Subject: [PATCH v2 0/2] reset: Basic reset controller

Hello,

This is v2 of the basic reset controller, which addresses the points that
Philipp made. See the individual patches for changelogs. The original cover
letter follows:

In the Aspeed SoCs we have some reset registers spread out in various parts of
the soc: in the system controller IP, as well as other peripherals. I need to be
able to deassert those resets before other drivers work.

In writing a driver to do this I realised it was very generic. So instead I've
sent a generic driver that can be used by the device tree to clear reset lines
described by single bits in a register.

I've tested this driver on our SoC to release the UART reset.

  dt-bindings: reset: Add bindings for basic reset controller
  reset: Add basic single-register reset driver
