Subject: i2c: busses: make K1 driver default for SpacemiT platforms
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=d38e710fba1806974051972d69fbbd6c69b55734;p=thirdparty%2Fkernel%2Flinux.git

i2c: busses: make K1 driver default for SpacemiT platforms

Enable I2C_K1 by default when ARCH_SPACEMIT is configured to ensure SD
card functionality works out-of-the-box.

SpacemiT K1 boards use I2C-controlled PMICs (like the P1 chip) to
provide SD card power supplies. Without the I2C_K1 driver enabled,
regulators cannot be controlled and SD card detection/operation fails.
