Unfortunately there is no (public) documentation for this hardware. The best thing we have is the 3.10 vendor kernel, which unfortunately doesn't document most register bits (only a few are named there, the rest is all magic numbers). It is possible that this is a TranSwitch HDMI TX PHY based core, but this is pure speculation. Adding a driver for the HDMI TX PHY gets us one step closer to video output on these older SoCs. Changes since v1 at [0]: - add a reg property to the dt-bindings - parse the reg property (register offset) in the driver - update copyright year to 2021 (spotted by Vinod, thanks!) - drop "default ARCH_MESON" from the Kconfig entry [0] https://patchwork.kernel.org/project/linux-amlogic/cover/20210604190338.2248295-1-martin.blumenstingl@googlemail.com/ Martin Blumenstingl (2): dt-bindings: phy: Add the Amlogic Meson8 HDMI TX PHY bindings phy: amlogic: Add a new driver for the HDMI TX PHY on Meson8/8b/8m2 .../phy/amlogic,meson8-hdmi-tx-phy.yaml | 55 ++++++ drivers/phy/amlogic/Kconfig | 10 ++ drivers/phy/amlogic/Makefile | 1 + drivers/phy/amlogic/phy-meson8-hdmi-tx.c | 162 ++++++++++++++++++ 4 files changed, 228 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/amlogic,meson8-hdmi-tx-phy.yaml create mode 100644 drivers/phy/amlogic/phy-meson8-hdmi-tx.c -- 2.32.0 _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic
