Series | Fix SPICC and ILI9486 drivers | expand |
This patchset is trying to fix problems seen on S905X boards when interfacing with an ILI9486 equipped SPI panel. The color corruption and the performance issues are actually due to two different problems in the SPICC driver and in the ILI9486 tiny DRM driver. We try to fix both in the same patcheset to be able to correctly use the SPI panel again.
