2023-03-20phy: qualcomm: phy-qcom-eusb2-repeater: Convert to platform remove callback ↵Uwe Kleine-König1-5/+3
returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Introduce a config option for each QMP PHY driver now that the QMP PHY mega-driver has been split up into different modules. This allows kernel configurators to limit the binary size of the kernel by only compiling in the QMP PHY driver that they need. Leave the old config QCOM_QMP in place and make it into a menuconfig so that 'make olddefconfig' continues to work. Furthermore, set the default of the new Kconfig symbols to be QCOM_QMP so that the transition is smooth.

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.

Since now there is support for configuring the HS Rate B mode properly, let's move the register setting to tbls_hs_b struct for all SoCs. This allows the PHY to be configured in Rate A initially and then in Rate B if requested by the UFS driver.

Add separate tables_hs_g4 instance to allow the PHY driver to configure the PHY in HS G4 mode. The individual SoC configs need to supply the Rx, Tx and PCS register setting in tables_hs_g4 and the UFS driver can request the Hs G4 mode by calling phy_set_mode_ext() with submode set to UFS_HS_G4.

2023-01-13phy: Revert "phy: qualcomm: usb28nm: Add MDM9607 init sequence"Marijn Suijten1-13/+0
This reverts commit 557a28811c7e0286d3816842032db5eb7bb5f156. This commit introduced an init sequence from downstream DT [1] in the driver. As mentioned by the comment above the HSPHY_INIT_CFG macro for this sequence: /* * The macro is used to define an initialization sequence. Each tuple * is meant to program 'value' into phy register at 'offset' with 'delay' * in us followed. */ Instead of corresponding to offsets into the phy register, the sequence read by the downstream driver [2] is passed into ulpi_write [3] which crafts the address-value pair into a new value and writes it into the same register at USB_ULPI_VIEWPORT [4]. In other words, this init sequence is programmed into the hardware in a totally different way than downstream and is unlikely to achieve the desired result, if the hsphy is working at all. An alternative method needs to be found to write these init values at the desired location. Fortunately mdm9607 did not land upstream yet [5] and should have its compatible revised to use the generic one, instead of a compatible that writes wrong data to the wrong registers.
