+Subject: pcie: qcom: Fixed pcie_phy_clk branch issue
+
+Following backtraces are observed in PCIe deinit operation.
+
+ Hardware name: Qualcomm (Flattened Device Tree)
+ (unwind_backtrace) from [] (show_stack+0x10/0x14)
+ (show_stack) from [] (dump_stack+0x84/0x98)
+ (dump_stack) from [] (warn_slowpath_common+0x9c/0xb8)

+ (warn_slowpath_fmt) from [] (clk_branch_wait+0x114/0x120)
+ (clk_branch_wait) from [] (clk_core_disable+0xd0/0x1f4)
+ (clk_core_disable) from [] (clk_disable+0x24/0x30)
+ (clk_disable) from [] (qcom_pcie_deinit_v0+0x6c/0xb8)
+ (qcom_pcie_deinit_v0) from [] (qcom_pcie_host_init+0xe0/0xe8)
+ (qcom_pcie_host_init) from [] (dw_pcie_host_init+0x3b0/0x538)
+ (dw_pcie_host_init) from [] (qcom_pcie_probe+0x20c/0x2e4)
+
+pcie_phy_clk is generated for PCIe controller itself and the
+GCC controls its branch operation. This error is coming since
+the assert operations turn off the parent clock before branch
+clock. Now this patch moves clk_disable_unprepare before assert
+operations.
+
+Similarly, during probe function, the clock branch operation
+should be done after dessert operation. Currently, it does not
+generate any error since bootloader enables the pcie_phy_clk
+but the same error is coming during probe, if bootloader
+disables pcie_phy_clk.
