RTL9607C is a big endian MIPS CPU which is quite far from RTD series SoCs supported by realtek usb2 phy driver, but the phy initilization is found to be very indentical in most areas. Most of the code was based on the Realtek's usb driver from the GPL tarball in [1] and adjusted to fit into the realtek usb2 phy driver code format. The patch series was split into smaller patches that add/change something in the driver that are not exactly related to RTL9607C and that also helps for easier review. That also means, patch 5 depends on all the prior patches that come before it. USB2 PHY on RTL9607C is primarly used for its internal OHCI/EHCI controllers. [1] - https://github.com/jameywine/GPL-for-GP3000/blob/main/linux-5.10.x/arch/mips/rtl9607c/usb.c --- Changelog in v4: - Patch 2 - moved the le variations of read/write functions to Patch 5 where it is actually used because otherwise, it results in unused errors when only Patch 2 is applied. - updated the commit message to to point the reason for le32 wrappers around readl/writel. - Patch 3 - added "Reviewed by Krzysztof Kozlowski" - Patch 5 - updated the commit message to include the addition of little endian read/write functions from Patch 2. - Link to v3: https://lore.kernel.org/linux-phy/20260402154414.196012-1-adilov@disroot.org/ Changelog in v3: - Patch 2 - renamed phy read and functions to "rtk_usb2phy" to not collide with networking API functions - fixed the sparse warnings by creating intermidiate "tmp" variable and then pass it to writel - sligtly adjusted commit message to instead use "default read" not "default phy_read" - Patch 4 - added the check for reset_control_deassert() just in case - changed mdelay(5) to msleep(5) - changed dev_err and return combo with one dev_err_probe for phy_rst - Patch 5 - changed mdelay(10) under force_host_disconnect to msleep(10) - removed struct fields with false like force_host_disconnect and more in rtl9607_phy_cfg - Patch 6 - updated the #endif commend to now include MACH_REALTEK_RTL to reflect if on top - Link to v2: https://lore.kernel.org/linux-phy/20260327160638.15134-1-adilov@disroot.org/ Changelog in v2: - Patch 3 - removed the line about OHCI/EHCI controllers from description. - set the resets to false for RTD SoC devices and changed the commit message to reflect that. - Link to v1: https://lore.kernel.org/linux-phy/20260326193419.48419-1-adilov@disroot.org/ Rustam Adilov (6): phy: realtek: usb2: introduce vstatus/new_reg_req variables to driver data phy: realtek: usb2: introduce read and write functions to driver data dt-bindings: phy: realtek,usb2phy.yaml: extend for resets and RTL9607C support phy: realtek: usb2: introduce reset controller struct phy: realtek: usb2: add support for RTL9607C USB2 PHY phy: realtek: Make configs available for MACH_REALTEK_RTL .../bindings/phy/realtek,usb2phy.yaml | 25 ++- drivers/phy/realtek/Kconfig | 4 +- drivers/phy/realtek/phy-rtk-usb2.c | 183 ++++++++++++++++-- 3 files changed, 191 insertions(+), 21 deletions(-) -- 2.53.0 -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
