phy: broadcom: brcm-sata: Simplify with scoped for each OF child loop

2024-08-30T07:56:37+00:00

Use scoped for_each_available_child_of_node_scoped() when iterating over
device nodes to make code a bit simpler.

phy: broadcom: sata: fix Wvoid-pointer-to-enum-cast warning

phy: phy-brcm-sata: Allow configuration SATA AFE TX amplitude

2020-11-16T09:49:03+00:00

Read the 'brcm,tx-amplitude-millivolt' property from Device Tree and
propagate its value into the appropriate test transmit register to
change the TX amplitude.

phy: brcm-sata: Correct MDIO operations for 40nm platforms

2020-02-21T08:31:47+00:00

The logic to write to MDIO registers on 40nm platforms was wrong
because it would use the port number as an offset from the base address
rather than the bank address of the PHY. This is hardly noticeable
because the only programming we do is enabling SSC or not, which is not
really causing an observable functional change.

Correct that mistake by passing down the struct brcm_sata_port structure
down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do
the proper offsetting for 28nm, respectively 40nm platforms from there.
This means that brcm_sata_pcb_base() is now useless and is therefore
removed.

phy: brcm-sata: Implement 7216 initialization sequence

2020-01-08T07:28:06+00:00

7216 is a 16nm process chip with a slightly different version of the PHY
SerdDeS/AFE that requires a specific tuning sequence. Key on the
compatible string to perform that initialization.

phy: brcm-sata: Add BCM63138 (DSL) PHY init sequence

2018-09-25T10:40:08+00:00

The BCM63138 SATA PHY requires a special initialization sequence in
order to operate correctly, mostly tuning incorrect default values.
Implement that sequence and match the documented compatible string as an
entry point into that sequence.
