H6 SoC has a "pio group withstand voltage mode" register (datasheet description), that needs to be used to select either 1.8V or 3.3V I/O mode, based on what voltage is powering the respective pin banks and is thus used for I/O signals. Add support for configuring this register according to the voltage of the pin bank regulator (if enabled). This is similar to the support for I/O bias voltage setting patch for A80 and the same concerns apply. See: commit 402bfb3c ("Support I/O bias voltage setting on A80") Signed-off-by:

A same SoC can be available in several packages. Differences between packages are only the numbers of available balls. In order not to write a driver for each new package, same driver (ex: pinctrl-stm32mp157.c) will be used. This patch introduces the "package" property for each pin. So on a same driver, it will be possible to indicate on which package the pin is available. The package information will be got from the device tree. Signed-off-by:

This patch provides the advanced drive for I2C used pins on MT8183. The detail strength specification description of the I2C pin: When E1=0/E0=0, the strength is 0.125mA. When E1=0/E0=1, the strength is 0.25mA. When E1=1/E0=0, the strength is 0.5mA. When E1=1/E0=1, the strength is 1mA. For I2C pins, there are existing generic driving setup and the above specific driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA driving adjustment in generic driving setup. But in specific driving setup, they can support 0.125/0.25/0.5/1mA adjustment. If we enable specific driving setup for I2C pins, the existing generic driving setup will be disabled. For some special features, we need the I2C pins specific driving setup. The specific driving setup is controlled by E1E0EN. So we need add extra vendor driving preperty instead of the generic driving property. We can add "mediatek,drive-strength-adv = <XXX>;" to describe the specific driving setup property. "XXX" means the value of E1E0EN. So the valid arguments of "mediatek,drive-strength-adv" are from 0 to 7. Signed-off-by:

Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver supports the board controller chip on the Lochnagar board. Lochnagar provides many pins which can generally be used for an audio function such as an AIF or a PDM interface, but also as GPIOs. Signed-off-by:

Our pinctrl drivers are consisting of some common code, and big pin tables that are SoC-specific. This is fine in most cases, but when you want to reduce the size of the particular kernel image, those big tables are, well, quite big. We haven't had the option to disable them in the past since they were hidden Kconfig options based on the SoC support. However, that granularity isn't great since we don't have one Kconfig option per-SoC, but rather one by family. Make those options selectable by the user so that they can disable it if needed, while keeping the current default to not change the standard case. Acked-by:

The sunxi pinctrl only implements the pin_config_group_set callback at the moment, whereas the gpiochip_generic_config function relies on pin_config_set. Rework the functions a little to support pin_config_set, and rely on it for pin_config_group_set. Signed-off-by:
