Tue, 26 May 2026 16:36:57 +0200

i2c: busses: make K1 driver default for SpacemiT platformsEnable I2C_K1 by default when ARCH_SPACEMIT is configured to ensure SDcard functionality works out-of-the-box.SpacemiT K1 boards use I2C-controlled PMICs (like the P1 chip) toprovide SD card power supplies. Without the I2C_K1 driver enabled,regulators cannot be controlled and SD card detection/operation fails.Suggested-by: Margherita Milani Suggested-by: Yixun Lan Signed-off-by: Iker Pedrosa Reviewed-by: Yixun Lan Signed-off-by: Andi Shyti Link: https://lore.kernel.org/r/20260526-orangepi-sd-card-i2c-v1-1-b92268bfd467@gmail.com List of files: /linux/drivers/i2c/busses/Kconfig
