This patch series add the clock controller of qca8363/qca8084, and add the clock ops clk_branch2_prepare_ops to avoid spin lock used during the clock operation of qca8k clock controller where the sleep happens when accessing clock control register by MDIO bus. Changes in v2: * remove clock flag CLK_ENABLE_MUTEX_LOCK. * add clock ops clk_branch2_qca8k_ops. * improve yaml file for fixing dtschema warnings. * enable clock controller driver in defconfig. Changes in v3: * rename clk_branch2_qca8k_ops to clk_branch2_mdio_ops. * fix review comments on yaml file. * use dev_err_probe on driver probe error. * only use the compatible "qcom,qca8084-nsscc". * remove enable clock controller driver patch. Changes in v4: * add _qcom_cc_really_probe function. * commonizing the probe function. * remove flag CLK_IS_CRITICAL from clocks only needed to be enabled in switch device. * update device tree property reg to 0x10. Changes in v5: * commonize qcom_cc_really_probe. * add halt_check for the branch clocks. * fix the review comments on nsscc-qca8k.c. Changes in v6: * rename clk_branch2_mdio_ops to clk_branch2_prepare_ops. Changes in v7: * remove the clock flag CLK_IS_CRITICAL. * optimize the file nsscc-qca8k.c. * identify & fix the comments from Stephen. Changes in v8: * add dependency on ARM in Kconfig. Changes in v9: * take the clk_ops clk_rcg2_mux_closest_ops to remove the redundant freq_tbls. Changes in v10: * fix the patch CHECK and improve the comments. Changes in v11: * update the clock names to reflect hardware connecton.
