This small series fix a current problem with ipq8074 where the 2 uniphy port doesn't work in some corner case with some clk configuration. The port to correctly work require a specific frequency, using the wrong one results in the port not transmitting data. With the current code with a requested freq of 125MHz, the frequency is set to 105MHz. This is caused by the fact that there are 2 different configuration to set 125MHz and it's always selected the first one that results in 105MHz. In the original QSDK code, the frequency configuration selection is different and the CEIL FLOOR logic is not present. Instead it's used a BEST approach where the frequency table is checked and then it's checked if there are duplicate entry. This proposed implementation is more specific and keep the CEIL FLOOR logic while maitaining the possibility to provide multiple configuration. The first 2 patch drop redundant F entry redefinition. The 3rd one implement the change with also some macro description on how this new implementation works The 4th one migrate the gcc-ipq8074 driver to this new implementation.
