* clk: qcom: Introduce parent_map tablesGeorgi Djakov2015-03-2415-286/+338
| | | | | | | | | | | | | | | | | | | | | 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: fix RCG M/N counter configurationArchit Taneja2015-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | Currently, a RCG's M/N counter (used for fraction division) is set to either 'bypass' (counter disabled) or 'dual edge' (counter enabled) based on whether the corresponding rcg struct has a mnd field specified and a non-zero N. In the case where M and N are the same value, the M/N counter is still enabled by code even though no division takes place. Leaving the RCG in such a state can result in improper behavior. This was observed with the DSI pixel clock RCG when M and N were both set to 1. Add an additional check (M != N) to enable the M/N counter only when it's needed for fraction division.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes we need to program PLLs with a fixed rate configuration during driver probe. Doing this after we register the PLLs with the clock framework causes the common clock framework to assume the rate of the PLLs are 0. This causes all sorts of problems for rate recalculations because the common clock framework caches the rate once at registration time unless a flag is set to always recalculate the rates. Split the qcom_cc_probe() function into two pieces, map and everything else, so that drivers which need to configure some PLL rates or otherwise twiddle bits in the clock controller can do so before registering clocks. This allows us to properly detect the rates of PLLs that are programmed at boot. Fixes: 49fc825f0cc2 "clk: qcom: Consolidate common probe code" Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

Use tagged initializers so we properly assign the m and n values for each frequency. Furthermore, the mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second element to pll2 instead of pll8, causing the clock driver to recalculate the wrong rate for any clocks using this array along with a rate that uses pll2. Plus the .num_parents field is 3 instead of 4 so you can't even switch the parent to pll3. Finally I noticed that the jpegd clock improperly indicates that the pre-divider width is only 2, when it's actually 4 bits wide.

| * clk: qcom: Support bypass RCG configurationStephen Boyd2014-07-163-14/+47
| | | | | | | | | | | | | | | | | | | | | | In the case of HDMI clocks, we want to bypass the RCG's ability to divide the output clock and pass through the parent HDMI PLL rate. Add a simple set of clk_ops to configure the RCG to do this. This removes the need to keep adding more frequency entries to the tv_src clock whenever we want to support a new rate.

| | | | | | | | | | | | | | | | | | | | | | | | Add a driver for the global clock controller found on IPQ8064 based platforms. This should allow most non-multimedia device drivers to probe and control their clocks. This is currently missing clocks for USB HSIC and networking devices.
