[V1 3/3] RTC: sa1100: support sa1100, pxa and mmp soc families

Since the regmap of rtc on sa1100, pxa and mmp Marvell soc families are
almost the same, so re-arch the rtc-sa1100 to support them.

Hi Jett.Zhou,
That's a very good work.

...zip...

 static int sa1100_rtc_remove(struct platform_device *pdev)
 {
-	struct rtc_device *rtc = platform_get_drvdata(pdev);
+	struct sa1100_rtc *sa1100_rtc = platform_get_drvdata(pdev);
 
-	if (rtc)
-		rtc_device_unregister(rtc);
+	rtc_device_unregister(sa1100_rtc->rtc);
+	if (sa1100_rtc->id == RTC_MMP) {
+		clk_unprepare(sa1100_rtc->clk);
+		clk_disable(sa1100_rtc->clk);
+	}
 
+	spin_lock_irq(&sa1100_rtc->lock);
+	iounmap(sa1100_rtc->base);
+	spin_unlock_irq(&sa1100_rtc->lock);

Why the spin lock here ?

Cheers.
