2018-10-03video/hdmi: Constify infoframe passed to the pack functionsVille Syrjälä
Let's make the infoframe pack functions usable with a const infoframe structure. This allows us to precompute the infoframe earlier, and still pack it later when we're no longer allowed to modify the structure. So now we end up with a _check()+_pack_only() or _pack() functions depending on whether you want to precompute the infoframes or not.

When using special phy handling operations we'll often need access to the rockchip_hdmi struct. As the chip-data that occupies the phy_data pointer initially gets assigned to the rockchip_hdmi struct, we can now re-use this phy_data pointer to hold the reference to the rockchip_hdmi struct and use this reference later on.

In some IP implementations the reading of the phy-type may be broken. One example are the Rockchip rk3228 and rk3328 socs that use a separate vendor-type phy from Innosilicon but still report the HDMI20_TX type. So allow the glue driver to force the vendor-phy for these cases.

This reverts commit 3510e7a7f91088159bfc67e8abdc9f9e77d28870. During the 4.19 merge window for drm-misc, two patches critical to supporting the display pipeline on the Allwinner R40 SoC were missed. They were applied later but missed the merge window deadline. As a result 4.19-rc1 kernel would crash on the R40 when it couldn't parse the new device tree structure. We ended up removing support for the R40 display pipeline for 4.19. Since the missing patches are already merged for 4.20, we can now revert the commit that removed support.

2018-09-26drm/fsl-dcu: Replace drm_dev_unref with drm_dev_putThomas Zimmermann
This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces.

2018-09-26MAINTAINERS: Move fsl-dcu driver to drm-misc treeStefan Agner
The driver is mostly in maintenance mode. Using drm-misc is a good fit and should make maintenance a bit easier. Signed-off-by: Stefan Agner <stefan@agner.ch> Acked-by: Sean Paul <sean@poorly.run> Link: https://patchwork.freedesktop.org/patch/msgid/20180926125034.4095-1-stefan@agner.ch
2018-09-26drm/mxsfb: Switch to drm_atomic_helper_commit_tail_rpmLeonard Crestez
The lcdif block is only powered on when display is active so plane updates when not enabled are not valid. Writing to an unpowered IP block is mostly ignored but can trigger bus errors on some chips. Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm and having the drm core ensure atomic_plane_update is only called while the crtc is active. This avoids having to keep track of "enabled" bits inside the mxsfb driver. This also requires handling the vblank event for disable from mxsfb_pipe_disable.

2018-09-26drm/mxsfb: Add PM_SLEEP supportLeonard Crestez
Since power to the lcdif block can be lost on suspend implement PM_SLEEP_OPS using drm_mode_config_helper_suspend/resume to save/restore the current mode.

2018-09-26drm/mxsfb: Add pm_runtime calls to pipe_enable/disableLeonard Crestez
Adding lcdif nodes to a power domain currently results in black/corrupted screens or hangs because power is not correctly enabled when required. Ensure power is on when display is active by adding pm_runtime_get/put_sync to mxsfb_pipe_enable/disable.

2018-09-26drm/mxsfb: Fix initial corrupt frame when activating displayLeonard Crestez
LCDIF will repeatedly display data from CUR_BUF and set CUR_BUF to NEXT_BUF when done. Since we are only ever writing to NEXT_BUF the display will show an initial corrupt frame. Fix by writing the FB paddr to both CUR_BUF and NEXT_BUF when activating the CRTC.

2018-09-26drm/mxsfb: Move axi clk enable/disable to crtc enable/disableLeonard Crestez
The main axi clk is disabled at the end of mxsfb_crtc_mode_set_nofb and immediately reenabled in mxsfb_enable_controller. Avoid this by moving the handling of axi clk one level up to mxsfb_crtc_enable. Do the same for mxsfb_crtc_disable for symmetry. This shouldn't have any functional effect.
