Subject: [PATCH] overlays: Improve the i2c-rtc,i2c_csi_dsi option
|
||
|
|
|
||
|
|
The i2c_csi_dsi parameter of the i2c-rtc overlay (added for the CM4IO
|
||
|
|
board) causes the RTC devices to be probed on the I2C0 bus appearing
|
||
|
|
on GPIOs 44 and 45. However, it didn't enable the other nodes necessary
|
||
|
|
for it to work - "dtparam=i2c_vc=on" was also required.
|
||
|
|
|
||
|
|
Fix that.
