Subject: [PATCH v2 0/2] Add Amlogic A311D2 and Khadas Vim4 Board Support
Date: Tue, 20 Jun 2023 14:48:55 +0100 [thread overview]
Message-ID: <20230620134857.238941-1-tanure@linux.com> (raw)
The Khadas VIM4 uses the Amlogic A311D2 SoC, based on the Amlogic
Meson T7 family. This chip is not the same as A311D used in Vim3
board.
Work based on Khadas 5.4 branch:
https://github.com/khadas/linux/tree/khadas-vims-5.4.y
The current status is Vim4 board booting to emergency shell via uart.
Board Features:
- 8GB LPDDR4X 2016MHz
- 32GB eMMC 5.1 storage
- 32MB SPI flash
- 10/100/1000 Base-T Ethernet
- AP6275S Wireless (802.11 a/b/g/n/ac/ax, BT5.1)
- HDMI 2.1 video
- HDMI Input
- 1x USB 2.0 + 1x USB 3.0 ports
- 1x USB-C (power) with USB 2.0 OTG
- 3x LED's (1x red, 1x blue, 1x white)
- 3x buttons (power, function, reset)
- M2 socket with PCIe, USB, ADC & I2C
- 40pin GPIO Header
- 1x micro SD card slot
Changes Since v1:
- Drop the T7 clock driver as it is not needed for serial boot. It will
later use the S4 clock
driver as S4 and T7 seems to be similar chips.
- Use "arm,gic-400" for interrupt controller to fix dtb_check
- Remove CPU node properties not needed for serial boot
- Move UART node to apb4 node
- Drop T7 UART compatible line and use S4 uart
- Use psci V1 instead of 0.2, it works, but I can't verify is correct
as the datasheet I have
doesn't contain that information.
- Remove compatible from meson-t7.dtsi, move it to vim4 board dts
- Add memory node with 8GB. Not sure about this one, works without,
but doesn't detect 8GB
- Use defines for GIC_CPU_MASK_SIMPLE, IRQ_TYPE_LEVEL_LOW,
IRQ_TYPE_LEVEL_HIGH instead of hardcoded values
