2021-08-11pinctrl: Add Intel Keem Bay pinctrl driverLakshmi Sowjanya D
About Intel Keem Bay: ------------------- Intel Keem Bay is a computer vision AI accelerator SoC based on ARM CPU. Documentation of Keem Bay: Documentation/vpu/vpu-stack-overview.rst. Pinctrl IP: ---------- The SoC has a customised pinmux controller IP which controls pin multiplexing and configuration. Keem Bay pinctrl IP is not based on and have nothing in common with the existing pinctrl drivers. The registers used are incompatible with the existing drivers, so it requires a new driver. Add pinctrl driver to enable pin control support in the Intel Keem Bay SoC. Co-developed-by: Vineetha G. Jaya Kumaran <vineetha.g.jaya.kumaran@intel.com> Signed-off-by: Vineetha G.

2021-03-25pinctrl: PINCTRL_ROCKCHIP should depend on ARCH_ROCKCHIPGeert Uytterhoeven
The Rockchip GPIO and pin control modules are only present on Rockchip SoCs. Hence add a dependency on ARCH_ROCKCHIP, to prevent asking the user about this driver when configuring a kernel without Rockchip platform support. Note that before, the PINCTRL_ROCKCHIP symbol was not visible, and automatically selected when needed. By making it tristate and user-selectable, it became visible for everyone.

2019-05-10pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driverAmelie Delaunay
This patch adds pinctrl/GPIO driver for STMicroelectronics Multi-Function eXpander (STMFX) GPIO expander. STMFX is an I2C slave controller, offering up to 24 GPIOs. The driver relies on generic pin config interface to configure the GPIOs. Signed-off-by: Amelie Delaunay <amelie.delaunay@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Depending on MACH_INGENIC prevent us from creating a generic kernel that works on more than one MIPS board. Instead, we just depend on MIPS being set. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-08-29pinctrl: ingenic: Merge GPIO functionalityPaul Cercueil
Merge the code of the gpio-ingenic driver into the pinctrl-ingenic driver. The reason behind this, is that the same hardware block handles both pin config / muxing and GPIO. ingenic_gpio_probe() have been marked as __init, but for the most part, the code is the exact same as what it was in the gpio-ingenic driver.
