drm/rockchip: hdmi support for rk3328

A patchset in state Mailinglist for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Fri, 16 Feb 2018 21:34:36 +0100

The rk3228/rk3229 and rk3328 socs started using a new type of hdmi-phy from Innosilicon that resides completely separate from the dw-hdmi block and gets accessed via mmio. Additionally the rk3328 dw-hdmi does not report the vendor-phy type but a different one instead, so add the possibility to override the phy type when the glue driver knows better than the ip block itself. I've put both the phy driver and dw-hdmi changes into one series just to showcase how everything comes together, but would of course still expect things to go through the separate phy and drm trees once deemed ready. So patches 1+2 are expected to go through the phy-tree and the rest should go through the drm tree. changes in v2: - phy: prevent overflow in tmdsclk calculation as reported by Martin Cerveny - phy: use unsigned long for all tmdsclk rate uses - phy: simplify tmds rate calculation - dropped patch exporting some dw-hdmi phy functions as a similar patch entered drm-misc already Heiko Stuebner (6): drm/bridge: dw-hdmi: allow overriding of phy-type reading drm/rockchip: dw_hdmi: Allow outputs that don't need output switching dt-bindings: allow optional phys in Rockchip dw_hdmi binding drm/rockchip: dw_hdmi: allow including external phys drm/rockchip: dw_hdmi: store rockchip_hdmi reference in phy_data object drm/rockchip: dw_hdmi: add dw-hdmi support for the rk3328 Zheng Yang (2): dt-bindings: add binding for Rockchip hdmi phy using an Innosilicon IP phy: add Rockchip Innosilicon hdmi phy .../bindings/display/rockchip/dw_hdmi-rockchip.txt | 3 + .../bindings/phy/phy-rockchip-inno-hdmi.txt | 42 + drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 4 +- drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 130 ++- drivers/phy/rockchip/Kconfig | 7 + drivers/phy/rockchip/Makefile | 1 + drivers/phy/rockchip/phy-rockchip-inno-hdmi.c | 1209 ++++++++++++++++++++ include/drm/bridge/dw_hdmi.h | 1 + 8 files changed, 1393 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/phy-rockchip-inno-hdmi.txt create mode 100644 drivers/phy/rockchip/phy-rockchip-inno-hdmi.c -- 2.15.1
