2022-04-26drm/sun4i: Remove obsolete references to PHYS_OFFSETSamuel Holland1-3/+0
commit b4bdc4fbf8d0 ("soc: sunxi: Deal with the MBUS DMA offsets in a central place") added a platform device notifier that sets the DMA offset for all of the display engine frontend and backend devices. The code applying the offset to DMA buffer physical addresses was then removed from the backend driver in commit 756668ba682e ("drm/sun4i: backend: Remove the MBUS quirks"), but the code subtracting PHYS_OFFSET was left in the frontend driver. As a result, the offset was applied twice in the frontend driver. This likely went unnoticed because it only affects specific configurations (scaling or certain pixel formats) where the frontend is used, on boards with both one of these older SoCs and more than 1 GB of DRAM. In addition, the references to PHYS_OFFSET prevent compiling the driver on architectures where PHYS_OFFSET is not defined.

D1 has a TCON TOP, so its quirks are similar to those for the R40 TCONs. While there are some register changes, the part of the TCON TV supported by the driver matches the R40 quirks, so that quirks structure can be reused. D1 has the first supported TCON LCD with a TCON TOP, so the TCON LCD needs a new quirks structure. D1's TCON LCD hardware supports LVDS; in fact it provides dual-link LVDS from a single TCON. However, it comes with a brand new LVDS PHY. Since this PHY has not been tested, leave out LVDS driver support for now.

Newly introduced mode_set callback in engine structure is a much better place for setting mixer output size and interlace mode for the following reasons: 1. Aforementioned properties change only when mode changes, so it's enough to be set only once per mode set. Currently it's done whenever properties of primary plane are changed. 2. It's assumed that primary plane will always cover whole screen. While this is true most of the time, it's not always. DE2/3 planes are universal and mostly equal in functionality.

2022-04-26drm/ssd130x: Make ssd130x_remove() return voidUwe Kleine-König3-5/+5
This function returns zero unconditionally, so there isn't any benefit of returning a value. Make it return void to be able to see at a glance that the return value of ssd130x_i2c_remove() is always zero. This patch is a preparation for making i2c remove callbacks return void.

2022-04-26drm/i915/fbc: Consult hw.crtc instead of uapi.crtcVille Syrjälä1-1/+1
plane_state->uapi.crtc is not what we want to be looking at. If bigjoiner is used hw.crtc is what tells us what crtc the plane is supposedly using. Not an actual problem on current hardware as the only FBC capable pipe (A) can't be a bigjoiner slave and thus uapi.crtc==hw.crtc always here. But when we get more FBC instances this will become actually important.
