[alsa-devel] [PATCH] powerpc: select PPC_CLOCK unconditionally for FSL_SOC
Freescale PowerPC SoCs share a number of IP blocks with Freescale ARM/IMX SoCs, FlexCAN, SSI, FEC, eSDHC, USB, etc. There are some effort consolidating those drivers to make them work for both architectures.
One outstanding difference between two architectures is ARM/IMX will turn off module clocks during platform initialization for power saving and expects drivers manage clocks using clk API, while PowerPC mostly does not do that, and thus does not always build in clk API.
Listing all those driver Kconfig options in "select PPC_CLOCK if" seems not scalable for long term maintenance, and could easily introduce Kconfig recursive dependency. This patch chooses to select PPC_CLOCK unconditionally for FSL_SOC to always build clk API for PowerPC in.

Kumar,
Gentle ping ...

Was on a bit of travel to nowhere, but that's a different story.
What timeframe are you looking for this to go in? 3.4 or 3.5?

Thanks, Shawn
