From: Icenowy Zheng <icenowy@xxxxxxx> Allwinner R329 has a RTC with a similar time storage with H616 but a slightly different clock part. As we have already handled the R329 RTC clocks in the CCU driver, add a compatible string to RTC driver to allow probing of the RTC. Signed-off-by: Icenowy Zheng <icenowy@xxxxxxx> Signed-off-by: Samuel Holland <samuel@xxxxxxxxxxxx> --- Resending this patch separately from Icenowy's R329 series[1] because it is also needed for D1 (which has R329 as its fallback compatible[2]), so I would like to get it in to 5.20.
