Hey folks,

This series adds HSI2C support for Exynos8895 to i2c-exynos5. HSI2C
buses here are mostly available implemented in USIv1 blocks, with 5
available externally - hsi2c_0 to 4. hsi2c_0 is available for PMIC
(although I've never seen it used) and it uses BUSC clocks, which are
still not implemented in the current clock driver, so I've decided to
leave it out for now.

In the next few patchsets support for USIv1 will be added to the
exynos-usi driver and with that the rest of the I2C buses will be made
available in the device tree.

Kind regards,
Ivo

Changes in v3:
 - Added a r-b tag from Krzysztof Kozlowski.
 - Changed the temp calculation for better clarity while also fixing
   an oversight (I2C_TYPE_EXYNOS8895 shouldn't -= t_ftl_cycle).
 - Changed the driver patch commit message as suggested.

Changes in v2:
 - Dropped nested-if in the binding, keeping in mind we'll always
   provide only a single clock.
