2020-08-14iomap: constify ioreadX() iomem argument (as in generic implementation)Krzysztof Kozlowski2-2/+2
Patch series "iomap: Constify ioreadX() iomem argument", v3. The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not. It seems there is nothing really stopping all of them to take pointer to const. This patch (of 4): The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not.

2020-08-13drm/mcde: Enable the DSI link with displayLinus Walleij3-35/+47
The MCDE DSI link hardware which is modeled like a bridge in DRM, connected further to the panel bridge, creating a pipeline. We have been using the .pre_enable(), .enable(), .disable() and .post_disable() callbacks from the bridge to set this up in a chained manner: first the display controller goes online and then in successive order each bridge in the pipeline. Inside DRM it works like this: drm_atomic_helper_commit_tail() drm_atomic_helper_commit_modeset_enables() struct drm_crtc_helper_funcs .atomic_enable() struct drm_simple_display_pipe_funcs .enable() MCDE display enable call drm_atomic_bridge_chain_enable() struct drm_bridge_funcs .pre_enable() mcde_dsi_bridge_pre_enable() panel_bridge_pre_enable() struct drm_panel_funcs .prepare() struct drm_bridge_funcs .enable() mcde_dsi_bridge_enable() panel_bridge_enable() struct drm_panel_funcs .enable() A similar sequence is executed for disabling. Unfortunately this is not what the hardware needs: at a certain stage in the enablement of the display controller the DSI link needs to come up to support video mode, else something (like a FIFO flow) locks up the hardware and we never get picture. Fix this by simply leaving the pre|enable and post|disable callbacks unused, and establish two cross-calls from the display controller to bring up the DSI link at the right place in the display bring-up sequence and vice versa in the shutdown sequence. For command mode displays, it works just fine to also enable the display flow early. The only time we hold it back right now is in one-shot mode, on-demand display updates. When combined with the previous patch and some patches for the S6E63M0 display controller to support DSI mode, this gives working display on the Samsung GT-I8190 (Golden) phone. It has also been tested working on the Samsung GT-S7710 (Skomer) phone.

2020-08-13drm/mcde: Fix display pipeline restartLinus Walleij4-82/+133
To make sure that the MCDE is in a reasonable state during set-up, perform a reset by power cycling the block by dropping the on-chip regulator reference after probe. The display subsystem (DSS) has no dedicated reset line so dropping the EPOD regulator is the only real way of resetting it. We introduce code to enable and disable the regulator in the display enable/disable callbacks. We move the generic MCDE setup such as muxing of DPI signals and masking of interrupts to the display handling. When we drop the power to the whole display subsystem, not only MCDE but also the DSI links lose their state. Therefore we move the DSI block reset and hardware initialization code to the mcde_dsi_bridge_pre_enable() callback so this happens every time we start up the bridge, as we may have lost the power. We move the final disablement of the interrupts and clocks to the mcde_dsi_bridge_post_disable() callback rather than have it in the mcde_dsi_bridge_disable() callback, as some control messages may still be sent over the DSI host after the bridge has been shut down. This (together with a patch for the corresponding panel) makes the Samsung GT-S7710 successfully disable and re-enable its display, cutting all power while disabled and re-initializing the hardware when coming back up.
