* phy: brcm-sata: Correct MDIO operations for 40nm platformsFlorian Fainelli2020-02-211-83/+65
| | | | | | | | | | | | | | | | | | 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 sequenceFlorian Fainelli2020-01-081-0/+120
| | | | | | | | | 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. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

* phy: brcm-sata: Add BCM63138 (DSL) PHY init sequenceFlorian Fainelli2018-09-251-0/+70
| | | | | | | | | | 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.
