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.Fixes: fc0c209c147f ("clk: Allow parents to be specified without string names")

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
pfd clock gate status in clock tree, this patch fixes the
issue by assigning them as correct bit offset.Fixes: 9fcb6be3b6c9 ("clk: imx: add pfdv2 support")

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.Cc: Tero Kristo

The M10V of the Milbeaut SoCs has an on-chip controller that derive
mostly clocks from a single external clock, using PLLs, dividers,
multiplexers and gates. Since the PLLs have already been started and
will not stop / restart, they are fixed factor. The gates will be added
in later patch (all of the gates are off state now).Signed-off-by: Sugaya Taichi
