In new Exynos SoCs (like Exynos850) where HSI2C is implemented as a
part of USIv2 block, there are two clocks provided to HSI2C controller:
  - PCLK: bus clock (APB), provides access to register interface
  - IPCLK: operating IP-core clock; SCL is derived from this one

Both clocks have to be asserted for HSI2C to be functional in that case.

Add code to obtain and enable/disable PCLK in addition to already
handled operating clock. Make it optional though, as older Exynos SoC
variants only have one HSI2C clock.

This one doesn't apply here? What tree is this based on?

Based on linux-next. Might got outdated, or maybe I had some debug
patches in my branch at the time. Anyway, I've sent v3 only for this
patch [1]. Can you please try to apply that one?

Thanks!
