Subject: [PATCH 0/5] sandbox: add gpio support with libftdi1
Date: Tue, 10 Oct 2017 15:26:26 +0300 [thread overview]
Message-ID: <20171010122631.9421-1-antonynpavlov@gmail.com> (raw)
This patch series makes it possible to use FT2232H ACBUS[7:0]
pins as gpio pins from sandbox barebox.
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.
Alas bit-bang i2c via libftdi1 works too slow and ds1307 i2c rtc driver
does not work correctly.
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.
