2022-09-24phy: qcom-snps: Use dev_err_probe() to simplify codeYuan Can1-12/+6
In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs.

of_get_parent() As the of_get_parent() will increase the refcount of the node->parent and the reference will be discarded, so we should hold the reference with which we can decrease the refcount when done.

2022-09-20phy: qcom-qmp-combo: fix sc8280xp PCS_USB offsetJohan Hovold1-0/+1
The PCS_USB register block lives at an offset of 0x300 from the PCS region on SC8280XP so add the missing offset to avoid corrupting unrelated registers on runtime suspend. Note that this region should probably be described separately in the binding.

2022-09-20phy: rockchip: inno-dsidphy: Add support for rk3568Chris Morgan1-46/+158
Add support for the Rockchip RK3568 DSI-DPHY. Registers were taken from the BSP kernel driver and wherever possible cross referenced with the TRM. Refactor the code to allow the different compatible strings to set either a max 1GHz timing table (all existing hardware) or a max 2.5GHz timing table (the new RK356x). This works (for me) on both an RK3326 (PX30) and a new RK3566 device.

2022-09-20phy: qcom-qmp-usb: drop legacy DT workaroundJohan Hovold1-21/+6
Commit 5e17b95d9893 ("phy: qcom-qmp: Utilize fully-specified DT registers") added a workaround for legacy devicetrees which did not specify register regions for the second lane of some dual-lane PHYs. At the time, the only two dual-lane PHYs supported by mainline were "qcom,sdm845-qmp-usb3-phy" and "qcom,sdm845-qmp-ufs-phy" and they had been added to the binding less than six months before the binding was fixed. Presumably no one is using four-year old SDM845 dtbs with mainline anymore so drop the workaround for malformed devicetrees. In the unlikely event that anyone complains, we can consider reverting.
