This is safe to do, because updating the Linux clock tree to reflect reality will always be glitch-free. Another reason to this patch is that powersave image BT music requires dram to be 400MTS, so clk_set_parent(dram_alt_src, sys1_pll_800m); is required. Without this patch, it will not succeed.

In order to make sure MIPI DSI works well after suspend/resume, the LVDS pixel and phy clocks must be initialized before the MIPI tx_esacpe and rx_escape clocks. LVDS phy, LVDS pixel, tx_escape, and rx_esacpe are all on the same MSLICE. They all share the same clock parent. So, setting the parent source or rate affects all of these clocks. In the LVDS use case the MIPI tx_escape and rx_escape are not saved and restored. So, LVDS works for either clock initialization order. For MIPI case, LVDS must be initialized first.

Using a dedicated symbols namespace make that clear and help clean the global namespace of symbols other modules do no need.
