Marijn Suijten d60c471a86 phy: Revert "phy: qualcomm: usb28nm: Add MDM9607 init sequence" ... This reverts commit 557a28811c. 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.
