Hi Linus,
here is the big bulk of GPIO changes for v4.18.

The one change hitting MFD has an ACK from the MFD

Mostly smallish cleanups.

This patch adds the initial support of Secure Digital Host Controller
Interface compliant controller - R11 found in some latest Spreadtrum
chipsets.
R11 is a variant based on SD v4.0 specification.
With this driver, mmc can be initialized, can be mounted, read and
written.

ADMA2 64-bit addressing support is divided into V3 mode and V4 mode.
So there are two kinds of descriptors for ADMA2 64-bit addressing
i.e. 96-bit Descriptor for V3 mode, and 128-bit Descriptor for V4
mode. 128-bit Descriptor is aligned to 8-byte.
For V4 mode, ADMA2 64-bit addressing is enabled vi
For SD host controller version 4.00 or later ones, there're two

Oh yes, sorry I didn't spot that. I'll drop it.

This patchset initially tracked only the utilization of RT rq. During
OSPM summit, it has been discussed the opportunity to extend it in order
to get an estimate of the utilization of the CPU.
- Patches 1,2 move pelt code in a dedicated file and remove some blank lines
- Patches 3-4 add utiliza

Now that we have both the dl class bandwidth requirement and the dl class
utilization, we can detect when CPU is fully used so we should run at max.
Otherwise, we keep using the dl bandwidth requirement to define the
utilization of the CPU

Similarly to what happens with rt tasks, cfs tasks can be preempted by dl
tasks and the cfs's utilization might no longer describes the real
utilization level.
Current dl bandwidth reflects the requirements to meet deadline when tasks are
enqueued but not the current utilization of the dl sched cla
schedutil governor relies on cfs_rq's util_avg to choose the OPP when cfs
tasks are running. When the CPU is overloaded by cfs and rt tasks, cfs tasks
are preempted by rt tasks and in this case util_avg reflects the remaining
capacity but not what cfs want to use. In such case, schedutil can select
The time spent under interrupt can be significant but it is not reflected
in the utilization of CPU when deciding to choose an OPP. Now that we have
access to this metric, schedutil can take it into account when selecting
the OPP for a CPU.

The utilization of the CPU by rt, dl and interrupts are now tracked with
PELT so we can use these metrics instead of rt_avg to evaluate the remaining
capacity available for cfs class.
scale_rt_capacity() behavior has been changed and now returns the remaining
capacity available for cfs instead of
interrupt and steal time are the only remaining activities tracked by
rt_avg. Like for sched classes, we can use PELT to track their average
utilization of the CPU. But unlike sched class, we don't track when
entering/leaving interrupt; Instead, we take into account the time spent
under interrupt c
Take into account rt utilization when selecting an OPP for cfs tasks in order
to reflect the utilization of the CPU.

We want to track rt_rq's utilization as a part of the estimation of the
whole rq's utilization. This is necessary because rt tasks can steal
utilization to cfs tasks and make them lighter than they are.
As we want to use the same load tracking mecanism for both and prevent
useless dependency betwee
