Hi Lukasz,
1. Introduction
Following patches aim to clean up the current implementation of the
thermal framework on Exynos devices.
The main goal was to use a generic code for reading thermal
configuration (of-thermal.c). Due to that redundant
exynos_thermal_common.[h|c] files were

Hi,
The goal of the patch 2 is to add runtime PM to the Exynos DSI driver.
This allows LCD power domain to be turned off.
However after adding this patch an interesing issue came in. The DSI
driver could not runtime resume during sustem resume because power
domain was not allowed to power on.
When resuming the system the power domain has to be powered on early so
any runtime PM aware devices could resume.
This fixes following scenario reproduced on Exynos DRM:
1. Power domain is off before suspending the system.
2. System is suspended to RAM.
3. Resuming starts. The Exynos DRM driver
Add runtime Power Management to the Exynos DSI driver so the LCD power
domain could be turned off.
This slightly reduces the energy consumption when screen is completely
turned off. On Trats2 board when the system was idle the energy
consumption dropped by 1% (from 92.2 mA to 91.1 mA).

I'm really not surprised.
When SoC have MCT_INT_SPI interrupt it is being allocated after hotplugging

I've picked up these patches and I'm planning to send a pull request
to Mike this week, including any other pending samsung clk patches.
Tomasz is going to be busy for few days.
