2022-08-19dt-bindings: pinctrl: samsung: deprecate header with register constantsKrzysztof Kozlowski
For convenience (less code duplication, some meaning added to raw number), the pin controller pin configuration register values were defined in the bindings header. These are not some IDs or other abstraction layer but raw numbers used in the registers These constants do not fit the purpose of bindings. They do not provide any abstraction, any hardware and driver independent ID. With minor exceptions, the Linux drivers actually do not use the bindings header at all. All of the constants were moved already to headers local to DTS (residing in DTS directory) and to Samsung pinctrl driver (where applicable), so remove any references to the bindings header and add a warning tha tit is deprecated.

2021-12-20dt-bindings: pinctrl: samsung: Add pin drive definitions for Exynos850Sam Protsenko
All Exynos850 GPIO blocks can use EXYNOS5420_PIN_DRV* definitions, except GPIO_HSI block. Add pin drive strength definitions for GPIO_HSI block correspondingly.

2017-07-18pinctrl: samsung: dt-bindings: Use better name for external interrupt functionKrzysztof Kozlowski
On Exynos, 0xf is always used as value of external interrupt in pin mux function thus a more descriptive macro name can be used. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
2017-02-02pinctrl: dt-bindings: samsung: Add Exynos7 specific pinctrl macro definitionsPankaj Dubey
Exynos7 SoC pinctrl configurations are similar to existing Exynos4/5 except for FSYS1 pinctrl drive strengths. So adding Exynos7 specific FSYS1 blocks pinctrl driver strength related macros which will be used in Exynos7 DTSi files.

2017-01-06pinctrl: dt-bindings: samsung: add drive strength macros for Exynos5433Andi Shyti
Commit 5db7e3bb87df ("pinctrl: dt-bindings: samsung: Add header with values used for configuration") has added a header file for defining the pinctrl values in order to avoid hardcoded settings in the Exynos DTS related files. Extend samsung.h to the Exynos5433 for drive strength values which are strictly related to the particular SoC and may defer from others.

2016-09-16pinctrl: dt-bindings: samsung: Add header with values used for configurationKrzysztof Kozlowski
Hard-coded pinctrl configuration values are scattered through DTS files. The numbers are difficult to decode by human, especially without the datasheet. Additionally the drive strength differs between S3C64xx, S5PV210 and Exynos SoC families increasing the confusion. The header will help making this more readable and maintainable.
