Re: drm bridge control from another driver

hi, i had added one more irq control for temperature control check in adv7511, if i call irq_proces as similar to hpd it does not work, initially if( adv7511->alert_status == connector_status_connected) no irq works. https://github.com/vinaysimha/kernel-msm/commit/8ee2b9104fa56765320d4846086d91b8

Re: drm bridge control from another driver

added the temperature alert irq handler in adv driver , in the irq calling schedule_work(&adv7511->hpd_work); , initially in the adv7511_detect , if we set status = connector_status_disconnected; later when irq handler calls the schedule work, hpd does not works. [ 55.052677] [drm] Cannot find an

Andrzej/Daniel, please suggest any input on the scenario for temperature control and dsi bridge enable/disable. On Mon, Feb 11, 2019 at 2:41 PM Vinay Simha B N wrote: > dsi2hdmi(adv7511) chip operating temperature range is -10 degC to +85 > degC. We want to enable/disable the bridge only when t

Re: drm bridge control from another driver

dsi2hdmi(adv7511) chip operating temperature range is -10 degC to +85 degC. We want to enable/disable the bridge only when temperature range is inbetween these range. We have temperature control chip to read the temp, tLow an tHigh can be set. whenever interrupt(alert) triggers we want to enablel/

drm bridge control from another driver

hi, is it possible to control the drm bridge from another driver in irq handler(enable/disable the bridge)? is there a way to control the "dpms force off" and "dpms force on" in the interrupt handler? -- regards, vinaysimha ___ dri-devel mailing list
