From: Ondrej Jirman <megous@xxxxxxxxxx> I went through the datasheets for H6 and H5, and compared the differences. RTCs are largely similar, but not entirely compatible. Incompatibilities are in details not yet implemented by the rtc driver though. I also corrected the clock tree in H6 DTSI. This patchset is necessary for implementing the WiFi/Bluetooth support on boards using H6 SoC. There was some discussion previously of describing HOSC, DCXO and XO oscillators and clocks as part of RTC in DT, but I decided against it because it's not necessary, becuse information that would be provided as a part of DT can already be determined at runtime from RTC registers, so this woudn't add any value and would only introduce complications to the driver. See: https://patchwork.kernel.org/cover/10898083/ Please take a look.
