This adds a core driver for the AB3100 mixed-signal circuit
found in the ST-Ericsson U300 series platforms. This driver
is a singleton proxy for all accesses to the AB3100
sub-drivers which will be merged on top of this one, RTC,
regulators, battery and system power control, vibrator,
LEDs, and an ALSA codec.

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: cleanup

Convert the last remaining users and remove the typedef.

clocks_init() has been called from twl4030_probe() which is a non-init

called anytime too. So we mark clock_init() as non-init.

Authentication error abort codes should be translated to appropriate
Linux error codes, rather than all being translated to EREMOTEIO - which
indicates that the server had internal problems.

Additionally, a server shouldn't be marked unavailable and the next
server tried if an authentication error occurs.  This will quickly make
all the servers unavailable to the client.  Instead the error should be
returned straight to the user.

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.

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);

AFAICT the code which checks that the requested pixclock value is within
bounds is incorrect.  It ensures that the lcdc core clock is at least
(bytes per pixel) times higher than the pixel clock rather than just
greater than or equal to.

There are tighter restrictions on the pixclock value as a function of bus
width for STN panels but even then it isn't a simple relationship as
currently checked for.  IMO either something like the below patch should
be applied or else more detailed checking logic should be implemented
which takes in to account the panel type as well.

The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis.  Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.

To make the configuration effective, the IRQ lines need to be set up
appropriately.  This patch also adds a way to do that from board support
code.

The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.
