[PATCH 2/3] mailbox: imx: Add runtime PM callback to handle MU clocks

Some of i.MX8M SoCs have MU clock, they need to be managed in runtime to make sure the MU clock can be off in runtime, add runtime PM callback to handle MU clock. And on i.MX8MP, the MU clock is combined with power domain and runtime PM is enabled for the clock driver, during noirq suspend/resume

[PATCH 1/3] mailbox: imx: Add context save/restore for suspend/resume

From: Dong Aisheng For "mem" mode suspend on i.MX8 SoCs, MU settings could be lost because its power is off, so save/restore is needed for MU settings during suspend/resume. However, the restore can ONLY be done when MU settings are actually lost, for the scenario of settings NOT lost in

[PATCH 0/3] Handle mailbox clock/power management related issues

Current i.MX mailbox driver mainly supports 2 series i.MX SoCs with different architecture, one is for i.MX8X platforms with SCU inside, the other is for i.MX6/7/8M series without SCU. For i.MX8X, 2 types of MU are supported, one is for system IPC, such kind of MU has no clock/power assignment,

[PATCH 3/3] mailbox: imx: ONLY IPC MU needs IRQF_NO_SUSPEND flag

IPC MU has no power domain assigned and there could be IPC during noirq suspend phase, so IRQF_NO_SUSPEND flag is needed for IPC MU. However, for other MUs, they have power domain assigned and their power will be turned off during noirq suspend phase, but with IRQF_NO_SUSPEND set, their interrupts

Re: [PATCH] tcp: fix TCP socks unreleased in BBR mode

Hi Eric, I'm still trying to understand what you're saying before. Would this be better as following: 1) discard the tcp_internal_pacing() function. 2) remove where the tcp_internal_pacing() is called in the __tcp_transmit_skb() function. If we do so, we could avoid 'too late to give up pacing'.
