I was debugging some gpio issues and I thought that the output of gpio debugfs was telling me the high or low level of the gpios with a '1' or a '0'. We saw a line like this though: gpio93 : in 4 2mA pull down and I started to think that there may be a gas leak in the building because '4' doesn't mean high or low, and other pins said '0' or '1'. It turns out, '4' is the function selection for the pinmux of the gpio and not the value on the pin. Reading code helps decipher what debugfs is actually saying. Add support to read the input or output pin depending on how the pin is configured so we can easily see the high or low value of the pin in debugfs. Now the output looks like gpio93 : in low func4 2mA pull down which clearly shows that the pin is an input, low, with function 4 and a 2mA drive strength plus a pull down.

To keep driver up to date we add generic pinctrl binding support, which covers the features used in this driver and has additional node properties that this SoC has compatibility, so enabling future implementations of these properties without the need to create new node properties in the device trees. The logic of this change maintain the old brcm legacy binding support in order to keep the ABI stable. Signed-off-by:

These are only available on the Meson8m2 SoC (which uses the same DesignWare Ethernet MAC as Meson8b). The "eth_tx_clk_50m" signal either provides a 50MHz clock for the RMII PHYs or the RGMII TX clock (as far as we know the frequency is controlled by the PRG_ETHERNET registers in the Ethernet MAC "glue" IP block).

Add Meson8m2 support to the existing Meson8 pinctrl driver. Since there are only very few changes (Meson8m2 has an extra signal on 10 CBUS pins, no other differences were found so far). Add the new compatible strings for Meson8m2 to the existing Meson8 driver so we don't have to duplicate the whole driver. Signed-off-by:

The Meson8m2 SoC is a variant of Meson8 with some updates from Meson8b (such as the Gigabit capable DesignWare MAC). It is mostly pin compatible with Meson8, only 10 (existing) CBUS pins get an additional function (four of these are Ethernet RXD2, RXD3, TXD2 and TXD3 which are required when the board uses an RGMII PHY). The AOBUS pins seem to be identical on Meson8 and Meson8m2. Signed-off-by:

The pinctrl-mcp23s08 driver doesn't provide a specific gpiospec of_xlate() function, causing the gpiolib-of's of_gpio_simple_xlate() function to be used instead, which takes the gpiospec's second cell as the flags specifier according to 'include/dt-bindings/gpio/gpio.h'. The pinctrl-mcp23s08 bindings document was mentioning that the flags were unused, which is not accurate because values in that second cell are indeed used by the gpiolib-of's of_gpio_simple_xlate() for configuring the gpio (e.g. its polarity). This way, replace the "flags currently unused" reference in the dt-bindings document with references to the appropriate files specifying the possible flag values and gpiospec description.

Newer versions of the firmware for the Qualcomm Datacenter Technologies QDF2400 restricts access to a subset of the GPIOs on the TLMM. To prevent older kernels from accidentally accessing the restricted GPIOs, we change the ACPI HID for the TLMM block from QCOM8001 to QCOM8002, and introduce a new property "gpios". This property is an array of specific GPIOs that are accessible. When an older kernel boots on newer (restricted) firmware, it will fail to probe. To implement the sparse GPIO map, we register all of the GPIOs, but fill in the data only for available GPIOs. This ensures that the driver cannot accidentally access an unavailable GPIO. The pinctrl-msm driver also scans the "gpios" property to determine which pins are available, and ensure that only those can be registered. Support for QCOM8001 is removed as there is no longer any firmware that implements it. Signed-off-by:
