[PATCH 0/6] i2c: exynos5: Add support for modern Exynos SoCs

[Sam Protsenko]

Modern ARM64 Samsung Exynos SoCs (like Exynos Auto V9 and Exynos850) use
pretty much the same High-Speed I2C controller supported in i2c-exynos5
driver ("samsung,exynos7-hsi2c" variant), but with some differences:
  - timings are now calculated and configured a bit differently
  - two clocks are now provided to HSI2C controller (and must be
    asserted during I2C operation and register access)

This patch series implements these changes, making it possible to use
HSI2C driver on modern Exynos SoCs.

Another change in mentioned SoCs is that HSI2C controller is now a part
of USIv2 IP-core. But no USI modifications are needed in HSI2C driver,
as all USI related configuration is done in USI driver independently.
USI driver is added in [1] series (or its later revision, if available).
To make HSI2C functional, both patch series (this one and [1]) have to
be applied, but those can be applied independently.
