* thermal: exynos: Add the support for Exynos5433 TMUChanwoo Choi2015-05-041-0/+1
| | | | | | | | | | | | | | This patch adds the support for Exynos5433's TMU (Thermal Management Unit). Exynos5433 has a little different register bit fields as following description: - Support the eight trip points for rising/falling interrupt by using two registers - Read the calibration type (1-point or 2-point) and sensor id from TRIMINFO register - Use a little different register address Cc: Zhang Rui <rui.zhang@intel.com> Cc: Eduardo Valentin <edubezval@gmail.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
* thermal: exynos: Add TMU support for Exynos7 SoCAbhilash Kesavan2015-01-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* thermal: samsung: core: Exynos TMU rework to use device tree for configurationLukasz Majewski2015-01-241-60/+1
| | | | | | | | | | This patch brings support for providing configuration via device tree. Previously this data has been hardcoded in the exynos_tmu_data.c file. Such approach was not scalable and very often required copying the whole data. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
* thermal: exynos: Modify exynos thermal code to use device tree for cpu ↵Lukasz Majewski2015-01-241-5/+0
| | | | | | | | | | | | cooling configuration Up till now exynos_tmu_data.c was used for storing CPU cooling configuration data. Now the Exynos thermal core code uses device tree to get this data. For this purpose generic thermal code for configuring CPU cooling was used. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
* thermal: exynos: Provide thermal_exynos.h file to be included in device tree ↵Lukasz Majewski2015-01-241-9/+3
| | | | | | | | | | | | | | | | files This patch is a preparatory patch to be able to read Exynos thermal configuration from the device tree. It turned out that DTC is not able to interpret enums properly and hence it is necessary to #define those values explicitly. For this reason the ./include/dt-bindings/thermal/thermal_exynos.h file has been introduced.

* thermal: exynos: remove exynos_tmu_data.h includeBartlomiej Zolnierkiewicz2014-11-201-0/+8
| | | | | | | | | | | | | | | | | | | There is no longer need to share defines between exynos_tmu.c and exynos_tmu_data.c (as they are now only used by the former file) so move them accordingly. Then move externs for struct exynos_tmu_init_data instances to exynos_tmu.h and remove no longer needed exynos_tmu_data.h include. There should be no functional changes caused by this patch.

* thermal: exynos: fix IRQ clearing on TMU initializationBartlomiej Zolnierkiewicz2014-11-021-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Factor out code for clearing raised IRQs from exynos_tmu_work() to exynos_tmu_clear_irqs(). * Add a comment about documentation bugs to exynos_tmu_clear_irqs(). [ The documentation for Exynos3250, Exynos4412, Exynos5250 and Exynos5260 incorrectly states that INTCLEAR register has a different placing of bits responsible for FALL IRQs than INTSTAT register. Exynos5420 and Exynos5440 documentation is correct (Exynos4210 doesn't support FALL IRQs at all). ] * Use exynos_tmu_clear_irqs() in exynos_tmu_initialize() instead of open-coded code trying to clear IRQs according to predefined masks. After this change exynos_tmu_initialize() just clears IRQs that are raised like it is already done in exynos_tmu_work(). As a nice side-effect the code now uses the correct offset (16 instead of 12) for bits responsible for clearing FALL IRQs in INTCLEAR register on Exynos3250, Exynos4412 and Exynos5250. * Remove no longer needed intclr_rise_[mask,shift] and intclr_fall_[mask,shift] fields from struct exynos_tmu_registers. * Remove no longer needed defines. This patch has been tested on Exynos4412 and Exynos5420 SoCs.
