Recently, I applied this patchset with exynos4412 and found it uses same register map with exynos5250. So, I think it should rename the any type of name containing exynos4 and exynos5 (e.g. SOC_ARCH_EXYNOS4) In my local, i renamed SOC_ARCH_EXYNOS4 to SOC_ARCH_EXYNOS4210 and SOC_ARCH_EXYNOS5 to SOC_ARCH_EXYNOS and other related name also. I recommend you to change all of name >> If it's same, it's better to use CONFIG_SOC_EXYNOS4? >>> +static struct exynos_tmu_platform_data const exynos4_default_tmu_data = { >>> + .threshold = 80, >>> + .trigger_levels[0] = 5, >>> + .trigger_levels[1] = 20, >>> + .trigger_levels[2] = 30, >>> + .trigger_level0_en = 1, >>> + .trigger_level1_en = 1, >>> + .trigger_level2_en = 1, >>> + .trigger_level3_en = 0, >>> + .gain = 15, >>> + .reference_voltage = 7, >>> + .cal_type = TYPE_ONE_POINT_TRIMMING, >>> + .freq_tab[0] = { >>> + .freq_clip_max = 800 * 1000, >>> + .temp_level = 85, >>> + }, >>> + .freq_tab[1] = { >>> + .freq_clip_max = 200 * 1000, >>> + .temp_level = 100, >>> + }, >>> + .freq_tab_count = 2, >>> + .type = SOC_ARCH_EXYNOS4, >>> +}; >>> +#define EXYNOS4_TMU_DRV_DATA (&exynos4_default_tmu_data) >>> +#else >>> +#define EXYNOS4_TMU_DRV_DATA (NULL) >>> +#endif >>> + >>> +#if defined(CONFIG_SOC_EXYNOS5250) >> similar. >>> +static struct exynos_tmu_platform_data const exynos5_default_tmu_data = { >>> + .trigger_levels[0] = 85, >>> + .trigger_levels[1] = 103, >>> + .trigger_levels[2] = 110, >>> + .trigger_level0_en = 1, >>> + .trigger_level1_en = 1, >>> + .trigger_level2_en = 1, >>> + .trigger_level3_en = 0, >>> + .gain = 8, >>> + .reference_voltage = 16, >>> + .noise_cancel_mode = 4, >>> + .cal_type = TYPE_ONE_POINT_TRIMMING, >>> + .efuse_value = 55, >>> + .freq_tab[0] = { >>> + .freq_clip_max = 800 * 1000, >>> + .temp_level = 85, >>> + }, >>> + .freq_tab[1] = { >>> + .freq_clip_max = 200 * 1000, >>> + .temp_level = 103, >>> + }, >>> + .freq_tab_count = 2, >>> + .type = SOC_ARCH_EXYNOS5, >>> +}; >>> +#define EXYNOS5_TMU_DRV_DATA (&exynos5_default_tmu_data) >>> +#else >>> +#define EXYNOS5_TMU_DRV_DATA (NULL) >>> +#endif >>> + >>> +#ifdef CONFIG_OF >>> +static const struct of_device_id exynos_tmu_match[] = { >>> + { >>> + .compatible = "samsung,exynos4-tmu", >>> + .data = (void *)EXYNOS4_TMU_DRV_DATA, >>> + }, >>> + { >>> + .compatible = "samsung,exynos5-tmu", >>> + .data = (void *)EXYNOS5_TMU_DRV_DATA, >>> + }, >>> + {}, >>> +}; >>> +MODULE_DEVICE_TABLE(of, exynos_tmu_match); >>> +#else >>> +#define exynos_tmu_match NULL >>> +#endif >>> + >>> +static struct platform_device_id exynos_tmu_driver_ids[] = { >>> + { >>> + .name = "exynos4-tmu", >>> + .driver_data = (kernel_ulong_t)EXYNOS4_TMU_DRV_DATA, >>> + }, >>> + { >>> + .name = "exynos5-tmu", >>> + .driver_data = (kernel_ulong_t)EXYNOS5_TMU_DRV_DATA, >>> + }, >>> + { }, >>> +}; >>> +MODULE_DEVICE_TABLE(platform, exynos4_tmu_driver_ids); >>> + >>> +static inline struct exynos_tmu_platform_data *exynos_get_driver_data( >>> + struct platform_device *pdev) >>> +{ >>> +#ifdef CONFIG_OF >>> + if (pdev->dev.of_node) { >>> + const struct of_device_id *match; >>> + match = of_match_node(exynos_tmu_match, pdev->dev.of_node); >>> + if (!match) >>> + return NULL; >>> + return (struct exynos_tmu_platform_data *) match->data; >>> + } >>> +#endif >>> + return (struct exynos_tmu_platform_data *) >>> + platform_get_device_id(pdev)->driver_data; >>> } >>> -; >>> static int __devinit exynos_tmu_probe(struct platform_device *pdev) >>> { >>> struct exynos_tmu_data *data; >>> struct exynos_tmu_platform_data *pdata = pdev->dev.platform_data; >>> int ret, i; >>> >>> + if (!pdata) >>> + pdata = exynos_get_driver_data(pdev); >>> + >>> if (!pdata) { >>> dev_err(&pdev->dev, "No platform init data supplied.\n"); >>> return -ENODEV; >>> @@ -838,9 +945,11 @@ static struct platform_driver exynos_tmu_driver = { >>> .name = "exynos-tmu", >>> .owner = THIS_MODULE, >>> .pm = EXYNOS_TMU_PM, >>> + .of_match_table = exynos_tmu_match, >>> }, >>> .probe = exynos_tmu_probe, >>> .remove = __devexit_p(exynos_tmu_remove), >>> + .id_table = exynos_tmu_driver_ids, >>> }; >>> >>> module_platform_driver(exynos_tmu_driver); >>> -- >>> 1.7.1 >>> >>> -- >>> To unsubscribe from this list: send the line "unsubscribe linux-kernel" in >>> the body of a message to majordomo@vger.kernel.org >>> More majordomo info at http://vger.kernel.org/majordomo-info.html >>> Please read the FAQ at http://www.tux.org/lkml/ >> -- >> To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in >> the body of a message to majordomo@vger.kernel.org >> More majordomo info at http://vger.kernel.org/majordomo-info.html > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
