For legacy reasons, there are two configuration parameters that appear to describe the number of lanes a PHY has, even if "nlanes" was actually used for a different purpose. Replace them both with a new field simply named "lanes". Signed-off-by:

The nlanes configuration parameter is really the number of PHYs provided by this QMP block on MSM8996. Rename it accordingly. Signed-off-by:

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.

Convert the Renesas R-Car Gen2 USB PHY Device Tree binding documentation to json-schema. Add missing properties. Rename the device node from "usb-phy" to "usb-phy-controller", as it does not represent a USB PHY itself, and thus does not have a "#phy-cells" property. Rename the child nodes from "usb-channel" to "usb-phy", as these do represent USB PHYs. Drop the second example, as it doesn't add any value. Signed-off-by:

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.

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. Signed-off-by:

Commit 5e17b95d ("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.

Switch to using the device-managed of_iomap helper to avoid leaking memory on probe deferral and driver unbind. Note that this helper checks for already reserved regions and may fail if there are multiple devices claiming the same memory. Two bindings currently rely on overlapping mappings for the PCS region so fallback to non-exclusive mappings for those for now.
