Linus Torvalds 2f4c533499 SPDX update for 5.2-rc3, round 1
Here is another set of reviewed patches that adds SPDX tags to different
 kernel files, based on a set of rules that are being used to parse the
 comments to try to determine that the license of the file is
 "GPL-2.0-or-later" or "GPL-2.0-only".  Only the "obvious" versions of
 these matches are included here, a number of "non-obvious" variants of
 text have been found but those have been postponed for later review and
 analysis.
 
 There is also a patch in here to add the proper SPDX header to a bunch
 of Kbuild files that we have missed in the past due to new files being
 added and forgetting that Kbuild uses two different file names for
 Makefiles.  This issue was reported by the Kbuild maintainer.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.

Tony Lindgren 1cc54078d1 clk: ti: clkctrl: Fix clkdm_clk handling
We need to always call clkdm_clk_enable() and clkdm_clk_disable() even
the clkctrl clock(s) enabled for the domain do not have any gate register
bits. Otherwise clockdomains may never get enabled except when devices get
probed with the legacy "ti,hwmods" devicetree property.

Paul Walmsley f7df8c92b4 clk: sifive: restrict Kconfig scope for the FU540 PRCI driver
Restrict Kconfig scope for SiFive clock and reset IP block drivers
such that they won't appear on most configurations that are unlikely
to support them.  This is based on a suggestion from Pavel Machek
<pavel@ucw.cz>.  Ideally this should be dependent on
CONFIG_ARCH_SIFIVE, but since that Kconfig directive does not yet
exist, add dependencies on RISCV or COMPILE_TEST for now.

Linus Torvalds 815d469d8c One more patch to remove io.h from clk-provider.h. We used to need this
include when we had clk_readl() and clk_writel(), but those are gone now
 so this patch pushes the dependency out to the users of clk-provider.h.

Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

Stephen Boyd 1a079560b1 clk: Cache core in clk_fetch_parent_index() without names
If a clk has specified parents via clk_hw pointers it won't specify the
globally unique names for the parents. Without the unique names, we
can't fallback to comparing them against the name of the 'parent'
pointer here. Therefore, do a pointer comparison against the clk_hw
pointers too and cache the clk_core structure if they match. This fixes
parent lookup code for clks that only specify clk_hw pointers and
nothing else, like muxes that are purely inside a clk controller.

Similarly, if the parent pointer isn't cached after trying to match
clk_core or clk_hw pointers, lookup the pointer from DT or via clkdev
lookups instead of relying purely on the globally unique clk name match.
This should allow us to move away from having to specify global names
for clk parents entirely.

While we're in the area, add some comments so it's clearer what's going
on. The if statements don't lend themselves to much clarity in their raw
form.

The operations of pfdv2 gate_bit/valid_bit are incorrect,
they are defined as u8 for bit offset, but gate_bit is
actually assigned as mask which could be 32 bit long and
it causes overflow, and vld_bit is assigned as bit offset
based on incorrect gate_bit value, it causes incorrect

Stephen Boyd 90b6c5c73c clk: Remove CLK_IS_BASIC clk flag
This flag was historically used to indicate that a clk is a "basic" type
of clk like a mux, divider, gate, etc. This never turned out to be very
useful though because it was hard to cleanly split "basic" clks from
other clks in a system. This one flag was a way for type introspection
and it just didn't scale. If anything, it was used by the TI clk driver
to indicate that a clk_hw wasn't contained in the SoC specific clk
structure. We can get rid of this define now that TI is finding those
clks a different way.
