| Subject: phy: qcom-qmp-usb: initialize PCS_USB registers |
| |
| From: Adrien Thierry <athierry@redhat.com> |
| |
| [ Upstream commit 2d3465a75c9f83684d17da6807423824bf260524 ] |
| |
| Currently, PCS_USB registers that have their initialization data in a |
| pcs_usb_tbl table are never initialized. Fix that. |
| |
| Fixes: fc64623637da ("phy: qcom-qmp-combo,usb: add support for separate PCS_USB region") |
