Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk
tree, the glitchy parent mux of ldb_di[x]_clk can cause a glitch to
enter the ldb_di_ipu_div divider. If the divider gets locked up, no
ldb_di[x]_clk is generated, and the LVDS display will hang when the

For better readability should this code be reviewed
in future, replace the hardcoded input numbers
with an enum.
This is just a cosmetic change and was verified
to not affect clk-imx6.o.

MMDC CH1 is not used on i.MX6Q, so the handshake needed to change the
parent of periph2_sel or the divider of mmdc_ch1_axi_podf will never
succeed.
Disable the handshake mechanism to allow changing the frequency of
mmdc_ch1_axi, allowing to use it as a possible source for the

Short version:
barebox always reparents the ldb_di[01] clocks to pll5_video_div.
Due to a hardware erratum, this can trigger a glitch that causes
LDB lock up.
Thus:
1) remove the automatic reparenting, like the kernel now does and
mark the affected clocks read only, so assigned-clock-parents
barebox has inherited the clk_set_parent(ldb_diN_sel, pll5_video_div)
from upstream kernel commit 32f3b8da22 ("ARM i.MX6q: set the LDB serial
clock parent to the video PLL"), where it was enabled for all i.MX6Q
revisions after 1.0. It was applied whenever CONFIG_DRIVER_VIDEO_IMX_IPUV3
was defined.
if written_length is read from a partial written bucket it may be to
big and xmalloc will panic barebox.
Check if the value is sane.
