drm/msm: basic KMS driver for snapdragon The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>

This adds a compile-time check for ARCH_QCOM, and clarifies the Kconfig select statement so we don't even try it for other targets. The check for CONFIG_QCOM_MDT_LOADER can then go away, which also improves compile-time coverage and makes the code a little nicer to read.

drm/msm/mdp4: add LVDS panel support LVDS panel support uses the LCDC (parallel) encoder. Unlike with HDMI, there is not a separate LVDS block, so no need to split things into a bridge+connector. Nor is there is anything re-used with mdp5. Note that there can be some regulators shared between HDMI and LVDS (in particular, on apq8064, ext_3v3p), so we should not use the _exclusive() variants of devm_regulator_get().

drm/msm/dsi: Add PHY/PLL for 8x96 Extend the DSI PHY/PLL drivers to support the DSI 14nm PHY/PLL found on 8x96. These are picked up from the downstream driver. The PHY part is similar to the other DSI PHYs. The PLL driver requires some trickery so that one DSI PLL can drive both the DSIs (i.e, dual DSI mode). In the case of dual DSI mode. One DSI instance becomes the clock master, and other the clock slave. The master PLL's output (Byte and Pixel clock) is fed to both the DSI hosts/PHYs. When the DSIs are configured in dual DSI mode, the PHY driver communicates to the PLL driver using msm_dsi_pll_set_usecase() which instance is the master and which one is the slave. When setting rate, the master PLL also configures some of the slave PLL/PHY registers which need to be identical to the master's for correct dual DSI behaviour. There are 2 PLL post dividers that should have ideally been modelled as generic clk_divider clocks, but require some customization for dual DSI. In particular, when the master PLL's post-diviers are set, the slave PLL's post-dividers need to be set too. The clk_ops for these use clk_divider's helper ops and flags internally to prevent redundant code.
