The Global Clock Controller (GCC) in the MSM8909 SoC provides clocks, resets and power domains for the various hardware blocks in the SoC. Add a DT schema to describe it, similar to other Qualcomm SoCs. Signed-off-by:

Convert the clock driver to specify parent data rather than parent names, to actually bind using 'clock-names' specified in the DTS rather than global clock names. Use parent_hws where possible to refer parent clocks directly, skipping the lookup. Signed-off-by:

Split and extend existing CLK_AIF_OSR_DIV macro to implement mi2s clocks. This simplifies the driver and removes extra code duplication. The clock mi2s_div_clk used .enable_reg/.enable_bit, however these fields are not used with by the clk_regmap_div_ops, thus they are silently dropped. Clock enablement is handled in the mi2s_bit_div_clk clock. Signed-off-by:

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while also removing some GDSCs. Despite these differences, there are many similarities with SDM670. Add data for SDM670 in the driver for SDM845 to reuse the most of the clock data. Advantages and disadvantages of this approach: + maintenance applies to both sdm670 and sdm845 by default + less duplicate code (clocks) means smaller distro/pre-built kernels with all drivers enabled - clocks for both SoC's must be compiled if the user wants clocks for one specific SoC (both or none) - additional testing needed for sdm845 devices Link: https://android.googlesource.com/kernel/msm/+/443bd8d6e2cf54698234c752e6de97b4b8a528bd%5E%21/#F10Signed-off-by:

This driver will support more than one SoC's set of clocks, and set of GDSCs. This behavior would be unclean with hard-coded static variables. Support it by grabbing clocks, GDSCs, and BCRs in the match data. Signed-off-by:

The Snapdragon 670 clocks will be added into the sdm845 gcc driver. Most of the new clocks, GDSCs, and resets already have reserved IDs but there are some resources that don't. Add the new clock from Snapdragon 670 and document the differences between the SoC parent clocks. Signed-off-by:

Change a53-pll driver to use clk_parent_data rather than always looking up the xo clock in the system clock list. Note, this change also switches the a53-pll from the global `xo' clock to the `xo_board', the clock that is specified as the `xo' clock in the DT file. Signed-off-by:

The clock gating control for TX/RX/WSA core bus clocks would be required to be reset(moved from hardware control) from audio core driver. Thus add the support for the reset clocks. Update the lpass_aon_cc_main_rcg_clk_src ops to park the RCG at XO after disable as this clock signal is used by hardware to turn ON memories in LPASS.

When this property is set, the remoteproc is used to boot the LPASS and therefore lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk clocks would be used to bring LPASS out of reset and the rest of the lpass clocks would be controlled directly by the remoteproc. This is a cleanup done to handle overlap of regmap of lpasscc and lpass_aon blocks. Signed-off-by:

Rather than defining (incorrect) global clocks and clock-names lists, define them per platform using conditionals. Also, while we are at it, mark these properties as required for all platforms for which DT files contained clocks/clock-names for the MMCC nodes from the beginning (in addition to existing MSM8998 this adds MSM8994, SDM630 and SDM660).

Use ARRAY_SIZE() instead of manually specifying num_parents. This makes adding/removing entries to/from parent_data easy and errorproof. This conversion fixes an issue present since the first version of this driver. For the gp1_clk_src, gp2_clk_src and gp3_clk_src it was impossible to select sleep_clk as a prent of the clock, since num_parents was limited to 3 rather than 4. Switching to use num_parents automatically makes sleep_clk available for selection.
