* clk: qcom: Fix ipq806x LCC frequency tablesStephen Boyd2015-03-27
| | | | | | | | | | These frequency tables list the wrong rates. Either they don't have the correct frequency at all, or they're specified in kHz instead of Hz. Fix it.

* clk: qcom: Introduce parent_map tablesGeorgi Djakov2015-03-23
| | | | | | | | | | | | | | | | | | | | | In the current parent mapping code, we can get duplicate or inconsistent indexes, which leads to discrepancy between the number of elements in the array and the number of parents. Until now, this was solved with some reordering but this is not always possible. This patch introduces index tables that are used to define the relations between the PLL source and the hardware mux configuration value. To accomplish this, here we do the following: - Define a parent_map struct to map the relations between PLL source index and register configuration value. - Add a qcom_find_src_index() function for finding the index of a clock matching the specific PLL configuration. - Update the {set,get}_parent RCG functions use the newly introduced parent_map struct. - Convert all existing drivers to the new parent_map tables.

* | clk: qcom: Properly change rates for ahbix clockStephen Boyd2015-03-12
|/ | | | | | | | | | | | The ahbix clock can never be turned off in practice. To change the rates we need to switch the mux off the M/N counter to an always on source (XO), reprogram the M/N counter to get the rate we want and finally switch back to the M/N counter. Add a new ops structure for this type of clock so that we can set the rate properly.
