This RFC patch series adds board staging support for r8a7740/armadillo.
For now this supports only the frame buffer device for the on-board LCD.
The goal is to complete the move to ARM multiplatform kernels for all
shmobile platforms, and drop the existing board files
The board staging area was introduced last year to allow continuous
upstream in-tree development and integration of platform devices. It
helps developers integrate devices as platform devices for device
drivers that only provide platform device bindings. This in turn allows
for incremental development of both hardware feature support and DT
binding work in parallel.
This series consists of 4 parts:
- Patch 1 re-enables compilation of the board staging area, which was
disabled after a compile breakage, but has been fixed in the mean
- Path 2 moves initialization of staging board code to an earlier
moment, as currently it happens after unused PM domains are powered
- Patches 3 and 4 (hopefully) fix the existing kzm9d board staging
code, which was presumably broken by commit 9a1091ef0017c40a
("irqchip: gic: Support hierarchy irq domain."),
