* thermal: samsung: Add TMU support for Exynos5420 SoCsNaveen Krishna Chatradhi2014-05-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | Exynos5420 has 5 TMU channels, the TRIMINFO register is misplaced for TMU channels 2, 3 and 4 TRIMINFO at 0x1006c000 contains data for TMU channel 3 TRIMINFO at 0x100a0000 contains data for TMU channel 4 TRIMINFO at 0x10068000 contains data for TMU channel 2 This patch 1 Adds the neccessary register changes and arch information to support Exynos5420 SoCs. 2. Handles the gate clock for misplaced TRIMINFO register 3.

* thermal: samsung: change base_common to more meaningful base_secondNaveen Krishna Chatradhi2014-05-061-2/+2
| | | | | | | | | | | | | | | | | | On Exynos5440 and Exynos5420 there are registers common across the TMU channels. To support that, we introduced a ADDRESS_MULTIPLE flag in the driver and the 2nd set of register base and size are provided in the "reg" property of the node. As per Amit's suggestion, this patch changes the base_common to base_second and SHARED_MEMORY to ADDRESS_MULTIPLE.

* thermal: samsung: replace inten_ bit fields with intclr_Naveen Krishna Chatradhi2014-05-061-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the inten_rise_shift/mask and inten_fall_shift/mask with intclr_rise_shift/mask and intclr_fall_shift/mask respectively. Currently, inten_rise_shift/mask and inten_fall_shift/mask bits are only used to configure intclr related registers. Description of H/W: The offset for the bits in the CLEAR register are not consistent across TMU modules in Exynso5250, 5420 and 5440. On Exynos5250, the FALL interrupt related en, status and clear bits are available at an offset of 16 in INTEN, INTSTAT registers and at an offset of 12 in INTCLEAR register. On Exynos5420, the FALL interrupt related en, status and clear bits are available at an offset of 16 in INTEN, INTSTAT and INTCLEAR registers. On Exynos5440, the FALL_IRQEN bits are at an offset of 4 and the RISE_IRQEN bits are at an offset of 0 Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Acked-by: Amit Daniel Kachhap <amit.daniel@samsung.com> Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Reviewed-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
* thermal: exynos: Provide initial setting for TMU's test MUX address at ↵Lukasz Majewski2013-10-151-0/+4
| | | | | | | | | | | | | | | | | Exynos4412 The commit d0a0ce3e77c795258d47f9163e92d5031d0c5221 ("thermal: exynos: Add missing definations and code cleanup") has removed setting of test MUX address value at TMU configuration setting. This field is not present on Exynos4210 and Exynos5 SoCs. However on Exynos4412 SoC it is required to set this field after reset because without it TMU shows maximal available temperature, which causes immediate platform shutdown.

* thermal: exynos: Provide separate TMU data for Exynos4412Lukasz Majewski2013-10-151-1/+2
| | | | | | | | | | | | | | | | | | Up till now Exynos5250 and Exynos4412 had the same definitions for TMU data. Following commit changes that, by introducing separate exynos4412_default_tmu_data structure. Since Exynos4412 was chronologically first, the corresponding name for TMU registers and default data was renamed. Additionally, new SOC_ARCH_EXYNOS4412 type has been defined. Moreover, the SOC_ARCH_EXYNOS name has been changed to SOC_ARCH_EXYNOS5250.

* thermal: exynos: Add hardware mode thermal calibration supportAmit Daniel Kachhap2013-08-131-0/+8
| | | | | | | | | | | This patch adds support for h/w mode calibration in the TMU controller. Soc's like 5440 support this features. The h/w bits needed for calibration setting are same as that of enum calibration_type.

* thermal: exynos: Add driver support for exynos5440 TMU sensorAmit Daniel Kachhap2013-08-131-0/+6
| | | | | | | | | | | | | | | This patch modifies TMU controller to add changes needed to work with exynos5440 platform. This sensor registers 3 instance of the tmu controller with the thermal zone and hence reports 3 temperature output. This controller supports upto five trip points. For critical threshold the driver uses the core driver thermal framework for shutdown.

* thermal: exynos: Add support to handle many instances of TMUAmit Daniel Kachhap2013-08-131-0/+13
| | | | | | | | | | | | | | | | | This patch adds support to handle multiple instances of the TMU controllers. This is done by removing the static structure to register with the core thermal and creating it dynamically for each instance of the TMU controller. The interrupt is made shared type to handle shared interrupts. Now since the ISR needs the core thermal framework to be registered so request_irq is moved after the core registration is done. Also the identifier of the TMU controller is extracted from device tree alias. This will be used for TMU specific initialisation.

| | | | | | | | | | | | This patch migrates the TMU register definition/bitfields to data file. This is needed to support SoC's which use the same TMU controller but register validity, offsets or bitfield may slightly vary across SOC's.

Also the driver is modified to use the data passed by these new platform memebers instead of the constant macros. All these changes helps in separating the SOC specific data part from the TMU driver.

* thermal: exynos: Move exynos_thermal.h from include/* to driver/* folderAmit Daniel Kachhap2013-08-131-0/+107
This patch renames and moves include/linux/platform_data/exynos_thermal.h to drivers/thermal/samsung/exynos_tmu.h. This file movement is needed as exynos SOC's are not supporting non-DT based platforms and this file now just contains exynos tmu driver related definations. Also struct freq_clip_table is now moved to exynos_thermal_common.c as it fixes the compilation issue occuring because now this new tmu header file is included in tmu driver c file and not in the common thermal header file.
