In upstream-v5.8, dsi_enable will operate panel_enable, but this
modification has been moved in v5.9. In order to ensure the timing of
dsi_power_on/off and the timing of pulling up/down the MIPI signal,
the modification of v5.9 is synchronized in this series of patches.
Hello,
I'm trying to debug an issue on mt8183 kukui krane sku176 device.
The problem is that boe-tv101wum-nl6 panel isn't working.
At boot time I can see these logs:
panel-boe-tv101wum-nl6 14014000.dsi.0: failed to write command 1
panel-boe-tv101wum-nl6 14014000.dsi.0: failed to init panel: -62
and a DSI interrupt time out.
Since I believe the problem is link to DSI/panel enabling sequence
I have try this series but that doesn't solve the issue.
I notice that when going out of deep sleep mode panel is functional.
May you have any idea to debug/solve this problem ?
Regards,
Benjamin
