support rtc PCF2131 for imx93.
Signed-off-by: Joy Zou joy.zou@nxp.com --- Changes in v4: 1. remove arch/arm/dts/imx93_11x11_evk.dts change because it can sync from kernel dts. 2. add the RTC support to the -u-boot.dtsi. 3. assign the rtc0 to rtc@53 in order to avoid date reset fail.
Changes in v3: 1. remove arch/arm/dts/imx93.dtsi modification because this change have existed.
Changes in v2: 1. use the flag bootph-pre-ram instead of uboot,dm-spl. --- arch/arm/dts/imx93-11x11-evk-u-boot.dtsi | 34 ++++++++++++++++++++++++ 1 file changed, 34 insertions(+)
