Ideally, what I prefer to see is a series of patches for all "essential" drivers
and the platform code that includes:
- one patch for each new binding
- one patch for each new driver
- one patch that hooks up arch/arm/mach-hpe/, MAINTAINERS
and any other changes to arch/arm/ other than dts
- one patch that adds the initial .dts and .dtsi files, with all the
devices added that have a valid binding, no need to split this
up any further
This should include everything you need to boot into an initramfs
shell, typically cpu, serial, timer, clk, pinctrl, gpio, irqchip. We will
merge these as a git branch in the soc tree.
In parallel, you can work with subsystem maintainers for the
"non-essential" drivers to review any other driver and binding,
e.g. drm/kms, network, i2c, pci, usb, etc. The patches for
the corresponding .dts additions also go through the soc tree,
but to make things simpler, you can send those in for a later
release.
