Hi,
Running clang-analyzer[1] on the VOP2 driver in barebox[2], which was ported
from Linux reports that following variables:
dclk_out_div, if_pixclk_div, if_dclk_div
defined in rk3588_set_intf_mux() and passed to rk3588_calc_cru_cfg()
are given as uninitialized arguments to ilog2() and in som

When the Skov device trees were added a year ago, there were no
upstream bindings yet for many parts of the display pipeline.
This has changed now, so this series fleshes the display pipeline parts
out and adds some more fixes/enhancements that have accrued in the
meantime.

The TIAN-G07017-01 is a 7" TFT-LCD module by TOPLAND ELECTRONICS (H.K).
The panel features 1024x600 24-bit RGB pixels driven over LVDS as well
as a PWM backlight and I2C-connected ft5506-compatible capacitive touch.
This series adds DT binding and Linux driver support for this panel.

device_match_of_node() exists so a pointer to the function can be passed
to class/driver_find_device. I see no reason to call it directly.

This way hardware that has the LCD signal lines swapped can express
so in the device tree and existing panel support can be reused
unmodified.

This newly implemented binding allows expressing swapped signal
lanes in the device tree so existing panel support can be reused.

MEDIA_BUS_FMT_GBR888_1X24
The latter two patches add a new interface-pix-fmt property
(named so because fsl,imx-parallel-display has one),
which allows a device tree to override the bus format to account
for swapped signal lanes.
Thoughts?

The LCDIF controller v4, like the one included in the i.MX6UL,
can be configured to accept other RGB pixel formats. Extend
the driver to configure the controller to do so.
