Eduard Iten 8051f18b9b Fix USB configuration for Zephyr 4.2.0 
- Use CONFIG_USB_DEVICE_STACK_NEXT (new USB stack)
- Replace CONFIG_USB_CDC_ACM with CONFIG_USBD_CDC_ACM_CLASS
- Remove deprecated CONFIG_USB_DEVICE_COMPOSITE
- Add CONFIG_HAS_STM32CUBE=y to defconfig (required for USB)
- Remove networking configs (not needed for basic USB CDC)
- Based on actual Zephyr 4.2.0 samples

Eduard Iten 05a25c3900 Simplify board configuration following candlelight example 
- Minimal defconfig like candlelight (only GPIO and CAN)
- Remove SOC and clock configs that are auto-detected
- Change vendor from 'ews' to 'others' like candlelight
- Let Zephyr auto-configure SOC and clock settings

Eduard Iten 0d26789e6a Simplify FDCAN configuration following candlelight example 
- Remove bit-rate properties that are not declared in binding
- Use minimal FDCAN configuration like candlelight board
- Keep only pinctrl and status properties

Eduard Iten 1511b91050 Fix Zephyr 4.2.0 configuration issues 
- Remove CONFIG_BOARD_EWS from defconfig (auto-generated in new Zephyr)
- Replace deprecated 'bus-speed' with 'bit-rate' properties for FDCAN
- Replace deprecated 'bus-speed-data' with 'bit-rate-data' properties

Eduard Iten ece99aa5b8 Fix CAN configuration: use FDCAN2 instead of FDCAN1 
- Change from fdcan1 to fdcan2 for PB0/PB1 pins on STM32G0B1
- Update pinctrl references to fdcan2_rx_pb0 and fdcan2_tx_pb1
- Update zephyr,canbus reference to fdcan2

Eduard Iten d58a18bd4b Remove west workspace configuration files 
- Remove west.yml and .west/config that interfered with existing workspace
- Project should work in existing Zephyr workspace without these files

Eduard Iten 32e92e732d Fix board.yml format for Zephyr 4.2.0 
- Update board.yml to new Zephyr 4.2 format with 'board:' root key
- Add CONFIG_BOARD_EWS=y to defconfig
- Remove west workspace files (not needed in git)

Eduard Iten 9fd882889f Rename board from ews_board to ews and fix board discovery 
- Rename board directory: ews_board -> ews
- Rename board files: ews_board.dts -> ews.dts, ews_board_defconfig -> ews_defconfig
- Update board identifier and compatible strings
- Add board.cmake for runner configuration
- Set BOARD_ROOT in CMakeLists.txt to enable custom board discovery
- Update all documentation with new board name: west build -b ews

Eduard Iten 3d328fb7a2 Add initial CAN FD CDC composite firmware 
- Custom board definition for STM32G0B1KBU6 (ews_board)
- Zephyr-based firmware with modular architecture
- USB composite device: gs_usb CAN FD + CDC ACM interfaces
- PFET control via CDC text commands (PA8, PB2)
- Status LED on PB4, CAN FD on PB0/PB1
- No external crystal - uses HSI with USB clock recovery
- Ready for build testing with: west build -b ews_board
