The change to enable OMAP5 support on this platform was a little too
eager in adding a 'select' for a particular clock driver that might
not be enabled in all configurations, which in turn leads to a build
error:

warning: (SND_OMAP_SOC_OMAP_ABE_TWL6040) selects COMMON_CLK_PALMAS which has unmet direct dependencies (COMMON_CLK && MFD_PALMAS)
drivers/built-in.o: In function `palmas_clks_probe':
drivers/clk/clk-palmas.c:228: undefined reference to `palmas_ext_control_req_config'

I do not see a strong dependency here, so it's probably better to
drop this select and to avoid adding more complexity here.

Would it be better to have this changed to:
	select COMMON_CLK_PALMAS if MFD_PALMAS
instead of removing.

All OMAP5 boards uses Palmas as PMIC and the boards where twl6040 audio is in
use the 32K clock for the codec is coming from Palmas.
Without this clock the twl6040 will not boot up causing errors during probe time.

It's possible to build a kernel with omap5 support and this driver but
no palmas support, which makes the dependency it a bit strange, but I'll
let Mark decide.

Unfortunately, I've sent the changed v2 patch without fixing up the commit
message. Instead of sending another v3 right away, I'll wait for Mark
to comment.

Well, I wasn't going to look until Peter reviewed it...

Please don't send new patches in reply to existing threads, it makes it
easy for those new patches to get dropped and it can get very hard to
follow what's the current version.
