#1167157 — Re: [RFC] drivers/clk/Kconfig: Change COMMON_CLK to tristate

Drop linux-i2c mailing list.

Michael/Paul,

Please review and tell me if this is a bad idea. I am working on a platform
COMMON_CLK is not enabled. The clock I need is on a PCIe card. I don't think
modify platform Kconfig is right. So modifying drivers/clk/Kconfig seems
reasonable to me.
