c366be72 - i2c: Add driver for the RTL9300 I2C controller

Wed, 06 Nov 2024 00:18:35 +0000

i2c: Add driver for the RTL9300 I2C controllerAdd support for the I2C controller on the RTL9300 SoC. There are two I2Ccontrollers in the RTL9300 that are part of the Ethernet switch registerblock. Each of these controllers owns a SCL pin (GPIO8 for the fiorstI2C controller, GPIO17 for the second). There are 8 possible SDA pins(GPIO9-16) that can be assigned to either I2C controller. Thisrelationship is represented in the device tree with a child node foreach SDA line in use.This is based on the openwrt implementation[1] but has beensignificantly modified[1] - https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/realtek/files-5.15/drivers/i2c/busses/i2c-rtl9300.cSigned-off-by: Chris Packham Reviewed-by: Andi Shyti Signed-off-by: Andi Shyti List of files: /linux-6.15/drivers/i2c/busses/Kconfig

b7ef4e0b - i2c: Drop legacy muxing pseudo-drivers

Tue, 22 Oct 2024 10:00:27 +0000

i2c: Drop legacy muxing pseudo-driversThe i2c-amd756-s4882 and i2c-nforce2-s4985 muxing pseudo-drivers werewritten at a time when the i2c core did not support muxing. They areessentially board-specific hacks. If we had to add support for theseboards today, we would implement it in a completely different way.These Tyan server boards are 19 years old by now, so I very much doubtany of these is still running today. So let's just drop this clumsycode. If anyone really still needs this support and complains, I'llrewrite it in a proper way on top of i2c-mux.This also fixes the following warnings:drivers/i2c/busses/i2c-amd756.c:286:20: warning: symbol 'amd756_smbus' was not declared.

This enhancement includes:- Adding functionality to identify and select the supported ASF functions.- Implementing mechanisms for registering and deregistering I2C slave devices.- Providing support for data transfer operations over ASF.Additionally, include a 'select' Kconfig entry as the current patchutilizes .reg_slave() and .unreg_slave() callbacks, which are controlledby CONFIG_I2C_SLAVE.Reviewed-by: Andy Shevchenko Co-developed-by: Sanket Goswami Signed-off-by: Sanket Goswami Signed-off-by: Shyam Sundar S K Signed-off-by: Andi Shyti List of files: /linux-6.15/drivers/i2c/busses/Kconfig

c509ebdb - i2c: amd-asf: Add ACPI support for AMD ASF Controller

Mon, 23 Sep 2024 08:03:57 +0000

i2c: amd-asf: Add ACPI support for AMD ASF ControllerThe AMD ASF controller is presented to the operating system as an ACPIdevice. The AMD ASF driver can use ACPI to obtain information about theASF controller's attributes, such as the ASF address space and interruptnumber, and to handle ASF interrupts.Currently, the piix4 driver assumes that a specific port address isdesignated for AUX operations. However, with the introduction of ASF, thesame port address may also be used by the ASF controller. Therefore, acheck needs to be added to ensure that if ASF is advertised and enabled inACPI, the AUX port should not be configured.Reviewed-by: Andy Shevchenko Co-developed-by: Sanket Goswami Signed-off-by: Sanket Goswami Signed-off-by: Shyam Sundar S K Signed-off-by: Andi Shyti List of files: /linux-6.15/drivers/i2c/busses/Kconfig
