i2c: k1: enable both functional and bus clocks

2026-08-25T06:22:24Z

The K1 I2C controller requires both its functional clock and APB bus clock to operate. The device tree provides them as "func" and "bus", but the driver currently acquires and enables only the first clock. Acquire both clocks by name and enable them during probe. Use explicit named lookups instead of the bulk clock API to align with the K1 Linux driver and keep the roles of the two clocks clear if functional clock rate configuration is needed later.

i2c: k1: fix wrong bus speed setting

2026-08-25T06:22:24Z

The controller bus mode should be selected according to the requested I2C bus speed. However, the driver currently passes the functional clock rate to k1_i2c_set_bus_speed(), so the selected mode does not reflect the requested bus speed. Fix this by reading the clock-frequency property from the Device Tree, defaulting to standard speed, and drop the unused clk_rate field.
