Use select_i2c_ch_pca9547() only when CONFIG_FSL_USE_PCA9547_MUX is set, but several call in board/nxp/lx2160a/lx2160a.c invoke it unconditionally, or using unrelated Kconfigs (CONFIG_EMC2305, CONFIG_VID). Compilation with LX2160A target that omits the mux therefore fails with error: implicit declaration of function 'select_i2c_ch_pca9547' Add a static inline stub with -EOPNOTSUPP for the !CONFIG_FSL_USE_PCA9547_MUX case so all cases compile cleanly. Adapted from the convention used by include/scmi_nxp_protocols.h for SCMI subprotocol stubs. There is no functional change for NXP boards: all eight upstream LX2160A defconfigs (lx2160ardb / lx2160aqds / lx2162aqds and their secure / stmm / verified_boot variants) already set CONFIG_FSL_USE_PCA9547_MUX=y, so the real declaration wins. The purpose is to support new boards that do not use the PCA9547. Signed-off-by: Vincent Jardin <vjardin@free.fr> Reviewed-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
