Subject: [PATCH v2 0/7] sandbox: add gpio support with libftdi1
Date: Mon, 15 Jan 2018 00:22:45 +0300	[thread overview]
Message-ID: <20180114212252.29682-1-antonynpavlov@gmail.com> (raw)

This patch series makes it possible to use FT2232H ACBUS[7:0]
pins as gpio pins from sandbox barebox.

There are ready-to-use FT2232H-based boards:

  * FT2232H-56Q Mini-Module (http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm#FT2232H-56_Mini)
  * FT2232 breakout board (http://dangerousprototypes.com/docs/FT2232_breakout_board)

The main goal of adding gpio functionality to sandbox barebox
is using it for connecting real i2c and spi devices to sandbox barebox.

Sample dts-file for at24 i2c eeprom and at25 spi flash is included.

Changes since v1 patch series (http://lists.infradead.org/pipermail/barebox/2017-October/031306.html):

  * rebase on top barebox v2017.12.0;
  * ds1307 i2c rtc driver works fine (i2c-gpio,scl-output-only is used);
  * parseopt_* functions are used for cmdline parsing.

Changes since RFC v1 patch series (http://lists.infradead.org/pipermail/barebox/2017-February/029106.html):

  * rebase on top barebox v2017.10.0;
  * libftdi cmdline options are added;
  * device tree support is added.
