Start moving some spi_setup() functionality into the SPI core from the
various spi_master controller drivers:
- Make that function stop being an inline;
- Move two common idioms from drivers into that new function:
* Default bits_per_word to 8 if that field isn't set
* Issue a standardized dev_dbg() message
This is a net minor source code shrink, and supports enhancments found in
some follow-up patches.

Since ASIC3 has to work on both PXA and S3C and since their
struct clk implementations differ, we can't register out
clocks with the clkdev mechanism (yet?).
For now we have to keep clock handling internal to this
driver and enable/disable the clocks via the
mfd_cell->enable/disable functions.

The PCAP Asic as present on EZX phones is a multi function device with
voltage regulators, ADC, touch screen controller, RTC, USB transceiver,
leds controller, and audio codec.
It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.
This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons. After more than two years it's
time to remove them finally.
This patch cleans up one of the remaining users. When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: Fix section mismatch.
clocks_init() has been called from twl4030_probe() which is a non-init
function. Since probing can be done anytime so clocks_init will be
called anytime too. So we mark clock_init() as non-init.

It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures. ia64 (in common with several
other 64-bit architectures) currently uses unsigned long. Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.
Note that userspace will still see __u64 defined as unsigned long. This
is important as it affects C++ name mangling.
[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
u64 for start/end rather than unsigned long]

With KMS we have ran into an issue where we really want the KMS fb driver
to be the one running the console, so panics etc can be shown by switching
out of X etc.
However with vesafb/efifb built-in, we end up with those on fb0 and the
KMS fb driver on fb1, driving the same piece of hw, so this adds an fb
info flag to denote a firmware fbdev, and adds a new aperture base/size
range which can be compared when the hw drivers are installed to see if
there is a conflict with a firmware driver, and if there is the firmware
driver is unregistered and the hw driver takes over.
It uses new aperture_base/size members instead of comparing on the fix
smem_start/length, as smem_start/length might for example only cover the
first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB
into the aperture, thus they would never overlap.

With this change, the driver builds fine on Microblaze, which helps
allyesconfig compile tests.
I did not test sparc, but the change should have the same effect there.

The OpenFirmware part of this driver is uncompilable on SPARC due to it's
dependance on several PPC specific functions.
Restricting this to PPC to prevent these build errors:
CC drivers/video/mb862xx/mb862xxfb.o
drivers/video/mb862xx/mb862xxfb.c: In function 'of_platform_mb862xx_probe':
drivers/video/mb862xx/mb862xxfb.c:559: error: implicit declaration of function 'of_address_to_resource'
drivers/video/mb862xx/mb862xxfb.c:575: error: 'NO_IRQ' undeclared (first use in this function)
drivers/video/mb862xx/mb862xxfb.c:575: error: (Each undeclared identifier is reported only once
drivers/video/mb862xx/mb862xxfb.c:575: error: for each function it appears in.)
This was found using randconfig builds.

Add support for the ARGB1888 and ARGB4888 hardware to the Samsung SoC
Framebuffer driver (s3c-fb.c).
ARGB1888 and ARGB4888 is decided by var->transp.length and this variable
is set by s3c_fb_check_var().
In s3c_fb_check_var(), if var->vits_per_pixel is 25 or 28, then
var->transp.length would be 1 or 3.
Therefore alpha mode(ARGB1888 or ARGB4888) could be decided through that
variable.
For using alpha mode, you need to set the following: This code should be
added to your machine code as platform data.
static struct s3c_fb_pd_win xxx_fb_win0 = {
/* this is to ensure we use win0 */
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 24,
};
static struct s3c_fb_pd_win xxx_fb_win1 = {
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 28,
};
static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
.win[0] = &ncp_fb_win0,
.win[1] = &ncp_fb_win1,
.vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
.vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC,
.setup_gpio = xxx_fb_gpio_setup,
};
s3c_fb_set_platdata(&xxx_lcd_pdata);
The above code sets pixelformat for window0 layer to RGB888 and window1
layer to ARGB4888.
