2023-08-11phy: qcom: qmp-ufs: add missing offsets to sm8150 configurationDmitry Baryshkov1-0/+2
The conversion commit 7559e7572c03 ("phy: Explicitly include correct DT includes") misses offsets configuration for sm8150 (most likely it was developed separately from the series adding HS G4 support and was not adapted for the sm8150/sm8250 configuration split). Add missing offsets to sm8150_ufsphy_cfg.

2023-07-17phy: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-01-17phy: qcom-qmp-ufs: Avoid setting HS G3 specific registersManivannan Sadhasivam1-7/+0
SM8350 default init sequence sets some PCS registers to HS G3, thereby disabling HS G4 mode. This has the effect on MPHY capability negotiation between the host and the device during link startup and causes the PA_MAXHSGEAR to G3 irrespective of device max gear. Due to that, the agreed gear speed determined by the UFS core will become G3 only and the platform won't run at G4. So, let's remove setting these registers for SM8350 as like other G4 compatible platforms. One downside of this is that, when the board design uses non-G4 compatible device, then MPHY will continue to run in the default mode (G4) even if UFSHCD runs in G3. But this is the case for other platforms as well.

2022-10-28phy: qcom-qmp-ufs: drop unused in-layout configurationJohan Hovold1-32/+10
The QMP UFS PHY driver does not use the "in-layout" configuration macro to configure registers that are typically accessed using "regs_layout" arrays (e.g. QPHY_START_CTRL) so drop this unused feature.

2022-09-24phy: qcom-qmp-ufs: Use dev_err_probe() to simplify codeYuan Can1-6/+3
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.
