Add divider table to optfclk_pciephy_div clock. The Documentation
for divider clock can be found at ../clock/ti/divider.txt
This patch requires a better changelog. Why is the change done, any TRM refs etc.?
The 8th bit of CM_CLKMODE_APLL_PCIE can be programmed to either 0x0 or 0x1
based on if the divider value is 0x2 or 0x1.
Figure 26-21. PCIe PHY Clock Generator Overview in vE of DRA7xx ES1.0 shows the
block diagram of Clock Generator Subsystem of PCIe PHY module. We have to do a
bypass (divided by 1) in order to get the correct PCIE_PHY_DIV_GCLK
Yes, something like this on the changelog would be good.

frequency.
