Hi, Here is a set of patches to allow the phy framework consumers to test and apply runtime configurations. This is needed to support more phy classes that require tuning based on parameters depending on the current use case of the device, in addition to the power state management already provided by the current functions. A first test bed for that API are the MIPI D-PHY devices. There's a number of solutions that have been used so far to support these phy, most of the time being an ad-hoc driver in the consumer. That approach has a big shortcoming though, which is that this is quite difficult to deal with consumers integrated with multiple variants of phy, of multiple consumers integrated with the same phy. The latter case can be found in the Cadence DSI bridge, and the CSI transceiver and receivers. All of them are integrated with the same phy, or can be integrated with different phy, depending on the implementation. I've looked at all the MIPI DSI drivers I could find, and gathered all the parameters I could find. The interface should be complete, and most of the drivers can be converted in the future. The current set converts two of them: the above mentionned Cadence DSI driver so that the v4l2 drivers can use them, and the Allwinner MIPI-DSI driver. Let me know what you think, Maxime Maxime Ripard (10): phy: Add MIPI D-PHY mode phy: Add configuration interface phy: Add MIPI D-PHY configuration options phy: dphy: Add configuration helpers sun6i: dsi: Convert to generic phy handling phy: Move Allwinner A31 D-PHY driver to drivers/phy/ drm/bridge: cdns: Remove mode_check test drm/bridge: cdns: Separate DSI and D-PHY configuration phy: Add Cadence D-PHY support drm/bridge: cdns: Convert to phy framework drivers/gpu/drm/bridge/cdns-dsi.c | 506 ++------------------- drivers/gpu/drm/sun4i/Kconfig | 3 +- drivers/gpu/drm/sun4i/Makefile | 5 +- drivers/gpu/drm/sun4i/sun6i_mipi_dphy.c | 292 +------------ drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c | 30 +- drivers/gpu/drm/sun4i/sun6i_mipi_dsi.h | 17 +- drivers/phy/Kconfig | 9 +- drivers/phy/Makefile | 2 +- drivers/phy/allwinner/Kconfig | 12 +- drivers/phy/allwinner/Makefile | 1 +- drivers/phy/allwinner/phy-sun6i-mipi-dphy.c | 322 +++++++++++++- drivers/phy/cadence/Kconfig | 13 +- drivers/phy/cadence/Makefile | 1 +- drivers/phy/cadence/cdns-dphy.c | 499 +++++++++++++++++++++- drivers/phy/phy-core-mipi-dphy.c | 160 +++++++- drivers/phy/phy-core.c | 62 +++- include/linux/phy/phy-mipi-dphy.h | 247 ++++++++++- include/linux/phy/phy.h | 49 ++- 18 files changed, 1455 insertions(+), 775 deletions(-) delete mode 100644 drivers/gpu/drm/sun4i/sun6i_mipi_dphy.c create mode 100644 drivers/phy/allwinner/phy-sun6i-mipi-dphy.c create mode 100644 drivers/phy/cadence/Kconfig create mode 100644 drivers/phy/cadence/Makefile create mode 100644 drivers/phy/cadence/cdns-dphy.c create mode 100644 drivers/phy/phy-core-mipi-dphy.c create mode 100644 include/linux/phy/phy-mipi-dphy.h base-commit: 5b394b2ddf0347bef56e50c69a58773c94343ff3 -- git-series 0.9.1
