2020-12-15drm/omap: dsi: pass vc and channel to various functionsTomi Valkeinen1-26/+28
To start fixing the issues related to channels and vcs described in the previous commit, pass vc and/or channel to various functions which will need it do properly handle different DSI channels and VCs. No functional changes.

2020-12-15drm/omap: dsi: rename 'channel' to 'vc'Tomi Valkeinen1-110/+110
The "channel" usage in omap dsi driver is confusing. We have three different "channels": 1) DSI virtual channel ID. This is a number from 0 to 3, included in the packet payload. 2) VC. This is a register block in the DSI IP. There are four of those blocks. A VC is a DSI "pipeline", with defined fifo settings, data source (cpu or dispc), and some other settings. It has no relation to the 1). 3) dispc channel. It's the "pipeline" number dispc uses to send pixel data. The previous patch handled the third case. To start fixing 1) and 2), we first rename all uses of 'channel' to 'vc', as in most of the cases that is the correct thing to use. However, in some places 1) and 2) have gotten mixed up (i.e. the code uses msg->channel when it should use vc), which will be fixed in the following patch. Note that mixing 1) and 2) currently is "fine", as at the moment we only support DSI peripherals with DSI virtual channel 0, and we always use VC0 to send data. So both 1) and 2) are always 0.

2020-12-15drm/omap: dsi: simplify VC handlingTomi Valkeinen1-36/+13
The VC handling has gotten quite tangled up. As the first step to clean it up, lets define that we only support a single DSI peripheral (which was really already the case), and we always use VC0 (define VC_DEFAULT 0) register block to send data to the peripheral. We can thus have a single mipi_dsi_device pointer and remove the for-loops which made passes over all the four VCs (just the first one was ever used).

2020-12-15drm/omap: dsi: send nop instead of page & columnTomi Valkeinen1-29/+17
The OMAP DSI command mode panel driver used to send page & column address before each frame update, and this code was moved into the DSI host driver when converting it to the DRM bridge model. However, it's not really required to send the page & column address before each frame. It's also something that doesn't really belong to the DSI host driver, so we should drop the code. That said, frame updates break if we don't send _something_ between the frames. A NOP command does the trick. It is not clear if this behavior is as expected from a DSI command mode frame transfer, or is it a feature/issue with OMAP DSI driver, or a feature/issue in the command mode panel used. Most likely this is related to the following from the DSI spec: "To enable PHY synchronization the host processor should periodically end HS transmission and drive the Data Lanes to the LP state. This transition should take place at least once per frame."

2020-12-15drm/omap: dsi: move TE GPIO handling into coreSebastian Reichel2-109/+140
In preparation for removing custom DSS calls from the DSI panel driver, this moves support for external tearing event GPIOs into the DSI host driver. This way tearing events are always handled in the core resulting in simplification of the panel drivers. The TE GPIO acquisition follows works in the same way as the exynos DSI implementation.

2020-12-15drm/omap: dsi: drop useless sync()Sebastian Reichel3-22/+0
The DSI sync() function only locks the bus and then releases it again. Currently the only invocation is directly before update(), which locks the bus anyways.
