Board carrier. Mars CM Lite is Mars CM without the eMMC storage component
on mmc0 and the mmc0 interface configured instead for SD Card use. The
optional WiFi+BT chipset is connected via SDIO on the mmc1 interface that
would otherwise be connected to an SD Card slot on the StarFive
VisionFive2 reference design.
Add the related devicetree files for both Milk-V Mars CM and Milk-V Mars
CM Lite describing the currently supported features, namely PMIC, UART,
I2C, GPIO, eMMC or SD Card, WiFi+BT, QSPI Flash, and Ethernet.
Caveat with vendor AP6256 firmware files present the firmware loading is
successful but subsequently fails IRQ wake initialization. Common GPIO
conflicts for "WiFi" optioned boards having this module:
pwmdac_pins:
- AP6256: WL_REG_ON>>WIFI_REG_ON_H_GPIO33
- AP6256: WL_HOST_WAKE>>WIFI_WAKE_HOST_H_GPIO34
i2c2_pins:
- AP6256: UART_CTS_N<<UART1_RTSn_GPIO2
- AP6256: UART_RTS_N>>UART1_CTSn_GPIO3
i2c6_pins:
- AP6256: UART_RXD<<UART_TX_GPIO16
- AP6256: UART_TXD>>UART_RX_GPIO17
Tested successfully for basic mmc0 storage, USB, and network functionality on:
- Milk-V Mars CM 8GB
- Milk-V Mars CM Lite 4GB
- Milk-V Mars CM Lite WiFi 8GB
Changes since v2:
- PATCH 3/5 delete newline at end of file
- PATCH 5/5 delete newline at end of file

Milk-V Mars CM Lite is a System-on-Module based on the Milk-V Mars CM
without the onboard eMMC storage component populated and configured
instead for SD3.0 Card Slot on that interface via 100-pin connector.

Link to StarFive JH7110 Technical Reference Manual: https://doc-en.rvspace.org/JH7110/TRM/index.html
Link to Raspberry Pi CM4IO datasheet: https://datasheets.raspberrypi.com/cm4io/cm4io-datasheet.pdf
Add the devicetree file to make use of StarFive JH7110 common supported
features PMIC, EEPROM, UART, I2C, GPIO, PCIe, QSPI Flash, PWM, and
Ethernet. Also configure the eMMC interface mmc0 for SD Card use and
configure the common SD Card interface mmc1 for onboard SDIO BT+WiFi.
