[RFC PATCH v2] clk: Remove BYPASS_PLL_CHECK from PLLs
I have looked at problem with Fermi GPUs where changing to higher clock
led to really bad perfomance (with GpuTest 20x worse perfomance) and later also crashes of the nouveau. It seemed
to be affected by Shader Clock in Voltage Entries in the video BIOS. Disabling
BYPASS_PLL_CHECK in CLK0_CTRL seems to completely fix the issue. I have
tried to search this BYPASS_PLL_CHECK in Nvidia traces but seemed it
wasn't used nowhere for CLK settings.
Removing this works fine, but I don't know what it's really for.
Actual bit setting this BYPASS_PLL_CHECK is on 0x10:
