Subject: [PATCH v6 0/9] Raspberry Pi miniuart support
Date: Tue, 15 Jan 2019 06:44:00 +0100	[thread overview]
Message-ID: <cover.cea99e013da63859278229c6e1566362a1800ff4.1547530950.git-series.r.czerwinski@pengutronix.de> (raw)

This patch series adds support for the raspberry pi miniuart (also called
aux-uart) to barebox.
With this series the miniuart overlay is no longer necessary to start barebox on
Raspberry Pi 3.

v6:
- Remove leftover val and missing fixup of the AUX Clock defines

v5:
- Add defines for register and base values
  from Sascha Hauer and Roland Hieber

v4:
- Fix indentation for compatible
- Fix __maybe_unused annnotation for rpi_drvdata missed in v3
  from Sascha Hauer

v3:
- Fix Indentation
  from Oleksij Rempel and Sascha Hauer

v2:
- Move console clock initialization into board core
- Retrieve the core clock frequency for the miniuart from the firmware
- Double the clock frequency in the ns16550 rpi init function instead of
  during initialization
  from Lucas Stach

Rouven Czerwinski (9):
  ARM: rpi: fix typo in rpi-common.c
  ARM: rpi: move clks into board specific rpi-common
  ARM: rpi: retrieve miniuart clock from firmware
  serial_ns16550: handle default reg-io-width
  serial_ns16550: add raspberry pi compatible and init
  ARM: rpi: add NS16550 support
  ARM: rpi: choose miniuart as stdout
  doc: bcm283x: remove miniuart overlay instruction
  ARM: rpi: use defines for uart bases
