* dt-bindings: i2c: snps,designware-i2c: declare bus capacitance and clk freq ↵Michael Wu2024-11-241-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. New Support: - Added support for Intel Arrow Lake-H - Added I2C support in the Arioha SoC by linking the Mediatek I2C controller Cleanups: - Added the MODULE_DESCRIPTION() macro, resolving a modpost warning in the ALi 1563 Southbridge driver. - Constified the regmap_config declaration in the i2c-designware driver. - Improved the coding style in the Renesas R-Car driver by removing unnecessary semicolons after brackets. 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.

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.

Description of this property is added to all peripheral binding files of the peripheral under the STM32 firewall controller. It allows an accurate representation of the hardware, where various peripherals are connected to a firewall bus. The firewall can then check the peripheral accesses before allowing its device to probe.
