Subject: [PATCH v3 0/2] Add support for LPASS Core and Audio Clock for SC7280

[v3]
 * Fix 'pm_clk_suspend' expansion warning in lpass_audio_cc_sc7280_probe
   and lpass_aon_cc_sc7280_probe.
 * Update the vco table frequencies.
 * Update 'regmap_config' name for all clock controllers.
 * Fix the missing 'const' for clk_init_data.
 * Update the binding for 'lpass_aon' CC.

[v2]
 * Drop code for "Add support for clock voting from GDSC" from
   drivers/clk/qcom/gdsc.c
 * Add support for runtime PM get/put from clk_summary.
 * Update commit message for PLL detect lock timeout increase.
 * Fix documentation bindings errors reported by DT_CHECKER_FLAGS.
 * Update the driver code to take care of the following
    - KCONFIG to add "select QCOM_GDSC"
    - Use of "const" for pll_vco and clk_init_data
    - Use of index instead of fw_name.
    - Fix extra space, remove 'lpass_create_pm_clks' and corresponding code.
    - cleanup 'lpass_hm_core_probe' and 'lpass_hm_sc7280_match_table'.

[v1]
This patchset supports the following.
- Few PLLs might require to a higher time to detect lock, thus increase the
  polling time.
- GDSC which require clocks to be explicitly enabled before access.
- LPASS core and audio clock driver support for SC7280.
