Move Stratix10 and Agilex reset manager common code to reset_manager_soc64.h. Changed macros to RSTMGR_SOC64_*.
Remove unused RSTMGR_XXX defines.
Signed-off-by: Ley Foon Tan ley.foon.tan@intel.com Reviewed-by: Simon Goldschmidt simon.k.r.goldschmidt@gmail.com
--- v5: - Remove reset_manager_s10.h and use reset_manager_soc64.h directly.
v4: - Change prefix from RSTMGR_S10* to RSTMGR_SOC64*.
v3: - Add new reset_manager_soc64.h - Convert to use defines instead of struct. --- .../mach-socfpga/include/mach/reset_manager.h | 2 +- .../include/mach/reset_manager_s10.h | 95 ------------------- .../include/mach/reset_manager_soc64.h | 38 ++++++++ arch/arm/mach-socfpga/reset_manager_s10.c | 20 ++-- 4 files changed, 49 insertions(+), 106 deletions(-) delete mode 100644 arch/arm/mach-socfpga/include/mach/reset_manager_s10.h create mode 100644 arch/arm/mach-socfpga/include/mach/reset_manager_soc64.h
