| | | | | | | | | | | | | | | | 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>

So, when erase blocks are written, the image sequence in the ec header is lost (set to zero). UBI scan_all() takes this case into account (commits 32bc4820287a1a03982979515949e8ea56eac641 and 2eadaad67b2b6bd132eda105128d2d466298b8e3) But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_peb_for_wl() removes the PEB from the free list. If the WL subsystem detects that no wear leveling is needed it cancels the operation and drops the gained PEB. In this case we have to put the PEB back into the free list.
