I am trying to add LCD panel with LVDS interface for exynos 4412 topeet
itop. That board using a bridge chip to convert the parallel RGB signal
to LVDS signal. I could make a fb0 node appear in system now. But I can't
make it work yet. redirecting the urandom to fb0 won't make anything
change in panel.
The timing for this panel is calcuated from Hyundai T7, but it looks
different to the vendor's kernel. But those timings settings is disabled, so
I decided not to use it.
I attach them as references:
/* From Hyundai T7 */
static struct s3cfb_lcd hs101h = {
.width = 1280,
.height = 800,
.bpp = 24,
.freq = 60,
.timing = {
.h_fp = 49,
.h_bp = 17,
.h_sw = 33,
.v_fp = 4,
.v_fpe = 1,
.v_bp = 15,
.v_bpe = 1,
.v_sw = 6,
},
.polarity = {
.rise_vclk = 0,
.inv_hsync = 1,
.inv_vsync = 1,
.inv_vden = 0,
},
};
/* From vendor */
static struct s3cfb_lcd dummy_mipi_lcd = {
.width = 800,
.height = 1280,
.bpp = 24,
.freq = 60,
.timing = {
.h_fp = 16,
.h_bp = 140,
.h_sw = 14,
.v_fp = 8,
//.v_fpe = 2,
.v_bp = 4,
//.v_bpe = 1,
.v_sw = 4,
.cmd_allow_len = 4,
},
.polarity = {
.rise_vclk = 0,
.inv_hsync = 0,
.inv_vsync = 0,
.inv_vden = 0,
},
}

It is actually a lvds panel connected through a rga-lvds bridge.
The touchscreen is communicated with i2c bus but the driver is not
support now.

Isn't this one of S5M8767 PMIC regulators? If so, then it should be
defined there... On the other hand, the PMIC supports GPIO enable
control only for buck9...

Please put these nodes in alphabetical order. I asked about it for
initial DTS and it applies still.

Ah wait, it's a label, so underscore seems ok. My mistake.
