      regmap: regmap: avoid spurious warning in regmap_read_debugfs · a3471469
      Russell King authored
      
      
      Gcc warns about the case where regmap_read_debugfs tries to walk an
      empty map->debugfs_off_cache list, which would results in uninitialized
      variable getting returned, if we hadn't checked the same condition
      just before that.
      
      After an originally suggested inferior patch from Arnd Bergmann,
      this is the solution that Russell King came up with, sidestepping
      the problem by merging the error case for an empty list with the
      normal path.
      
      Without this patch, building mxs_defconfig results in:
      
      drivers/base/regmap/regmap-debugfs.c: In function 'regmap_read_debugfs':
      drivers/base/regmap/regmap-debugfs.c:147:9: : warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]

      regmap: implement register striding · edc9ae42
      Stephen Warren authored
      
      
      regmap_config.reg_stride is introduced. All extant register addresses
      are a multiple of this value. Users of serial-oriented regmap busses will
      typically set this to 1. Users of the MMIO regmap bus will typically set
      this based on the value size of their registers, in bytes, so 4 for a
      32-bit register.
      
      Throughout the regmap code, actual register addresses are used. Wherever
      the register address is used to index some array of values, the address
      is divided by the stride to determine the index, or vice-versa. Error-
      checking is added to all entry-points for register address data to ensure
      that register addresses actually satisfy the specified stride. The MMIO
      bus ensures that the specified stride is large enough for the register
      size.

      regmap: allow regmap instances to be named · 4b5c0186
      Stephen Warren authored
      
      
      Some devices have multiple separate register regions. Logically, one
      regmap would be created per region. One issue that prevents this is that
      each instance will attempt to create the same debugfs files. Avoid this
      by allowing regmaps to be named, and use the name to construct the
      debugfs directory name.

      simple_open: automatically convert to simple_open() · 234e3405
      Stephen Boyd authored
      
      
      Many users of debugfs copy the implementation of default_open() when
      they want to support a custom read/write function op.  This leads to a
      proliferation of the default_open() implementation across the entire
      tree.
      
      Now that the common implementation has been consolidated into libfs we
      can replace all the users of this function with simple_open().
      
      This replacement was done with the following semantic patch:
      
      <smpl>
      @ open @
      identifier open_f != simple_open;
      identifier i, f;
      @@
      -int open_f(struct inode *i, struct file *f)
      -{
      (
      -if (i->i_private)
      -f->private_data = i->i_private;
      |
      -f->private_data = i->i_private;
      )
      -return 0;
      -}
      
      @ has_open depends on open @
      identifier fops;
      identifier open.open_f;
      @@
      struct file_operations fops = {
      ...
      -.open = open_f,
      +.open = simple_open,
      ...
      };
      </smpl>

      device.h: cleanup users outside of linux/include (C files) · 51990e82
      Paul Gortmaker authored
      
      
      For files that are actively using linux/device.h, make sure
      that they call it out.  This will allow us to clean up some
      of the implicit uses of linux/device.h within include/*
      without introducing build regressions.
      
      Yes, this was created by "cheating" -- i.e. the headers were
      cleaned up, and then the fallout was found and fixed, and then
      the two commits were reordered.  This ensures we don't introduce
      build regressions into the git history.
