clk_fixed: call clkdom_dump() for verbose boot

2024-04-18T18:11:31+00:00

This is standard practice for clock drivers that register clocks
dynamically. Nothing else uses the CLK_DEBUG macro.

The result is that the name and frequency of the fixed clock is printed
for a verbose boot, which may aid in debugging.

clk_fixed: quiet by default

2024-04-18T18:11:31+00:00

We may attach several of these devices, but there is no meaningful
information added to dmesg. For example:

  ofwbus0: 
  clk_fixed0:  on ofwbus0
  clk_fixed1:  on ofwbus0
  clk_fixed2:  on ofwbus0
  clk_fixed3:  on ofwbus0
  clk_fixed4:  on ofwbus0
  clk_fixed5:  on ofwbus0
  clk_fixed6:  on ofwbus0
  clk_fixed7:  on ofwbus0
  clk_fixed8:  on ofwbus0
  clk_fixed9:  on ofwbus0
  clk_fixed10:  on ofwbus0
  clk_fixed11:  on ofwbus0

To reduce this noise, quiet the devices for by default. For verbose
boot, the message will be emitted.

clkdom_dump(): improve output text

2024-04-18T18:11:31+00:00

If the call to clknode_get_freq() returns an error (unlikely), report
this, rather than printing the error code as the clock frequency.

If the clock has no parent (e.g. a fixed reference clock), print "none"
rather than "(NULL)(-1)". This is a more human-legible presentation of the
same information.

clk_fixed: reduce and clarify messages due to missing clk-frequency

2023-09-21T21:14:47+00:00

The current dts for Raspberry 3B+ and 4B have 2 disabled fixed-clock
nodes which have no clock-frequency value.  Such nodes are non-standard.
This results in about 150 messages during autoconfiguration:

    clk_fixed2:  disabled on ofwbus0
    clk_fixed2: Cannot FDT parameters.
    device_attach: clk_fixed2 attach returned 6

Defensively check for clock-frequency in the probe routine, and if
none, return an error with a more direct error message (1 line per
occurrence, 50 lines total):

    clk_fixed2: clock-fixed has no clock-frequency

Based on a patch by manu.

Include opt_platform.h to get the FDT definition and only include FDT
headers when FDT is defined.

Remove unneeded headers from clk_link.c

There is no OFW/FDT specific code in this file so the ofw headers can
be removed.
