2024-11-24dt-bindings: i2c: snps,designware-i2c: declare bus capacitance and clk freq ↵Michael Wu
optimized Since there are no registers controlling the hardware parameters IC_CAP_LOADING and IC_CLK_FREQ_OPTIMIZATION, their values can only be declared in the device tree. snps,bus-capacitance-pf indicates the bus capacitance in picofarads (pF). It affects the high and low pulse width of SCL line in high speed mode. The legal values for this property are 100 and 400 only, and default value is 100. This property corresponds to IC_CAP_LOADING. snps,clk-freq-optimized indicates whether the hardware reduce its internal clock frequency by reducing the internal latency required to generate the high period and low period of SCL line. This property corresponds to IC_CLK_FREQ_OPTIMIZATION. The driver can calculate the high period count and low period count of SCL line for high speed mode based on these two properties.

For the host drivers, this release includes significant updates, with the primary change being the renaming from "master/slave" to "controller/target" to adhere to I2C v7 and SMBus 3.2 standards.

General improvements: - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with RUNTIME_PM_OPS to enable waking up the controller during suspend() before suspend_noirq() kicks in. - Improved logging in the Xilinx driver. - Added a warning (WARN()) in the Renesas R-Car driver for spurious interrupts. DTS Changes: - Removed address-cell and size-cell from the Atmel at91sam, nVidia Tegra 20, and Samsung S3c2410 devices. - Fixed Texas Instruments OMAP4 I2C controller to comply with the i2c-controller.yaml schema. - Improved indentation in DTS examples for several I2C devices. - Converted the NXP LPC1788 binding to the dt-schema. - Added documentation for the compatible string thead,th1520-i2c. - Added the "power-domains" property for the Meson I2C driver.

2024-07-09dt-bindings: i2c: nxp,lpc1788-i2c: convert to dt schemaKanak Shilledar
Convert the NXP I2C controller for LPC2xxx/178x/18xx/43xx to newer DT schema. Created DT schema based on the .txt file which had `compatible`, `reg`, `interrupts`, `clocks`, `#address-cells` and `#size-cells` as required properties. Additional changes to the original .txt binding - added maintainer from the MAINTAINERS file. - added resets property required by the corresponding DTS files.

2024-07-09dt-bindings: i2c: adjust indentation in DTS example to coding styleKrzysztof Kozlowski
Bindings coding style expects 2- or 4-space indentation in the DTS example. Correct files having something odd (6- or 8-space) to 4-space while re-ordering few properties according to DTS coding style (the first property should be compatible, then reg/ranges).

Drop them as well from required properties, even though i2c-controller.yaml does not require them, because I2C controller could be enabled without any children in DTS for user-space usage.

2024-05-06dt-bindings: i2c: renesas,riic: Document R9A09G057 supportLad Prabhakar
Document support for the I2C Bus Interface (RIIC) available in the Renesas RZ/V2H(P) (R9A09G057) SoC. The RIIC interface in the Renesas RZ/V2H(P) differs from RZ/A in a couple of ways: - Register offsets for the RZ/V2H(P) SoC differ from those of the RZ/A SoC. - RZ/V2H register access is limited to 8-bit, whereas RZ/A supports 8/16/32-bit. - RZ/V2H has bit differences in the slave address register. To accommodate these differences, a new compatible string "renesas,riic-r9a09g057" is added.
