LPSC names for SCRx_SS are same here.
Yeah, I've noticed that cut-and-paste mistake too. :-)

LPSC for tpcc (LPSC number ZERO) will not get enabled because of the
(clk->lpsc) check in davinci_clk_init function in
arch/arm/mach-davinci/clock.c file. You can add the CLK_PSC flag
above along with ALWAYS_ENABLED.
Yes, this is a bit of a hack to handle PSC = 0.
It's not PSC = 0, it's module 0 within PSC.
Which is the same as LPSC as the documentation tells me now, so 'lpsc'
name was correct. But it's *not* the same thing as PSC. What a naming mess... :-/
I had to do the same for VPSSMSTR on dm644x.
Now tell me what that check is for, if one has to hack around it?
