| Series | [1/2] ARM: dts: am335x-myirtech: Add an external clock oscillator for CPU RTC | expand |
* Alexander Shiyan <eagle.alexander923@gmail.com> [220427 11:16]: > The CPU RTC has an external crystal, so to keep time, let's define > it for devicetree. I've applied both patches into omap-for-v5.19/dt thanks. Tony
