Merge tag 'samsung-drivers-7.2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/drivers
Samsung SoC drivers for v7.2
Improve Samsung Exynos (and Google GS101) ACPM (Alive Clock and Power
Manager) firmware driver:
1. Few code improvements.
2. Add support for protocol used to communicate with Thermal Management
Unit (TMU). This will allow to implement the thermal driver working
for newer Samsung Exynos and Google GS101 SoCs.
