Matthieu Simon c075b6f2d3 staging: sm750fb: Replace POKE32 and PEEK32 by inline functions
POKE32 and PEEK32 have been replaced by inlined functions poke32 and
peek32.
Having inline functions instead of macros help to get the correct
type-checking and avoid the possible precedence issues reported by
checkpatch.

Dan Carpenter d28fb1ffba staging: sm750fb: fix a type issue in sm750_set_chip_type()
"revId" needs to be unsigned because we use it to test:

	if (revId == SM750LE_REVISION_ID) {

and SM750LE_REVISION_ID is ((unsigned char )0xfe).

Arnd Bergmann 52d0744d75 staging: sm750fb: prefix global identifiers
Renaming some symbols inside this driver caused a conflict with
an existing function, which in turn results in a link error:

drivers/staging/sm750fb/sm750fb.o: In function `enable_dma':
ddk750_hwi2c.c:(.text.enable_dma+0x0): multiple definition of `enable_dma'

This adds a sm750_ prefix to each global symbol in the sm750fb
driver that does not already have one. I manually looked for the
symbols and then converted the driver using

for i in calc_pll_value format_pll_reg set_power_mode set_current_gate    \
	enable_2d_engine enable_dma enable_gpio enable_i2c hw_set2dformat \
	hw_de_init hw_fillrect hw_copyarea hw_imageblit hw_cursor_enable  \
	hw_cursor_disable hw_cursor_setSize hw_cursor_setPos		  \
	hw_cursor_setColor hw_cursor_setData hw_cursor_setData2 ;
do
		sed -i "s:\<$i\>:sm750_$i:" drivers/staging/sm750fb/*.[ch]
done

Elise Lennion efe9bc08bf staging: sm750fb: Merge ddk750_help.* into ddk750_chip.*.
The file ddk750_help.c contained only one function declaration,
so it was merged into ddk750_chip.c to simplify the driver.

Also, ddk750_help.h was merged into ddk750_chip.h to keep consistency.

With these changes a few global variables are removed and the function
ddk750_set_mmio is rewritten, so its purpose in the code is clearer.

Mihaela Muraru 9872fa751e Staging: sm750fb: fix do not add new typedefs warning
This patch fixes the checkpatch.pl warning: "WARNING: do not add new
typedefs". Hiding a variables of type 'struct' is not always a good
idea,because when we passing them as parameters we tempt to forget that
in this proces we work with  stack memory and allocatting struct on
stack is something that we should manage carefuly.

It is also delete the '_t' from the name of the structs and treat a line
over 80 character issue in ddk750_mode.c, that appear after my modification.

Lorenzo Stoakes f8b0dced35 staging: sm750fb: Cleanup the type of mmio750
This patch assigns the more appropriate void* type to the mmio750 variable
eliminating an unnecessary volatile qualifier in the process. Additionally it
updates parameter types as necessary where those parameters interact with
mmio750, removes unnecessary casts and updates the type of the
lynx_share->pvReg field which is passed to the ddk750_set_mmio method.

As a consequence, this patch fixes the following sparse warning:-

drivers/staging/sm750fb/ddk750_help.c:12:17: warning: incorrect type in assignment (different address spaces)
