Subject: [PATCH v3 0/6] arm64: dts: exynos8895: define usi and mmc nodes

Hey folks,

This patch series adds the required syscons for controlling USI, as well
as defines all USIv1 nodes for Exynos8895 and adds support for utilizing
the external SD card storage in dreamlte as well as touchscreen. Due to
PMIC not being supported yet, we'll assume that the regulators are
pre-enabled by the previous bootloader for vqmmc, ts_vdd/avdd
(in our case uniLoader).

The patchset relies on [1]. I also expect the exynos mmc binding
maintainer to pick the specific-compat patch.

Best regards,
Ivaylo

Changes since v2:
  - add r-b from Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
  - drop hsi2c_pclk clock-name where it was left accidentally
  - utilize _I_PCLK instead of _I_SCLK_USI for all usi hsi2c nodes
  - move assigned-clocks properties to dtsi
  - set mmc's clock-frequency to 800mhz as per vendor's dt
  - add a pinctrl node describing cd-gpios
  - drop the fixed gpio regulator
  - add a new patch to the series for enabling s6sy761
