| | | | | | | | The IPU has a fractional pixelclock divider. When used, this produces clock jitter which especially LVDS transceivers can't handle. Allow to disable it via platform_data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | No need to hardcode the channel parameters for the rgb offsets, we can calculate them from the fb_bitfields. ipu_ch_param_write_field() is the same as is the mainline IPUv3 driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* video: ipufb: do not use bitfieldsSascha Hauer2013-12-201-142/+129
| | | | | | | | bitfields are not portable and one should make assumptions of the layout of bitfields. Replace them with the ipu_ch_param_write_field() which is already used in the mainline IPUv3 driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* video: ipufb: make disp_data_fmt configurableSascha Hauer2013-12-181-26/+18
| | | | | | | | With the IPU the way the display is connected is completely independent of the framebuffer pixel format. So instead of specifying a pixel width in platform_data we have to specify how the display is connected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: MXS: introduce stmp device supportSascha Hauer2013-07-231-5/+6
| | | | | | | | | | | | MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.

| * i.MX21/27: don't enable lcd bus clocks too earlyDaniel Mierswa2013-01-171-7/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the MX27 based board phycard-i.MX27 the display won't properly come up. Before removing imx-regs.h and the code that sets the register in the i.MX video driver, the PCCR registers were set _after_ the screen start (LSSAR) was set. This restores that old behaviour and makes the display come up properly again. I did not have a chance to test this on any other i.MX27 or i.MX21 hardware though I assume that the "old" order is required there too.
