Subject: [PATCH] overlays: Add PCF85063 and PCF85063A to i2c-rtc
|
|
|
|
Add support for the PCF85063 and PCF85063A RTC devices to the
|
|
i2c-rtc overlay.
|
|
|
|
Also enable the device to be used on i2c0 (i2c_vc) on GPIOs 0&1 (use
|
|
parameter "i2c0") and GPIOs 44 & 45 (use parameter "i2c_csi_dsi").
