imx8m mini LPDDR4 # 4.17.78
As follow codes,
when i change the pixclk :.clock there is nothing change about the MIPI_CLK.
where should i change if i want to change the MIPI_CLK.
static const struct drm_display_mode default_mode = {
.clock = 90000,
.hdisplay = 1920,
.hsync_start = 1920 + 2,
.hsync_end = 1920 + 2 + 2,
.htotal = 1920 + 2 + 2 + 2,
.vdisplay = 1280,
.vsync_start = 1280 + 4,
.vsync_end = 1280 + 4 + 4,
.vtotal = 1280 + 4 + 4 + 4,
.vrefresh =36,
.width_mm = 61,
.height_mm = 110,
.flags = DRM_MODE_FLAG_NHSYNC |
DRM_MODE_FLAG_NVSYNC,
Hi giao
for clock one can look at line 530
panel-raydium-rm67191.c\panel\drm\gpu\drivers - linux-imx - i.MX Linux kernel
and line 1283
sec-dsim.c\bridge\drm\gpu\drivers - linux-imx - i.MX Linux kernel
Best regards
igor

Now i try to change PHY_REF_CLK 27000000 to 2400000 the lane MIPI_CLK have changed ,but i want know why there is 27Mhz rather than 24Mhz ? M_XI in the datesheet 13.6.8.4 means 27Mhz??Should i change my hardware ?
Now the clkin1 and clkin2 is NC
Thanks for you answer,I have tried to change the code from the two places.But there is also no change about the MIPI_CLK (about 450Mhz)。Is there any other place should I to change?
