Most of the changes in this version is as per suggestion from Jonghwa Lee. I have retained one to one mapping of platform data with TMU instances as the TMU's are different devices. In exynos5440 soc there is some register sharing across multiple TMU's but in exynos5420 there is no register between multiple TMU's, so the current implementation is useful to support both of the above. This patch uses localized ARCH_HAS_TMU Kconfig option and is a temporary solution until a more generic macro ARCH_HAS_BANDGAP is introduced as per discussion in the link https://patchwork.kernel.org/patch/2659001/. Changes in V5: * trip type is passed as platform data. * HW trip is allowed only for maximum level. * Platform data structure is now abstracted inside 1 more structure to support strong multiple sensor TMU data. Changes in V4: Almost all the changes in this version is as per suggestion from Eduardo.The major ones are listed below, * Added kconfig symbol ARCH_HAS_TMU which needs to be enabled by platform. With this change existing symbol EXYNOS_TMU_DATA is not needed. * Movement of freq_clip_table from exynos_tmu.h to exynos_thermal_common.h is explained in the commit logs. * Wrote all register description documentation. * Split 5440 TMU support patch into controller change, configuration data and feature addition patches. * Remove all *LINUX_* in the header files. * Still regulator enable is kept optional but a TODO: comment is added to fix it later. Changes in V3: * Added proper dependency of different exynos thermal Kconfig symbols. Basically 3 Kconfig can be enabled now and corresponds to tmu driver. exynos common part and exynos configuration data. This issue was raised by Rui Zhang. Changes in V2: * Separated SOC data from TMU driver. This is as per suggestion from Eduardo. * Merged the new file created for exynos5440 TMU controller with the existing TMU controller code. * Removed the DT parsing code as now the SOC specific data are cleanly put inside the data specific file. * Even the register definations/bitfields are treated as data as there is some variation across SOC's. This patchset adds TMU(Thermal management Unit) driver support for exynos5440 platform. There are 3 instances of the TMU controllers so necessary cleanup/re-structure is done to handle multiple thermal zone. Patch (exynos4: Add documentation for Exynos SoC thermal bindings) from Lukasz Majewski is already posted to mainline. Adding it here for completeness. (http://www.mail-archive.com/linux-samsung-soc@xxxxxxxxxxxxxxx/msg17817.html) Patch (thermal: exynos: Support thermal tripping ) from Jonghwan Choi is added here with some changes. (https://patchwork.kernel.org/patch/1668371/) Patch (thermal: exynos: Support for TMU regulator defined at device tree) is a repost of my earlier patch(https://patchwork-mail1.kernel.org/patch/2510771/) and adds regulator support. Patch (ARM: dts: Add device tree node for exynos5440 TMU controller) and patch (arm: exynos: enable ARCH_HAS_TMU) can be merged through exynos platform maintainer as this can cause merge conflict. All these patches are based on thermal maintainers git tree, git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux.git next.
