Subject: [PATCH v4 0/2] Add Meta (Facebook) SanMiguel BMC (AST2620)
Date: Mon, 23 Mar 2026 20:41:04 +0800 [thread overview]
Message-ID: <20260323-sanmiguel_init_dts-v4-0-caaa48a7f7be@gmail.com> (raw)
Add Linux device tree entries for Meta (Facebook) SanMiguel specific
devices connected to the AST2620 BMC SoC.

Changes in v4:
- Include openbmc-flash-layout-128-alt.dtsi in flash1.
- Rearrange the DTS nodes and properties alphabetically.
- Disable the internal pull-down resistors for below GPIO pins
- GPIOM4, GPIOM5, GPIOV4, GPIOV7
- Adjust GPIO liname
- Move `PCB_TEMP_ALERT-I` (GPIOV5 --> GPIOV4)
- Add `HSC4_S5_OR_S0_N-O` (pdb_ioexp_20, p12)
- Link to v3: https://lore.kernel.org/r/20260311-sanmiguel_init_dts-v3-0-2b4d1ab7a8a1@gmail.com
Changes in v3:
- Update the model name to "Facebook SanMiguel BMC".
- Remove CP2112 and downstream IOEXP nodes as the upstream driver
is not yet available.
- Remove the following EEPROM nodes until the bus numbers and
addresses are confirmed:
- 3-0051: HMC FRU EEPROM
- 3-0052: HPM0 FRU EEPROM
- 3-0053: HPM1 FRU EEPROM
- Change the compatible property of the following EEPROM nodes
from 24c02 to 24c128:
- 5-0050: SMM FRU EEPROM
- 9-0050: PDB FRU EEPROM
- 13-0055: SMM EXT FRU EEPROM
- Fix the smm_temp node address typo (0x4e -> 0x48).
- Remove nodes that no longer exist in the latest board design:
- 19-006f: RTC (nct3018y)
- 9-0075: IO expander (pca9555)
- Update linenames to match the reference design:
- B0_M0_AIC_USB_EN-O -> B0_M0_CPU_L0_RST_IND_L-O
- B0_M0_BRD_ID_2-I -> B0_M0_BMC_TO_GPU_MCU_I2C_EN-O
- B1_M0_AIC_USB_EN-O -> B1_M0_CPU_L0_RST_IND_L-O
- B1_M0_BRD_ID_2-I -> B1_M0_BMC_TO_GPU_MCU_I2C_EN-O
- IOX_GPIO_P16_TP -> USB2_BMC_HUB2_RST_L-O
- I2C_PDB_ALERT_L-I -> X86_TPM_RST_SEL_L-O
- Remove unexpected or unsupported properties from SSIF and IOEXP
nodes.
- Change all status values from "ok" to "okay" for consistency.
- Link to v2: https://lore.kernel.org/r/20260203-sanmiguel_init_dts-v2-0-6a5682c32b38@gmail.com
Changes in v2:
- change mac0 phy-mode to rgmii-id
- remove max-speed attribute from mac0
- Link to v1: https://lore.kernel.org/r/20260202-sanmiguel_init_dts-v1-0-c0023ae41899@gmail.com
