Arnd Bergmann 7b7c176372 phy: brcm-sata: remove unused variable
The newly introduced calibrate function has a variable
that has never been used and needs to be removed to avoid
this harmless warning:

drivers/phy/broadcom/phy-brcm-sata.c: In function 'brcm_stb_sata_calibrate':
drivers/phy/broadcom/phy-brcm-sata.c:514:24: error: unused variable 'priv' [-Werror=unused-variable]

Florian Fainelli 3e507769d1 phy: brcm-sata: Implement calibrate callback
Implement the calibration callback to allow turning on the Clock-Data
Recovery module clamping when necessary, e.g: during failure to identify
a SATA hard drive from ahci_brcm.c::brcm_ahci_read_id.

Florian Fainelli af174c4956 phy: brcm-sata: Allow RX equalizer tuning
Parse the DT properties brcm,rxaeq-mode and brcm,rxaeq-value to
correctly configure the RX equalizer of the PHY. This may be required to
resolve specific signal integrity issues.

Florian Fainelli 6ec248fed5 phy: brcm-sata: Prepare for doing more tuning
Split the functional code in brcm_stb_sata_init() to a separate function
that actually does configure spread spectrum: brcm_stb_sata_ssc_init()
and make that function return void, since that function cannot fail.

Dan Carpenter d9c51f4c53 phy: brcm-sata: fix a timeout test in init
We want to timeout with try set to zero so this should be a pre-op
instead of post-op.
