[PATCH 00/10] Update BSH SystemMaster device trees and add SMM-M2B support
From: Haoning Cheng
Date: Wed Nov 04 2026 - 02:38:12 EST
Add basic device tree support for the BSH SMM-M2B SystemMaster,
a hardware variant of the BSH SMM-M2 equipped with an AIC Wi-Fi
and Bluetooth chip.
This series adds the SMM-M2B board compatible to the Freescale
device tree bindings.
Configure the NAND controllers on the BSH SMM-M2 and SMM-S2 to
use the minimum required ECC strength, and enable the RNGB hardware
random number generator on the SMM-M2.
Adjust the Wi-Fi and Bluetooth enable pin settings, configure the
WLAN host wake pin with a pull-down, and remove the unused
cap-sdio-irq property.
Move the hardware definitions shared by the SMM-M2 variants into
a common device tree include file to reduce duplication.
Add the SMM-M2B board device tree and Makefile entry, reusing
the common hardware definitions.
Configure the UART2 pin multiplexing for the shared SMM-M2 hardware.
Enable USB OTG mode on the BSH SMM-M2 and SMM-S2 board variants.
Finally, add a device tree overlay for the SPI display and
touchscreen on the BSH SMM-M2.
