Hi, This series enables simple framebuffer support on Google Pixel 6 and Pixel 6 Pro. Even if simple-framebuffer is deprecated and DRM should be used instead, having it available in DT is beneficial for several reasons at this point in time (the phone uses an OLED display): * energy consumption goes down significantly, as it changes from white (as left by bootloader) to black (linux console), and we generally don't run out of battery anymore when plugged into a USB port * less of a burn-in effect I assume * phone stays cooler due to reduced energy consumption by display Since Pixel 6 and Pixel 6 Pro use a different resolution display, this is the time to separate them into their respective DTs, and provide one for each of them. There are other differences between the two, like battery design capacity, but they don't matter at this stage due to incomplete upstream support. * dependency note * Due to the renaming of the gs101-oriole.dts, this series will conflict with any pending patches touching the same file. I have therefore based this series on top of my USB series from https://lore.kernel.org/r/20241203-gs101-phy-lanes-orientation-dts-v2-0-1412783a6b01@xxxxxxxxxx Please let me know if I should do something different. * dependency note end * For those who want to try this out: The stock bootloader disables the decon hardware trigger before jumping to Linux, preventing framebuffer updates from reaching the display. We have added a work-around in our Yocto BSP layer for the time being (until a proper display exists upstream). An alternative might be to port and use uniLoader from https://github.com/ivoszbg/uniLoader, as seems to be done for some other Exynos platforms.
