2024-09-27i2c: keba: I2C_KEBA should depend on KEBA_CP500Geert Uytterhoeven1-0/+1
The KEBA I2C controller is only present on KEBA PLC devices. Hence add a dependency on KEBA_CP500, to prevent asking the user about this driver when configuring a kernel without KEBA CP500 system FPGA support.

2024-09-10i2c: keba: Add KEBA I2C controller supportGerhard Engleder1-0/+11
The KEBA I2C controller is found in the system FPGA of KEBA PLC devices. It is used to connect EEPROMs and hardware monitoring chips. The It is a simple I2C controller with a fixed bus speed of 100 kbit/s. The whole message transmission is executed by the driver. The driver triggers all steps over control, status and data register. There are no FIFOs or interrupts. Signed-off-by: Gerhard Engleder <[email protected]> Signed-off-by: Andi Shyti <[email protected]>

2024-07-20i2c: piix4: Register SPDsThomas Weißschuh1-0/+1
The piix4 I2C bus can carry SPDs, register them if present. Only look on bus 0, as this is where the SPDs seem to be located. Only the first 8 slots are supported. If the system has more, then these will not be visible. The AUX bus can not be probed as on some platforms it reports all devices present and all reads return "0". This would allow the ee1004 to be probed incorrectly.

2024-05-06i2c: add zhaoxin i2c controller driverHans Hu1-0/+10
Add Zhaoxin I2C controller driver. It provides the access to the i2c busses, which connects to the touchpad, eeprom, I2S, etc. Zhaoxin I2C controller has two separate busses, so may accommodate up to two I2C adapters. Those adapters are listed in the ACPI namespace with the IIC1D17 HID, and probed by a platform driver. The driver works with IRQ mode, and supports basic I2C features. Flags I2C_AQ_NO_ZERO_LEN and I2C_AQ_COMB_WRITE_THEN_READ are used to limit the unsupported access.

The original change adds usage of i2c_root_adapter(), which is implemented in i2c-mux.c. Therefore we can't use the multiplexing if I2C_I801=y and I2C_MUX=m.
