Convert reset manager for Gen5, Arria 10 and Stratix 10 from struct to defines. Change to get reset manager base address from DT node instead of using #define. spl_early_init() initializes the DT setup. So, move spl_early_init() to beginning of function and before get base address from DT. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com> --- v6: - Call to socfpga_get_rstmgr_addr() function, instead of access to global variable directly. - Update socfpga_get_base_addr() to return error code, instead of return 0. v5: - Change macro values with 0x** format. v4: - Update commit message about get base address from DT node. v3: - Remove "No functional change" in commit description. v2: - Get base address from DT - Revert to use writel(), readl(), setbits_le32() and clrbits_le32(). - Add prefix to defines. --- arch/arm/mach-socfpga/include/mach/misc.h | 1 + .../mach-socfpga/include/mach/reset_manager.h | 2 + .../include/mach/reset_manager_arria10.h | 43 ++++------------ .../include/mach/reset_manager_gen5.h | 22 ++++----- .../include/mach/reset_manager_s10.h | 33 ++----------- arch/arm/mach-socfpga/misc.c | 41 ++++++++++++++++ arch/arm/mach-socfpga/misc_gen5.c | 7 ++- arch/arm/mach-socfpga/reset_manager_arria10.c | 49 ++++++++++--------- arch/arm/mach-socfpga/reset_manager_gen5.c | 28 +++++------ arch/arm/mach-socfpga/reset_manager_s10.c | 35 ++++++------- arch/arm/mach-socfpga/spl_a10.c | 7 ++- arch/arm/mach-socfpga/spl_gen5.c | 14 +++--- arch/arm/mach-socfpga/spl_s10.c | 12 +++-- drivers/sysreset/sysreset_socfpga.c | 6 +-- 14 files changed, 150 insertions(+), 150 deletions(-)
