This patch set implements the System manager bus (SMBus) module in NPCM7XX SoC. Basically, it emulates the data transactions of the module, not the SDA/SCL levels. We have also added a QTest which contains read and write operations for both single-byte and FIFO mode, and added basic I2C devices for npcm750-evb and quanta-gsj boards.
We also cleaned up the unimplemented GPIO devices in npcm7xx.c since they are already implemented. Changes since v1: - Fix errors for i2c device addresses for temperature sensors in GSJ machine - Use at24c device to emulate GSJ EEPROM. It supports more than 256 bytes. - Fill in VMState in npcm7xx_smbus.c - Change commit message in patch 3 and 4 - Fix order in npcm7xx.c IRQ list - Add a few extra comments to make things clearer Hao Wu (6): hw/arm: Remove GPIO from unimplemented NPCM7XX hw/i2c: Implement NPCM7XX SMBus Module Single Mode hw/arm: Add I2C sensors for NPCM750 eval board hw/arm: Add I2C sensors and EEPROM for GSJ machine hw/i2c: Add a QTest for NPCM7XX SMBus Device hw/i2c: Implement NPCM7XX SMBus Module FIFO Mode default-configs/devices/arm-softmmu.mak | 1 + docs/system/arm/nuvoton.rst | 2 +- hw/arm/npcm7xx.c | 76 +- hw/arm/npcm7xx_boards.c | 46 + hw/i2c/meson.build | 1 + hw/i2c/npcm7xx_smbus.c | 1097 +++++++++++++++++++++++ hw/i2c/trace-events | 12 + include/hw/arm/npcm7xx.h | 2 + include/hw/i2c/npcm7xx_smbus.h | 113 +++ tests/qtest/meson.build | 1 + tests/qtest/npcm7xx_smbus-test.c | 495 ++++++++++ 11 files changed, 1821 insertions(+), 25 deletions(-) create mode 100644 hw/i2c/npcm7xx_smbus.c create mode 100644 include/hw/i2c/npcm7xx_smbus.h create mode 100644 tests/qtest/npcm7xx_smbus-test.c -- 2.30.0.365.g02bc693789-goog
