Merge branch 'i2c/for-5.0' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "I2C has only driver updates for you this time. Mostly new IDs/DT compatibles, also SPDX conversions, small cleanups. STM32F7 got FastMode+ and PM support, Axxia some reliabilty improvements" * 'i2c/for-5.0' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (26 commits) i2c: Add Actions Semiconductor Owl family S700 I2C support dt-bindings: i2c: Add S700 support for Actions Semi Soc's i2c: ismt: Add support for Intel Cedar Fork i2c: tegra: Switch to SPDX identifier i2c: tegra: Add missing kerneldoc for some fields i2c: tegra: Cleanup kerneldoc comments i2c: axxia: support sequence command mode dt-bindings: i2c: rcar: Add r8a774c0 support dt-bindings: i2c: sh_mobile: Add r8a774c0 support i2c: sh_mobile: Add support for r8a774c0 (RZ/G2E) i2c: i2c-cros-ec-tunnel: Switch to SPDX identifier. i2c: powermac: Use of_node_name_eq for node name comparisons i2c-axxia: check for error conditions first i2c-axxia: dedicated function to set client addr dt-bindings: i2c: Use correct vendor prefix for Atmel i2c: tegra: replace spin_lock_irqsave with spin_lock in ISR eeprom: at24: add support for 24c2048 dt-bindings: eeprom: at24: add "atmel,24c2048" compatible string i2c: i2c-stm32f7: add PM Runtime support i2c: sh_mobile: add support for r8a77990 (R-Car E3) ...
