[PATCH 6.4 440/737] clk: qcom: gcc-qdu1000: Fix gcc_pcie_0_pipe_clk_src clock handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Imran Shaik <quic_imrashai@xxxxxxxxxxx>

[ Upstream commit b311f5d3c4749259043a9a458a8db07915210142 ]

Fix the gcc pcie pipe clock handling as per the clk_regmap_phy_mux_ops
implementation to let the clock framework automatically park the clock
at XO when the clock is switched off and restore the parent when the
clock is switched on.

Fixes: 1c9efb0bc040 ("clk: qcom: Add QDU1000 and QRU1000 GCC support")
