If I understand this code correctly, you can now always use EXYNOS5420_TMU_DATA for 5420-tmu compatible string and EXYNOS5420_TMU_DATA_SHARED for 5420-tmu-ext-triminfo.

Correct, To avoid changes to exynos_get_driver_data() function the exynos_get_driver_data struct is defined as above. As function exynos_get_driver_data(struct platform_device *pdev, int id) uses the id and matches the approriate structure pointer. > > Best regards, > Tomasz Thanks for your comments, will respin. >
