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

+static struct clk tpcc_clk = { + .name = "tpcc", + .parent = &pll0_sysclk2, + .lpsc = DA830_LPSC0_TPCC, + .flags = ALWAYS_ENABLED, +}; +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.
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?
