ARM: SoC changes for v5.8

Browse Source 
One new platform gets added, the Realtek RTD1195, which is an older
 Cortex-a7 based relative of the RTD12xx chips that are already supported
 in arch/arm64. The platform may also be extended to support running
 32-bit kernels on those 64-bit chips for memory-constrained machines.
 
 In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
 an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
 released in 2016 as one of the last high-end 32-bit designs.
 
 There is ongoing cleanup for the integrator, tegra, imx, and omap2
 platforms, with integrator getting very close to the goal of having
 zero code in arch/arm/, and omap2 moving more of the chip specifics
 from old board code into device tree files.
 
 The Versatile Express platform is made more modular, with built-in
 drivers now becoming loadable modules. This is part of a greater effort
 for the Android OS to have a common kernel binary for all platforms and
 any platform specific code in loadable modules.
 
 The PXA platform drops support for Compulab's pxa2xx boards that had
 rather unusual flash and PCI drivers but no known users remaining.
 All device drivers specific to those boards can now get removed as
 well.
 
 Across platforms, there is ongoing cleanup, with Geert and Rob
 revisiting some a lot of Kconfig options.

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.

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

The IM-PD1 is an add-on logic module for the Integrator which
allows ARM(R) Ltd PrimeCells to be developed and evaluated.
The IM-PD1 can be found on the Integrator/PP2 platform.
To compile this driver as a module, choose M here: the
module will be called impd1.
