2022-02-07dt-bindings: i2c: samsung,s3c2410-i2c: convert to dtschemaKrzysztof Kozlowski1-58/+0
Convert the Samsung S3C24xx/S3C64xx/S5PV210/Exynos SoC I2C Controller bindings to DT schema format. The conversion includes also changes/fixes to the bindings, matching the real hardware and existing Linux driver: 1. Do not require interrupts on samsung,exynos5-sata-phy-i2c, because there is no such. 2. Do not allow gpios on samsung,exynos5-sata-phy-i2c, because they are hard-wired just like for HDMI phy. 3. Do not require samsung,i2c-sda-delay and use default of 0. 4. Require clock, which was always required but missing in bindings.

2018-04-30i2c: s3c2410: Remove support for Exynos5440Krzysztof Kozlowski1-3/+1
The Exynos5440 is not actively developed, there are no development boards available and probably there are no real products with it. Remove wide-tree support for Exynos5440.

2014-11-27ARM: dts: add sysreg phandle to i2c device nodes for exynosPankaj Dubey1-0/+1
This patch adds syscon based phandle to i2c device nodes of exynos5250 and exynos5420. These phandles will be used to save restore i2c sysreg configuration register during s2r from i2c driver.

2014-01-03i2c: s3c2410: Add polling mode supportVasanth Ananthan1-0/+2
This patch adds polling mode support for i2c-s3c2410 driver.The SATA PHY controller's CMU and TRSV block's are of I2C register map in exynos5250.These blocks can be configured using i2c. But i2c controller instance on which these block's sits lacks an interrupt line.Also the current i2c-s3c2410 driver is only interrupt driven, thus a polling mode support is required in the driver for supporting this controller. This patch adds this support to the driver.

2012-11-15bindings: i2c: use consistent naming for i2c binding descriptionsWolfram Sang1-0/+43
Filenames of devictree binding documentation seems to be arbitrary and for me it is unneeded hazzle to find the corresponding documentation for a specific driver. Naming the description the same as the driver is a lot easier and makes sense to me since the driver defines the binding it understands. Also, remove a reference in one source to the binding documentation, since path information easily gets stale.
