Subject: [PATCH 0/5] Bring up internal eMMC on Samsung Galaxy A8 (2018)

This set adds support to the internal eMMC storage found on the Samsung
Galaxy A8 (2018) (jackpotlte). It seems to work reliably for reads and
writes. postmarketOS is able to boot off of it.

The original kernel from samsung sets pinctrl options at runtime
changing pin-drv levels automatically. Without this code, mmc seems to
work the best with the lv3 setting on jackpotlte.

David Virag (5):
  dt-bindings: clock: Add bindings for Exynos7885 CMU_FSYS
  dt-bindings: clock: Add indices for Exynos7885 TREX clocks
  clk: samsung: exynos7885: Implement CMU_FSYS domain
  clk: samsung: exynos7885: Add TREX clocks
  arm64: dts: exynos: Add internal eMMC support to jackpotlte
