From: wellsk40 on 12 Aug 2010 18:00 This patch set adds support for the LPC32xx built-in RTC. This is a persistent RTC with alarm on it's own power domain and a dedicated oscillator. UIE emulation is used for *_UIE_* ioctls. The patch can be pulled from: git://git.lpclinux.com/linux-2.6-lpc rtc-lpc32xx_v3 v3 includes updates from the initial review of the RTC driver and updates from v2. ...Fingers crossed... Changes since v2: RTC register macros now prefixed with LPC32XX_ Changed alarm_enable type to unsigned char to match the type in the struct rtc_wkalrm (enable) Set pending flag to correct state in read-alarm function Change the alarm read failure message to a warning Regardless of the state of the alarm enable flag passed into set_alarm, the alarm fire value is updated. Previously, this was only updated when the alarm enable flag was set Added braces for else clauses with a single statement if the previous if clause had them Cleared platform data pointer in rtc structure on error and remove Changes since v1: Fixed spaces/tabbing in lpc32xx entry in Kconfig/Makefile Remove improper enable for rtc->alarm_enabled Removed typecast on rtc structure in irq handler Switch to resource managed (devm_) variants of kzalloc and other functions in probe. Updated remove based on these changes. Disabled alarm on probe instead of keeping current register settings. No changes for suspend. Allowed driver to continue operation without wakeup or alarm irq if the rtc irq request failed. Relocated module_init and _exit macros to just after it's associated function Passed a NULL pointer to .driver.pm in platform driver structure instead of a list of NULL functions. Added MODULE_ALIAS -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
