Merge tag 'qcom-clk-for-6.11-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom

Pull more qcom clk driver updates from Bjorn Andersson:

 - Introduces helper logic to expose clock controllers as simple
   interconnect providers
 - Use the interconnect helper above on Qualcomm ipq9574
 - Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on Qualcomm
   X1Elite.
 - Improve error handling in Qualcomm kpss-xcc driver
 - Mark Qualcomm SC8280XP LPASS clock controller regmap_config const
