[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.


Taniya Das (5):
  clk: qcom: clk-alpha-pll: Increase PLL lock detect poll time
  clk: Enable/Disable runtime PM for clk_summary
  clk: qcom: gcc-sc7280: Mark gcc_cfg_noc_lpass_clk always enabled
  dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
  clk: qcom: lpass: Add support for LPASS clock controller for SC7280
