[PATCH 0/2] spi: spi-cadence: Add Slave mode support

WebApr 5, 2024 · 5. "CLK" stands for "CLocK". "S" stands for "Serial". So "SCLK" is "Serial CLocK". You also get "SCL" (often used for I2C) and "SCK" meaning the same thing. An SD card has multiple modes of communication: serial, or 4-bit parallel (called SDIO). A clock is a clock whether it is used for serial or parallel communication. WebThe Serial Peripheral Interface (SPI) is a communication protocol used to transfer data between micro-computers like the Raspberry Pi and peripheral devices.
