But this clk need enable,so make it as critical. The ddrphy/ddrupctl clks no driver to handle them, Chip design requirements for these clock to always on, The pmu_hclk_otg0 is Chip design defect, must be always on, Signed-off-by: Elaine Zhang Signed-off-by: Heiko Stuebner --- diff --git a/drivers/clk/rockchip/clk-rk3368.c b/drivers/clk/rockchip/clk-rk3368.c index 024762d3214d..fc56565379dd 100644 --- a/drivers/clk/rockchip/clk-rk3368.c +++ b/drivers/clk/rockchip/clk-rk3368.c @@ -638,7 +638,7 @@ static struct rockchip_clk_branch rk3368_clk_branches[] __initdata = { GATE(SCLK_MAC_TX, "sclk_mac_tx", "mac_clk", 0, RK3368_CLKGATE_CON(7), 5, GFLAGS), - GATE(0, "jtag", "ext_jtag", 0, + GATE(0, "jtag", "ext_jtag", CLK_IGNORE_UNUSED, RK3368_CLKGATE_CON(7), 0, GFLAGS), COMPOSITE_NODIV(0, "hsic_usbphy_480m", mux_hsic_usbphy480m_p, 0, @@ -861,6 +861,9 @@ static const char *const rk3368_critical_clocks[] __initconst = { "pclk_pd_alive", "pclk_peri", "hclk_peri", + "pclk_ddrphy", + "pclk_ddrupctl", + "pmu_hclk_otg0", }; static void __init rk3368_clk_init(struct device_node *np)
