34308fd4a acornfb: remove fb_mmap function ... Browse Code »

The driver's fb_mmap function is essentially the same as a generic fb_mmap
function. Delete driver's function and use the generic one.

A difference is that generic function marks frame buffer memory as VM_IO |
VM_RESERVED. The driver's function marks it as VM_IO only.

39000d654 Samsung SoC Framebuffer driver: add Alpha Channel support ... Browse Code »

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.

97b9a5a28 atmel-lcdc: fix pixclock upper bound detection ... Browse Code »

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.

8f3128e71 lis3: add click function ... Browse Code »

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.

a002ee896 lis3: remove automatic shutdown of the device ... Browse Code »

After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision). So let's keep the
device always on. It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.

Moreover, since commit ef2cfc790bf5f0ff189b01eabc0f4feb5e8524df had been
too zealous, the device was actually never turned off anyway. This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.

Also do more clean up with the usage of the lis3_dev global variable.

O: node to be deleted
N: the successor of O
P: parent of N
C: child of N
L: some other node
