sparc: Explicitly include correct DT includes

2023-08-28T18:30:57Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

floppy: use symbolic register names in the sparc64 port

2020-05-12T16:34:53Z

Now by splitting the base address from the register index we can use the symbolic register names instead of the hard-coded numeric values.

floppy: split the base port from the register in I/O accesses

2020-05-12T16:34:52Z

Currently we have architecture-specific fd_inb() and fd_outb() functions or macros, taking just a port which is in fact made of a base address and a register. The base address is FDC-specific and derived from the local or global "fdc" variable through the FD_IOPORT macro used in the base address calculation. This change splits this by explicitly passing the FDC's base address and the register separately to fd_outb() and fd_inb(). It affects the following archs: - x86, alpha, mips, powerpc, parisc, arm, m68k: simple remap of port -> base+reg - sparc32: use of reg only, since the base address was already masked out and the FDC controller is known from a static struct. - sparc64: like x86 for PCI, like sparc32 for 82077 Some archs use inline functions and others macros. This was not unified in order to minimize the number of changes to review. For the same reason checkpatch still spews a few warnings about things that were already there before. The parisc still uses hard-coded register values and could be cleaned up by taking the register definitions. The sparc per-controller inb/outb functions could further be refined to explicitly take an FDC register instead of a port in argument but it was not needed yet and may be cleaned later.

sparc: Use of_node_name_eq for node name comparisons

Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. Cc: "David S. Miller" Cc: sparclinux@vger.kernel.org Signed-off-by: Rob Herring Signed-off-by: David S. Miller
