2017-08-23drm/omap: fix i886 work-aroundTomi Valkeinen
7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.

2017-08-23drm/omap: fix analog tv-out modecheckTomi Valkeinen
omapdrm rejects all venc (analog tv-out) videomodes, due to somewhat strict checking of the values, making tv-out unusable. We only support two videomodes, one for PAL and one for NTSC, so instead of trying to check every field in the videomode struct, this patch makes the driver check only the pixel clock and the size of the display.

2017-08-16drm: omapdrm: Register omapdrm platform device in omapdss driverLaurent Pinchart
The omapdrm platform device is a virtual device created for the sole purpose of handling the omapdss/omapdrm driver split. It should eventually be removed. As a first step to ease refactoring move its registration from platform code to driver code. The omapdrm driver name must be changed internally to avoid probing both the device registered in platform code and the device registered in the omapdss driver, as that would otherwise break bisection.

2017-06-02drm/omap: fix YUV422 rotation with TILERTomi Valkeinen
TILER rotation with YUV422 pixelformats does not work at the moment. All other pixel formats work, because the pixelformat's pixel size is equal to tiler unit size (e.g. XR24's pixel size is 32 bits, and the TILER unit size that has to be used is 32 bits). For YUV422 formats this is not the case, as the TILER unit size has to be 32 bits, but the pixel size is 16 bits. The end result is OCP errors and sync losts. This patch adds the code to adjust the variables for YUV422 formats. We could make the code more generic by passing around the pixel format, rotation type, angle and the tiler unit size, which would allow us to do calculations without special case for YUV422. However, this would make the code more complex, and at least for now this is much more easier to handle with these two special cases for YUV422.
