I don't see any reason not to enable this driver in the 32-bit kernels - we like to keep the difference in the defconfig files as small as possible. Could you add those as well? |

I updated the branch with your suggestion and could you please rename this PR to: “configs: enable Si5351 i2c common clock driver” I can’t edit the title since it’s from a fork. Thanks! |

Enable common clock driver for Silicon Labs Si5351a/b/c i2c programmable clock generators.
Si5351 is used in zBitx[1] sBitx[2] radio transceivers running on Raspberry Pi Zero 2 W and 4. These radios are widely used
and have an active community of over 7,000 members[3]. Enabling this driver makes it easier for us to move the Si5351 to kernel i2c, as we are currently using bitbanged i2c in userspace.
