2018-11-02drm/panel: Add simple panel mode for the ARM RTSMLinus Walleij1-0/+30
Having failed any attempts at a more generic solution, I fall back to the very specific solution: define a simple panel for the ARM RTSM emulated platforms. I am doing this so we can convert all old users from the previous fbdev driver to the PL111 DRM driver. This works fine as far as I can test, provided the device tree for RTSM AEMv8 is augmented accordingly.

2018-10-29drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1Douglas Anderson1-7/+7
As far as I can tell the panel that was added in commit da50bd4258db ("drm/panel: simple: Add Innolux TV123WAM panel driver support") wasn't actually an Innolux TV123WAM but was actually an Innolux P120ZDG-BF1. As far as I can tell the Innolux TV123WAM isn't a real panel and but it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1. Let's unmosh. Here's my evidence: * Searching for TV123WAM on the Internet turns up a TI panel. While it's possible that an Innolux panel has the same model number as the TI Panel, it seems a little doubtful. Looking up the datasheet from the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm. * As far as I know, the patch adding the Innolux Panel was supposed to be for the board that's sitting in front of me as I type this (support for that board is not yet upstream). On the back of that panel I see Innolux P120ZDZ-EZ1 rev B1. * Someone pointed me at a datasheet that's supposed to be for the panel in front of me (sorry, I can't share the datasheet). That datasheet has the string "p120zdg-bf1" * If I search for "P120ZDG-BF1" on the Internet I get hits for panels that are 2160x1440. They don't have datasheets, but the fact that the resolution matches is a good sign. In any case, let's update the name and also the physical size to match the correct panel.

If the HPD signal isn't hooked up to this panel we need a 200 ms delay. In the datasheet this is shown as the maximum time that HPD will take to be asserted after power is given to the panel.

2018-10-29drm/panel: simple: Support panels with HPD where HPD isn't connectedDouglas Anderson1-2/+12
Some eDP panels that are designed to be always connected to a board use their HPD signal to signal that they've finished powering on and they're ready to be talked to. However, for various reasons it's possible that the HPD signal from the panel isn't actually hooked up. In the case where the HPD isn't hooked up you can look at the timing diagram on the panel datasheet and insert a delay for the maximum amount of time that the HPD might take to come up. Let's add support in simple-panel for this concept. At the moment we will co-opt the existing "prepare" delay to keep track of the delay and we'll use a boolean to specify that a given panel should only apply the delay if the "no-hpd" property was specified.

This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16. This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors. Depending on the variant, the PCB attached to the panel module either supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel itself.

otm8009a_enable() The backlight 1st update was in the otm8009a_prepare() function for a bad reason: backlight was not working in video mode and the otm8009a_prepare() is in command mode for the init sequence. As the backlight is now fixed (no low-power mode), it is good to put it back in the otm8009a_enable() function, avoiding also image glitches visible on some "slow" devices.

2018-05-18drm/panel: otm8009a: Fix backlight updatesPhilippe CORNU1-2/+16
Backlight updates was not working anymore since the good implementation of the DSI low-power mode in the DSI host driver. After a longer analysis, the backlight updates in DSI video mode require the DSI high- speed mode. Note: it is important to keep the DSI low-power mode for the rest of the driver as init sequence, sleep in/out... DSI commands work in low-power mode.

2018-05-18drm/panel: Remove drm_panel_detach() calls from all panel driversJyri Sarha9-9/+0
Remove all drm_panel_detach() calls from all panel drivers and update the kerneldoc for drm_panel_detach(). Setting the connector and drm to NULL when the DRM panel device is going away hardly serves any purpose. Usually the whole memory structure is freed right after the remove call. However, calling the detach function from the master DRM device, and setting the connector pointer to NULL, has the logic of marking the panel again as available for another DRM master to attach. The usual situation would be the same DRM master device binding again.

2018-04-30drm/panel: Enable DSI transactions on the RPi panel.Eric Anholt1-13/+1
It turns out that I had just mistaken what type of write the register writes were supposed to be, using DCS instead of generic long writes. Switching to transactions instead of using the atmel as a bridge also seems to resolve the sparkling pixels problem I've had.

2018-03-14drm/panel: rm68200: Add backlight dependencyArnd Bergmann1-0/+1
Like many other panel drivers, this one fails to build when backlight support is disabled: drivers/gpu/drm/panel/panel-raydium-rm68200.o: In function `rm68200_probe': panel-raydium-rm68200.c:(.text+0x14a): undefined reference to `devm_of_find_backlight' This adds the appropriate dependency. Note that while include/linux/backlight.h provides a stub inline when backlight support is not enabled, this isn't enough to deal with the case where backlight support is built as a module but the panel driver is built-in, in which case linking will still fail as above. One way to avoid this is to add a dependency such as this: depends on BACKLIGHT_CLASS_DEVICE || BACKLIGHT_CLASS_DEVICE=n but that is rather complex and misses the point that the panel support is mostly useless without backlight support.
