Add registers, bit fields and compatible strings for Exynos7 TMU
(Thermal Management Unit). Following are a few of the differences
in the Exynos7 TMU from earlier SoCs:
- 8 trigger levels
- Different bit offsets and more registers for the rising
and falling thresholds.
- New power down detection bit in the TMU_CONTROL register
which does not update the CURRENT_TEMP0 when tmu power down
is detected.
- Change in bit offset for the NEXT_DATA field of EMUL_CON
register. EMUL_CON register address has also changed.
- INTSTAT and INTCLEAR registers present in earlier SoCs
have been combined into one INTPEND register. The register
address for INTCLEAR and INTPEND is also different.
- Since there are 8 rising/falling interrupts as against
at most 4 in earlier SoCs the INTEN bit offsets are different.
- Multiple probe support which is handled by a TMU_CONTROL1
register (No support for this in the current patch).
This patch adds special clock support required only for Exynos7. It
also updates the "code_to_temp" prototype as Exynos7 has 9 bit
code-temp mapping.
