ARM: dts: s5pv210: add RTC 32 KHz clock in SMDKV210
[ Upstream commit 7260b363457a22b8723d5cbc43fee67397896d07 ]
The S3C RTC requires 32768 Hz clock as input which is provided by PMIC.
However the PMIC is not described in DTS at all so at least add
a workaround to model its clock with a fixed-clock.
This fixes dtbs_check warnings:
rtc@e2800000: clocks: [[2, 145]] is too short
rtc@e2800000: clock-names: ['rtc'] is too short
