* pinctrl: samsung: fix leaked of_node referencesWen Yang2019-04-231-0/+1
| | | | | | | | | | | | | | | | | | | | | The call to of_find_compatible_node returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./drivers/pinctrl/samsung/pinctrl-exynos-arm.c:76:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 66, but without a corresponding object release within this function. ./drivers/pinctrl/samsung/pinctrl-exynos-arm.c:82:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 66, but without a corresponding object release within this function.

* pinctrl: stm32: introduce package supportAlexandre Torgue2019-04-232-11/+65
| | | | | | | | | | | | 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.

* pinctrl: add drive for I2C related pins on MT8183Zhiyong Tao2019-04-084-0/+131
| | | | | | | | | | | | | | | | | | | | | | | | | 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: Zhiyong Tao <zhiyong.tao@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| * pinctrl: sh-pfc: Introduce PINCTRL_SH_FUNC_GPIO helper symbolGeert Uytterhoeven2019-04-023-17/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pinctrl drivers for SuperH platforms use legacy function GPIOs. Currently this support is compiled in based on the SUPERH platform dependency, which hinders the introduction of compile-testing support for the affected pinctrl drivers. Introduce a new Kconfig symbol PINCTRL_SH_FUNC_GPIO, which is auto-selected when needed. This symbol in turn selects PINCTRL_SH_PFC_GPIO, to reduce the number of per-driver selects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Perform some basic sanity checks on all built-in pinmux tables when DEBUG is defined, to help catching bugs early. For now the following checks are included: - Check register and field widths in descriptors for config registers with variable-width fields, - Check relations between pin groups and functions: - All pin functions must refer to existing pin groups, - All pin groups must be referred to by a pin function, - Warn if a pin group is referred to by multiple pin functions (which is OK for backwards-compatibility aliases), - Provide suggestions for reducing table sizes: reserved fields of more than 3 bits can better be split in smaller subfields, as the storage need is proportional to the square of the width of the (sub)field, Note that a dummy non-matching entry is added to the DT match table for checking r8a7795es1_pinmux_info, as R-Car H3 ES1.0 is matched using soc_device_match() in r8a7795_pinmux_init(), instead of by the DT match table.

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.
