Hi, Nice work. I had a little trouble following this one. Perhaps you are doing more than one thing per patch, feel free to ignore me if I am wrong but it seems you are moving the macro definition of CC_REG to a different header, adding the new inline functions and doing some other change that I can't grok (commented on below). Perhaps this patch could be broken up. > --- > drivers/staging/ccree/cc_hal.h | 33 ------------------ > drivers/staging/ccree/cc_regs.h | 35 -------------------- > drivers/staging/ccree/dx_reg_base_host.h | 25 -------------- > drivers/staging/ccree/ssi_driver.c | 47 ++++++++++++-------------- > drivers/staging/ccree/ssi_driver.h | 20 +++++++++-- > drivers/staging/ccree/ssi_fips.c | 12 +++---- > drivers/staging/ccree/ssi_pm.c | 4 +-- > drivers/staging/ccree/ssi_request_mgr.c | 57 > ++++++++++++++++---------------- > drivers/staging/ccree/ssi_sysfs.c | 11 +++--- > 9 files changed, 78 insertions(+), 166 deletions(-) > delete mode 100644 drivers/staging/ccree/cc_hal.h > delete mode 100644 drivers/staging/ccree/cc_regs.h > delete mode 100644 drivers/staging/ccree/dx_reg_base_host.h > > diff --git a/drivers/staging/ccree/cc_hal.h b/drivers/staging/ccree/cc_hal.h > deleted file mode 100644 > index eecc866..0000000 > --- a/drivers/staging/ccree/cc_hal.h > +++ /dev/null > @@ -1,33 +0,0 @@ > -/* > - * Copyright (C) 2012-2017 ARM Limited or its affiliates. > - * > - * This program is free software; you can redistribute it and/or modify > - * it under the terms of the GNU General Public License version 2 as > - * published by the Free Software Foundation. > - * > - * This program is distributed in the hope that it will be useful, > - * but WITHOUT ANY WARRANTY; without even the implied warranty of > - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
