The 72116B0 has improved SDIO controllers that allow the max clock
rate to be increased from a max of 100MHz to a max of 150MHz. The
driver will need to get the clock and increase it's default rate
and override the caps register, that still indicates a max of 100MHz.
The new clock will be named "sdio_freq" in the DT node's "clock-names"
list. The driver will use a DT property, "clock-frequency", to
enable this functionality and will get the actual rate in MHz
from the property to allow various speeds to be requested.

Moshe Shemesh Says:
===================
1) Fix devlink lock in mlx5 devlink eswitch callbacks
Following the commit 14e426bf1a "devlink: hold the instance lock
during eswitch_mode callbacks" which takes devlink instance lock for all
devlink eswitch callbacks and adds a temporary workaround, this patchset
removes the workaround, replaces devlink API functions by devl_ API
where called from mlx5 driver eswitch callbacks flows and adds devlink
instance lock in other driver's path that leads to these functions.
While moving to devl_ API the patchset removes part of the devlink API
functions which mlx5 was the last one to use and so not used by any
driver now.
The patchset also remove DEVLINK_NL_FLAG_NO_LOCK flag from the callbacks
of port_new/port which are called only from mlx5 driver and the already
locked by the patchset as parallel paths to the eswitch callbacks using
devl_ API functions.
This patchset will be followed by another patchset that will remove
DEVLINK_NL_FLAG_NO_LOCK flag from devlink reload and devlink health
callbacks. Thus we will have all devlink callbacks locked and it will
pave the way to remove devlink mutex.

As part of the flows invoked by mlx5_devlink_eswitch_mode_set() get to
mlx5_rescan_drivers_locked() which can call mlx5e_probe()/mlx5e_remove
and register/unregister mlx5e driver ports accordingly. This can lead to
deadlock once mlx5_devlink_eswitch_mode_set() will use devlink lock.
Use devl_port_register/unregister() instead of
devlink_port_register/unregister() and add devlink instance locks in the
driver paths to this function to have it locked while calling devl_ API
function.
If remove or probe were called by module init or module cleanup flows,
need to lock devlink just before calling devl_port_register(), otherwise
it is called by attach/detach or register/unregister flow and we can
have the flow locked. Added flag to distinguish between these cases.
This will be used by the downstream patch to invoke
mlx5_devlink_eswitch_mode_set() with devlink locked.

part to eswitch_mode_set don't take devlink instance lock in any flow

This commit uses buckets for support bandwidth and clock rates. It
introduces a new function qcom_icc_bus_aggregate() to calculate the
aggregate average and peak bandwidths for every bucket, and also it
calculates the maximum value of aggregated average bandwidth across all
buckets.
The maximum aggregated average is used to calculate the final bandwidth
requests. And we can set the clock rate per bucket, we use SLEEP bucket
as default bucket if a platform doesn't enable the interconnect path
tags in DT binding; otherwise, we use WAKE bucket to set active clock
and use SLEEP bucket for other clocks. So far we don't use AMC bucket.

The current interconnect rpm driver uses a single aggregate bandwidth to
calculate the clock rates for both active and sleep clocks; therefore,
it has no chance to separate bandwidth requests for these two kinds of
clocks.
This patch studies the implementation from interconnect rpmh driver to
support multiple buckets. The rpmh driver provides three buckets for
AMC, WAKE, and SLEEP; this driver only needs to use WAKE and SLEEP
buckets, but we keep the same way with rpmh driver, this can allow us to
reuse the DT binding and avoid to define duplicated data structures.
This patch introduces two callbacks: qcom_icc_pre_bw_aggregate() is used
to clean up bucket values before aggregate bandwidth requests, and
qcom_icc_bw_aggregate() is to aggregate bandwidth for buckets.

This commit changes to use callback qcom_icc_xlate_extended(). This
is a preparation for population path tags from the interconnect DT
binding, it doesn't introduce functionality change for the existed DT
binding without path tags.
