* clk_fixed: call clkdom_dump() for verbose bootMitchell Horne2024-04-181-3/+4
| | | | | | | | | | | | | | | 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 defaultMitchell Horne2024-04-181-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We may attach several of these devices, but there is no meaningful information added to dmesg. For example: ofwbus0: <Open Firmware Device Tree> clk_fixed0: <Fixed clock> on ofwbus0 clk_fixed1: <Fixed clock> on ofwbus0 clk_fixed2: <Fixed clock> on ofwbus0 clk_fixed3: <Fixed clock> on ofwbus0 clk_fixed4: <Fixed clock> on ofwbus0 clk_fixed5: <Fixed clock> on ofwbus0 clk_fixed6: <Fixed clock> on ofwbus0 clk_fixed7: <Fixed clock> on ofwbus0 clk_fixed8: <Fixed clock> on ofwbus0 clk_fixed9: <Fixed clock> on ofwbus0 clk_fixed10: <Fixed clock> on ofwbus0 clk_fixed11: <Fixed clock> on ofwbus0 To reduce this noise, quiet the devices for by default. For verbose boot, the message will be emitted.

* clkdom_dump(): improve output textMitchell Horne2024-04-181-4/+14
| | | | | | | | | | | | | | | | 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.

* syscon_power: do reboot after shutdown_panic is executedAndriy Gapon2024-03-161-1/+3
| | | | | | | | | | A syscon_power instance can handle either poweroff or reboot, but not both. If the instance handles reboot then set its priority to be after shutdown_panic. This is to provide uniform experience with other platforms. (cherry picked from commit 5f7312a0d70c607afa9ce24ccd757321d043e02c)
* clk_fixed: reduce and clarify messages due to missing clk-frequencyMike Karels2023-09-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | 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: <Fixed clock> 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.

* clk: add call for nodes to get the programmed/decided frequency passed backAdrian Chadd2021-12-262-6/+31
| | | | | | | | | | | | | | | | | | | | | Summary: The existing call can only really be used for a node wishing to configure its parent, but as we don't pass in a pointer to the freq, we can't set it to what it would be for a DRY_RUN pass. So for clock nodes that wish to try setting parent frequencies to see which would be the best for its own target frequency, we really do need a way to call in and pass in a flag /and/ a pointer to freq so it can be updated for us as the clock tree is recursed through.

* Correctly handle nodes compatible with "syscon", "simple-bus".Michal Meloun2020-09-252-6/+22
| | | | | | | | | | | | | | | | Syscon can also have child nodes that share a registration file with it. To do this correctly, follow these steps: - subclass syscon from simplebus and expose it if the node is also "simple-bus" compatible. - block simplebus probe for this compatible string, so it's priority (bus pass) doesn't colide with syscon driver. While I'm in, also block "syscon", "simple-mfd" for the same reason. MFC after: 4 weeks Notes: svn path=/head/; revision=366156
