Merge tag 'versatile-v5.8-1' of... 

Merge tag 'versatile-v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into arm/soc

Versatile family updates for the v5.8 kernel series:

- Drop unneeded SPARSE_IRQ selection.
- Drop a bunch of other unneed selections already
  selected by multiplatform overall Kconfig.
- Remove the dead sched_clock() code in plat-versatile.
- Drop the mapping of the IB2 registers. Now handled
  by the PL11x DRM driver.
- Add a bus driver for the Integrator/AP logic modules,
  along with its device tree bindings.
- Retire the LM and IM-PD1 boardfile code: we now handle
  this with the bus driver and device tree.
- Select some Integrator features needed for boot in
  its KConfig.
- Fix a minor MAINTAINERS entry.

title: Integrator/AP Logic Module extension bus



maintainers:

  - Linus Walleij <linusw@kernel.org>



description: The Integrator/AP is a prototyping platform and as such has a

  site for stacking up to four logic modules (LM) designed specifically for

  use with this platform. A special system controller register can be read to

  determine if a logic module is connected at index 0, 1, 2 or 3. The logic

  module connector is described in this binding. The logic modules per se

  then have their own specific per-module bindings and they will be described

  as subnodes under this logic module extension bus.

    description: Nodes on the Logic Module bus represent logic modules

      and are named with bus. The first module is at 0xc0000000, the second

      at 0xd0000000 and so on until the top of the memory of the system at

      0xffffffff. All information about the memory used by the module is

      in ranges and dma-ranges.
