Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c fixes from Wolfram Sang:
"I2C has one buildfix, one ABBA deadlock fix, and three simple 'add ID'
patches"
* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: exynos5: Fix possible ABBA deadlock by keeping I2C clock prepared
i2c: cpm: Fix build break due to incompatible pointer types
i2c: ismt: Add Intel DNV PCI ID
i2c: xlp9xx: add support for Broadcom Vulcan
i2c: rk3x: add support for rk3228

config I2C_XLP9XX
tristate "XLP9XX I2C support"
- depends on CPU_XLP || COMPILE_TEST
+ depends on CPU_XLP || ARCH_VULCAN || COMPILE_TEST
help
This driver enables support for the on-chip I2C interface of
- the Broadcom XLP9xx/XLP5xx MIPS processors.
+ the Broadcom XLP9xx/XLP5xx MIPS and Vulcan ARM64 processors.
This driver can also be built as a module. If so, the module will
be called i2c-xlp9xx.
