phy: constify of_phandle_args in xlate

2024-02-23T12:13:14+00:00

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args.  Make the argument
pointer to const for code safety and readability.

phy: lan966x: Add missing serdes mux entry

2024-01-24T05:54:29+00:00

According to the datasheet(Table 3-2: Port configuration) the serdes 2
(SD2) can be configured to run QSGMII or SGMII mode. Already the QSGMII
mode is supported in the serdes_muxes list  but was missing the SGMII mode.
In this mode the serdes is connected to the port 4.
Therefore add this entry in the list.

phy: sparx5-serdes: add skip_cmu_cfg check when configuring lanes

2023-05-08T11:43:01+00:00

Add a check for skip_cmu_cfg when configuring the serdes lane.  All
individual serdeses are reset upon first configuration. Resetting the
serdes involves reconfiguring it with preset values. The serdesmode is
required to determine the clock-providing CMU, therefore make sure the
serdes is not reconfigured if the serdesmode is not set.

phy: sparx5-serdes: remove power up of all CMUs

2023-05-08T11:43:01+00:00

CMUs should not be powered up by default anymore, so remove responsible
code.

phy: sparx5-serdes: power on CMUs individually

2023-05-08T11:43:01+00:00

Power on the CMU instance, that provides the clock for the serdes, given the
specified serdes mode and index. The CMU instance is looked up, using a
preset map of serdes mode and index to CMU index.

phy: sparx5-serdes: power down all CMUs by default

2023-05-08T11:43:01+00:00

All CMUs are powered up initially. This uses needless power. This patch
makes sure all CMUs are powered down by default. This involves
configuring a number reference clock and power-down registers of the
CMU.

Individual CMUs are later powered up, when the serdes lanes are
configured.

phy: sparx5-serdes: reorder CMU functions

Reorder CMU functions, as some of them are now required by the serdes
functions. No functional changes.

phy: sparx5-serdes: configure optimal quiet mode for serdes lanes

2023-05-08T11:43:01+00:00

All the serdes lanes of the sparx5 will transition between normal mode
and quiet mode, depending on activity. Make sure that the quiet mode is
configured optimally for all lanes initially. Although not much, this
will save a small amount of power.
