2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

2018-07-24pinctrl: samsung: Add dedicated compatible for S5Pv210 wakeup interruptsKrzysztof Kozlowski
The S5Pv210 external wakeup interrupts differ from Exynos therefore separate compatible is needed. Duplicate existing flavor specific data from exynos4210_wkup_irq_chip and add new compatible for S5Pv210. At this point this new compatible does not bring anything new and works exactly as existing "samsung,exynos4210-wakeup-eint".

2018-07-24pinctrl: samsung: Document hidden requirement about one external wakeupKrzysztof Kozlowski
ARMv7 hardware (S5Pv210 and Exynos SoCs) provides only 32 external interrupts which can wakeup device from deep sleep modes. On S5Pv210 these are gph0-gph3. On all ARMv7 Exynos designs these are gpx0-gpx3. There is only one 32-bit register for controlling the external wakeup interrupt mask (masking and unmasking waking capability of these interrupts). This lead to implementation in pinctrl driver and machine code which was using static memory for storing the mask value and not caring about multiple devices of pin controller... because only one pin controller device will be handling this. Since each pin controller node in Device Tree maps onto one device, this corresponds to hidden assumption in parsing the Device Tree: external wakeup interrupts can be defined only once. Make this assumption an explicit requirement. ARMv8 Exynos5433 and Exynos7 bring additional 32 external wakeup interrupts (up to 64 total, banks gpa0-gpa3 and gpf1-gpf5) and another 32-bit wide register for controlling them. Existing code does not support it but anyway these additional interrupts will be belonging to the same pin controller device/node.

2014-07-11pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodesTomasz Figa
One of remaining limitations of current pinctrl-samsung driver was the inability to parse multiple pinmux/pinconf group nodes grouped inside a single device tree node. It made defining groups of pins for single purpose, but with different parameters very inconvenient. This patch implements Tegra-like support for grouping multiple pinctrl groups inside one device tree node, by completely changing the way pin groups and functions are parsed from device tree. The code creating pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while the initial creation of groups and functions has been completely rewritten with following assumptions: - each group consists of just one pin and does not depend on data from device tree, - each function is represented by a device tree child node of the pin controller, which in turn can contain multiple child nodes for pins that need to have different configuration values. Device Tree bindings are fully backwards compatible. New functionality can be used by defining a new pinctrl group consisting of several child nodes, as on following example: sd4_bus8: sd4-bus-width8 { part-1 { samsung,pins = "gpk0-3", "gpk0-4", "gpk0-5", "gpk0-6"; samsung,pin-function = <3>; samsung,pin-pud = <3>; samsung,pin-drv = <3>; }; part-2 { samsung,pins = "gpk1-3", "gpk1-4", "gpk1-5", "gpk1-6"; samsung,pin-function = <4>; samsung,pin-pud = <4>; samsung,pin-drv = <3>; }; }; Tested on Exynos4210-Trats board and a custom Exynos4212-based one.

2013-05-21pinctrl: Add pinctrl-s3c24xx driverHeiko Stuebner
The s3c24xx pins follow a similar pattern as the other Samsung SoCs and can therefore reuse the already introduced infrastructure. The s3c24xx SoCs have one design oddity in that the first 4 external interrupts do not reside in the eint pending register but in the main interrupt controller instead. We solve this by forwarding the external interrupt from the main controller into the irq domain of the pin bank. The masking/acking of these interrupts is handled in the same way. Furthermore the S3C2412/2413 SoCs contain another oddity in that they keep the same 4 eints in the main interrupt controller and eintpend register and requiring ack operations to happen in both. This is solved by using different compatible properties for the wakeup eint node which set a property accordingly.

2012-09-07pinctrl: add samsung pinctrl and gpiolib driverThomas Abraham
Add a new device tree enabled pinctrl and gpiolib driver for Samsung SoC's. This driver provides a common and extensible framework for all Samsung SoC's to interface with the pinctrl and gpiolib subsystems. This driver supports only device tree based instantiation and hence can be used only on those Samsung platforms that have device tree enabled. This driver is split into two parts: the pinctrl interface and the gpiolib interface. The pinctrl interface registers pinctrl devices with the pinctrl subsystem and gpiolib interface registers gpio chips with the gpiolib subsystem. The information about the pins, pin groups, pin functions and gpio chips, which are SoC specific, are parsed from device tree node.
