[PATCH v9 0/2] i2c: ls2x: Add clock- related properties and parsing

Hi all:

This patch set adds clock related properties and parsing in dts and acpi.

======
V9:
Patch (2/2):
- Rewrite the commit description
- Use 64-bit arithmetic to avoid integer overflow during the clock calculation
- Add checks to reject zero clock rates and ensure valid clock inputs
- Modify the comment for clocks and clock-div properties
- Add Tested-by tag from Xi Ruoyao, thanks

V8:
Patch (2/2):
Fix the potential issues from Sashiko AI review:
 - Add error checking for the pointer returned by devm_clk_get_optional_enabled();
 - Add zero-value checking for the match data to provide default div.

V7:
Patch (2/2):
Fix the potential issues from Sashiko AI review:
 - Move the clock property parsing process to probe function to solve the issue
   of calling `devm_clk_get_optional_enabled()` dynamically causes unbounded memory
   leaks and unbalanced clock enable counts.
 - Add non-zero checking to priv->div.

V5:
Patch (1/2):
 - Adjust the position of #include <dt-bindings/clock/loongson,ls2k-clk.h>;
 - Add CC stable; 
 - Fix Signed-off-by.
Patch (2/2):
 - Replace 2K0500/2K1000/2K2000 with LS2K0500/2K1000/2K2000;
 - Replace 7A1000/7A2000 with LS7A1000/7A2000;
 - Replace if (clk && !IS_ERR(clk)) with if(!IS_ERR_OR_NULL(clk));
 - Add document that clocks and clock-div are only ACPI properties in ACPI;
 - Remove unsigned int cast in code (unsigned long)device_get_match_data(dev);
 - Add CC stable; 
 - Fix Signed-off-by.

V4:
- Add Acked-by tag from Conor Dooley, thanks.
Patch (2/2):
 - Adjust the position of #include <linux/clk.h>;
 - Remove struct ls2x_i2c_chip_data and use macro to describe div;
 - Use div instead of factor in ls2x_i2c_adjust_bus_speed;
 - Reverse the "if & else" code logic in ls2x_i2c_adjust_bus_speed;

The PATCH v3 is incomplete, v4 is the replacement of v3, so the previous patch link is v2.

V2:
[PATCH v2] dt-bindings: i2c: ls2x-i2c: Add clocks and clock-frequency properties
- Remove the custom properties clock-input and clock-div, use clock framework;
[PATCH v2] i2c: ls2x: Add clocks property parsing and adjust bus speed
- Use clock framework to obtain the i2c reference clock in dts.
