2021-02-15gpio: tegra: Fix irq_set_affinityDmitry Osipenko1-1/+2
The irq_set_affinity callback should not be set if parent IRQ domain doesn't present because gpio-tegra driver callback fails in this case, causing a noisy error messages on system suspend: Disabling non-boot CPUs ...

Tegra isn't capable of setting affinity per GPIO, affinity could be set only per GPIO bank, thus there is nothing to do for gpio-tegra in regards to CPU affinity without the parent IRQ domain.

2021-02-15selftests: gpio: rework and simplify test implementationKent Gibson4-288/+535
The GPIO mockup selftests are overly complicated with separate implementations of the tests for sysfs and cdev uAPI, and with the cdev implementation being dependent on tools/gpio and libmount. Rework the test implementation to provide a common test suite with a simplified pluggable uAPI interface. The cdev implementation utilises the GPIO uAPI directly to remove the dependence on tools/gpio. The simplified uAPI interface removes the need for any file system mount checks in C, and so removes the dependence on libmount. The rework also fixes the sysfs test implementation which has been broken since the device created in the multiple gpiochip case was split into separate devices.

Add support for the GPIO controller block in the R-Car V3U (R8A779A0) SoC, which is very similar to the block found on other R-Car Gen3 SoCs. However, this block has a new General Input Enable Register (INEN), whose reset state is to have all inputs disabled. Enable input for all available pins in probe and resume, to support the use of the General Input Register (INDT) for reading pin state at all times. This preserves backwards compatibility with other R-Car Gen3 SoCs, as recommended by the Hardware Manual.

2021-02-15gpio: rcar: Optimize GPIO pin state read on R-Car Gen3Geert Uytterhoeven1-5/+20
Currently, the R-Car GPIO driver treats R-Car Gen2 and R-Car Gen3 GPIO controllers the same. However, there exist small differences, like the behavior of the General Input Register (INDT): - On R-Car Gen1, R-Car Gen2, and RZ/G1, INDT only reflects the state of an input pin if the GPIO is configured for input, - On R-Car Gen3 and RZ/G2, INDT always reflects the state of the input pins. Hence to accommodate all variants, the driver does not use the INDT register to read the status of a GPIO line when configured for output, at the expense of doing 2 or 3 register reads instead of 1. Given register accesses are slow, change the .get() and .get_multiple() callbacks to always use INDT to read pin state on SoCs where this is supported.
