The Lantiq PEF2256 is a framer and line interface component designed to fulfill all required interfacing between an analog E1/T1/J1 line and the digital PCM system highway/H.100 bus. This kind of component can be found in old telecommunication system. It was used to digital transmission of many simultaneous telephone calls by time-division multiplexing. Also using HDLC protocol, WAN networks can be reached through the framer. This pinmux support handles the pin muxing part (pins RP(A..D) and pins XP(A..D)) of the PEF2256. Signed-off-by:

A framer is a component in charge of an E1/T1 line interface. Connected usually to a TDM bus, it converts TDM frames to/from E1/T1 frames. It also provides information related to the E1/T1 line. The framer framework provides a set of APIs for the framer drivers (framer provider) to create/destroy a framer and APIs for the framer users (framer consumer) to obtain a reference to the framer, and use the framer. This basic implementation provides a framer abstraction for: - power on/off the framer - get the framer status (line state) - be notified on framer status changes - get/set the framer configuration Signed-off-by:

Rework for_each_requested_gpio_in_range() to use the new helper to retrieve a dynamically allocated copy of the descriptor label and free it at the end of each iteration. We need to leverage the CLASS()' destructor to make sure that the label is freed even when breaking out of the loop. Signed-off-by:

gpiochip_is_requested() not only has a misleading name but it returns a pointer to a string that is freed when the descriptor is released. Provide a new helper meant to replace it, which returns a copy of the label string instead. Signed-off-by:

The pinconf-groups debugfs file dumps each valid configuration item of all pin groups. Some platforms and devices may have pin groups which cannot be accessed, according to commit 691bf5d5 ("pinctrl: qcom: Don't allow protected pins to be requested"). Fail for each configuration item of an invalid pin group by checking the GPIO chip's valid mask. The validity of the pin group cannot be checked in the generic pinconf dump (function "pinconf_generic_dump_one"), as it does not directly interact with the gpiochip or the pinmux callbacks (which would give it access to the request callback). Instead, an entry contains the ID and name of the pingroup with no properties when all items fail. Signed-off-by:
