Hi,
If required, it's more appropriate that the dev-i2cX.c is in the
plat-samsung
like other dev-i2c[0-2].c even though I2C3~I2C7 are not used on S3C SoCs.
Because they which are separated in two places can cause confusion and the
same reason, it is better to keep the s3c_i2cX_cfg_gpio than s5p_i2cX...
Thanks.
Best regards,
Kgene.
