Sharing the same irqchip with multiple gpiochips is not a good
practice. For instance, when installing hooks, we change the state
of the irqchip. The initial state of the irqchip for the second
gpiochip to register is then disrupted.

This fix depends on the support of the drive-strength for the atmel pio4

In fact, this typo is present in several places in this file. It could
be worth fixing all those occurences in a single patch.

In atmel_shutdown() we call atmel_stop_rx() and atmel_stop_tx() functions.
Prevent the rx restart that is implemented in RS485 or ISO7816 modes when
calling atmel_stop_tx() by using the atomic information tasklet_shutdown
that is already in place for this purpose.

Hi,
This set of patches adds support for the ISO7816 standard. The USART devices in
Microchip SoCs have an ISO7816 mode. It allows to let the USART managing
the CLK and I/O signals of a smart card.

Sorry for the delay to answer. I changed my email filters. Unfortunately
there was a bug and I missed message from this mailing list...

Changes:
- v2: use atmel,drive-strength property instead of drive-strengh one
since it is not expressend in mA and there is no way to retrieve this
value at runtime.
- v1: https://www.spinics.net/lists/linux-gpio/msg27789.html
