clk: imx: imx8mp: add shared clk gate for usb suspend clk 32K usb suspend clock gate is shared with usb_root_clk, this shared clock gate was initially defined only for usb suspend clock, usb suspend clk is kept on while system is active or system sleep with usb wakeup enabled, so usb root clock is fine with this situation; with the commit cf7f3f4fa9e5 ("clk: imx8mp: fix usb_root_clk parent"), this clock gate is changed to be for usb root clock, but usb root clock will be off while usb is suspended, so usb suspend clock will be gated too, this cause some usb functionalities will not work, so define this clock to be a shared clock gate to conform with the real HW status.

clk: imx8mp: Add audio shared gate According to the RM, the CCGR101 is shared for the following root clocks: - AUDIO_AHB_CLK_ROOT - AUDIO_AXI_CLK_ROOT - SAI1_CLK_ROOT - SAI2_CLK_ROOT - SAI3_CLK_ROOT - SAI5_CLK_ROOT - SAI6_CLK_ROOT - SAI7_CLK_ROOT - PDM_CLK_ROOT IMX8MP_CLK_AUDIO_ROOT is same as AUDIO_AHB_CLK_ROOT which can avoid break any users.

clk: imx: imx8mp: fix a53 cpu clock The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root signoff timing is 1Ghz, however the A53 core which sources from CCM root could run above 1GHz which voilates the CCM. There is a CORE_SEL slice before A53 core, we need configure the CORE_SEL slice source from ARM PLL, not A53 CCM clk root. The A53 CCM clk root should only be used when need to change ARM PLL frequency. Add arm_a53_core clk that could source from arm_a53_div and arm_pll_out. Configure a53 ccm root sources from 800MHz sys pll Configure a53 core sources from arm_pll_out Mark arm_a53_core as critical clk Reviewed-by: Jacky Bai <ping.bai@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

clk: imx8mp: tune the order of enet_qos_root_clk The enet_qos_root_clk takes sim_enet_root_clk as parent. When registering enet_qos_root_clk, it will be put into clk orphan list, because sim_enet_root_clk is not ready. When sim_enet_root_clk is ready, clk_core_reparent_orphans_nolock will set enet_qos_root_clk parent to sim_enet_root_clk. Because CLK_OPS_PARENT_ENABLE is set, sim_enet_root_clk will be enabled and disabled during the enet_qos_root_clk reparent phase. All the above are correct. But with M7 booted early and using enet, M7 enet feature will be broken, because clk driver probe phase disable the needed clks, in case M7 firmware not configure sim_enet_root_clk. And tune the order would also save cpu cycles.

clk: imx: imx8mp: add shared clk gate for usb suspend clk 32K usb suspend clock gate is shared with usb_root_clk, this shared clock gate was initially defined only for usb suspend clock, usb suspend clk is kept on while system is active or system sleep with usb wakeup enabled, so usb root clock is fine with this situation; with the commit cf7f3f4fa9e5 ("clk: imx8mp: fix usb_root_clk parent"), this clock gate is changed to be for usb root clock, but usb root clock will be off while usb is suspended, so usb suspend clock will be gated too, this cause some usb functionalities will not work, so define this clock to be a shared clock gate to conform with the real HW status.

clk: imx8mp: drop of_match_ptr from of_device_id table The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might be not relevant here).

clk: imx: add mcore_booted module paratemter Add mcore_booted boot parameter which could simplify AMP clock management. To i.MX8M, there is CCM(clock control Module) to generate clock root clock, anatop(analog PLL module) to generate PLL, and CCGR (clock gating) to gate clocks to peripherals. As below: anatop->ccm->ccgr->peripheral Linux handles the clock management and the auxiliary core is under control of Linux. Although there is per hardware domain control for CCGR and CCM, auxiliary core normally only use CCGR hardware domain control to avoid linux gate off the clk to peripherals and leave CCM ana anatop to Linux. Per NXP hardware design, because CCGR already support gate to peripherals, and clk root gate power leakage is negligible. So when in AMP case, we could not register the clk root gate.
