The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

This allows drivers to be provided for clock generators, including

oscillators and PLLs. Devices can use a common clock API to request

a particular clock rate and check on available clocks. Clocks can

feed into other clocks in a tree structure, with multiplexers to

choose the source for each clock.

This provides very basic support for clocks on Intel SoCs. The driver

Much clock configuration in U-Boot is either set up by the FSP, or

set up by U-Boot itself but only statically. Thus the driver does not
|
|
support changing clock rates, only querying them.
