phy: qcom-qusb2: Fix HSTX_TRIM tuning with fused value for SDM845

2018-11-21T07:43:58+00:00

Tune1 register on sdm845 is used to update HSTX_TRIM with fused
setting. Enable same by specifying update_tune1_with_efuse flag
for sdm845, otherwise driver ends up programming tune2 register.

phy: qcom-qusb2: Use HSTX_TRIM fused value as is

2018-11-21T07:43:58+00:00

Fix HSTX_TRIM tuning logic which instead of using fused value
as HSTX_TRIM, incorrectly performs bitwise OR operation with
existing default value.

scsi/ufs: qcom: Remove ufs_qcom_phy_*() calls from host

2018-09-26T07:39:37+00:00

The host makes direct calls into phy using ufs_qcom_phy_*()
APIs. These APIs are only defined for 20nm qcom-ufs-qmp phy
which is not being used by any architecture as yet. Future
architectures too are not going to use 20nm ufs phy.
So remove these ufs_qcom_phy_*() calls from host to let further
change declare the 20nm phy as broken.
Also remove couple of stale enum defines for ufs phy.

The -EPROBE_DEFER virus demands special case code to avoid printing
