This patch series adds support for the Exynos USB 3.1 DRD combo phy, as found in Exynos 9 SoCs like Google GS101. It supports USB SS, HS and DisplayPort, but DisplayPort is out of scope for this series. In terms of UTMI+, this is very similar to the existing Exynos850 support in this driver. The difference is that it supports both UTMI+ (HS) and PIPE3 (SS). Firstly, there are some preparatory patches to convert this driver to using the clk_bulk and regulator_bulk APIs to simplify addition, while the bulk of the changes is around the SS part. Dependencies on other patches: While there is no compile or link time dependency, for USB to actually work this series also requires Peter's syscon changes from https://lore.kernel.org/all/20240614140421.3172674-1-peter.griffin@xxxxxxxxxx/ To: Vinod Koul <vkoul@xxxxxxxxxx> To: Kishon Vijay Abraham I <kishon@xxxxxxxxxx> To: Rob Herring <robh@xxxxxxxxxx> To: Krzysztof Kozlowski <krzk+dt@xxxxxxxxxx> To: Conor Dooley <conor+dt@xxxxxxxxxx> To: Peter Griffin <peter.griffin@xxxxxxxxxx> To: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> To: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> To: Alim Akhtar <alim.akhtar@xxxxxxxxxxx> To: Sam Protsenko <semen.protsenko@xxxxxxxxxx> Cc: Krzysztof Kozlowski <krzk@xxxxxxxxxx> Cc: Tudor Ambarus <tudor.ambarus@xxxxxxxxxx> Cc: Will McVicker <willmcvicker@xxxxxxxxxx> Cc: Roy Luo <royluo@xxxxxxxxxx> Cc: kernel-team@xxxxxxxxxxx Cc: linux-phy@xxxxxxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-samsung-soc@xxxxxxxxxxxxxxx Signed-off-by: André Draszik <andre.draszik@xxxxxxxxxx> Changes in v3: - drop patch 'phy: exynos5-usbdrd: use exynos_get_pmu_regmap_by_phandle() for PMU regs'. This is not needed anymore with Peter's syscon series mentioned above (Krzysztof). - drop those patches that have already been merged via https://lore.kernel.org/all/20240507-samsung-usb-phy-fixes-v1-0-4ccba5afa7cc@xxxxxxxxxx/ - update device tree binding 'reg-names' (Krzysztof) - use clk_bulk and regulator_bulk APIs throughout to simplify addition of gs101 support as preparatory patches - patch 1: add required but missing regulators - patch 4: * make the register access clock name(s) platform specific and avoid use of devm_clk_bulk_get_optional() as we want to be sure to have retrieved all required clocks * fix a whitespace issue * slightly rephrase commit message - patch 6: * set unused callback pointers to NULL in gs101_tunes[] * implement missing regulator support and enable power to phy before any register access * add more phy tunes * move PTS_UTMI_POSTINIT utmi phy tuning to before completion of POR sequence, as per datasheet * group gs101 related symbols closer to each other - Link to v2: https://lore.kernel.org/r/20240501-usb-phy-gs101-v2-0-ed9f14a1bd6d@xxxxxxxxxx Changes in v2: - avoid having nested else/if in the DT binding (Rob) - add missing bitfield.h include - Link to v1: https://lore.kernel.org/r/20240423-usb-phy-gs101-v1-0-ebdcb3ac174d@xxxxxxxxxx --- André Draszik (6): dt-bindings: phy: samsung,usb3-drd-phy: add gs101 compatible phy: exynos5-usbdrd: support isolating HS and SS ports independently phy: exynos5-usbdrd: convert core clocks to clk_bulk phy: exynos5-usbdrd: convert (phy) register access clock to clk_bulk phy: exynos5-usbdrd: convert Vbus supplies to regulator_bulk phy: exynos5-usbdrd: support Exynos USBDRD 3.1 combo phy (HS & SS) .../bindings/phy/samsung,usb3-drd-phy.yaml | 77 +- drivers/phy/samsung/phy-exynos5-usbdrd.c | 958 +++++++++++++++++---- include/linux/soc/samsung/exynos-regs-pmu.h | 4 + 3 files changed, 893 insertions(+), 146 deletions(-) --- base-commit: 6906a84c482f098d31486df8dc98cead21cce2d0 change-id: 20240423-usb-phy-gs101-abf3e172d1c4 Best regards, -- André Draszik <andre.draszik@xxxxxxxxxx>
