Some pin names are longer than 12 characters. 32 characters should be enough while consuming not too much space. Signed-off-by: Benedikt Niedermayr <benedikt.niedermayr@siemens.com>
This patch adds support for multiplexing pins via debugfs rather than access memory mapped pad-configuration registers. The debugfs pinmux offers the possbility to run mraa on iot2050 platforms as regular user instead of root by adjusting privileges on debugfs files. Bias settings are currently also configured by accessing pinmux. Unfortunatelly a proper upstream-like pinconf usage is currently not possible. Note: In case debugfs mux fails MRAA falls back to mmap mux. Signed-off-by: Benedikt Niedermayr <benedikt.niedermayr@siemens.com>
IOT2050-SM board was added into IOT2050 series, in contrast to existing variants, the IOT2050-SM board comes without a Arduino interfaces. Signed-off-by: Li Hua Qian <huaqian.li@siemens.com>

@huaqianli: Some fixes where pushed meanwhile here regarding debugfs due to device tree changes of the iot2050. ... so there is still some work todo... |

iot2050: Add support for the new IOT2050-SM variant
IOT2050-SM board was added into IOT2050 series, in contrast to existing
variants, the IOT2050-SM board comes without a Arduino interfaces.
iot2050: add debugfs pinmux support
This patch adds support for multiplexing pins via debugfs rather
than access memory mapped pad-configuration registers.
The debugfs pinmux offers the possbility to run mraa on iot2050
platforms as regular user instead of root by adjusting privileges
on debugfs files.
Bias settings are currently also configured by accessing pinmux.
Unfortunatelly a proper upstream-like pinconf usage is currently
not possible.
Note: In case debugfs mux fails MRAA falls back to mmap mux.
common: increase pin name size
Some pin names are longer than 12 characters.
32 characters should be enough while consuming not too
much space.
