    drm/tegra: dc: Use direct offset to plane registers · 1087fac1
    Thierry Reding authored
    Traditionally, windows were accessed indirectly, through a register
    selection window that required a global register to be programmed with
    the index of the window to access. Since the global register could be
    written from modesetting functions as well as the interrupt handler
    concurrently, accesses had to be serialized using a lock. Using direct
    accesses to the window registers the lock can be avoided.
