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

 



Update the GDSC default values of GDSC transition delay to avoid the
issues in the GDSC FSM state.

Fixes: fae7617bb142 ("clk: qcom: Add video clock controller driver for SC7280")
Fixes: 1daec8cfebc2 ("clk: qcom: camcc: Add camera clock controller driver for SC7280")
Fixes: a3cc092196ef ("clk: qcom: Add Global Clock controller (GCC) driver for SC7280")
Fixes: 3e0f01d6c7e7 ("clk: qcom: Add graphics clock controller driver for SC7280")
