This reverts commit 42874759d7.
This wasn't tested as a stand-alone patch, and it has build errors
without the following patches applied:
drivers/rtc/rtc-sa1100.c: In function 'sa1100_rtc_set_alarm':
drivers/rtc/rtc-sa1100.c:208: error: 'now' undeclared (first use in this function)
drivers/rtc/rtc-sa1100.c:208: error: (Each undeclared identifier is reported only once
drivers/rtc/rtc-sa1100.c:208: error: for each function it appears in.)
drivers/rtc/rtc-sa1100.c:210: error: incompatible type for argument 3 of 'rtc_next_alarm_time'
drivers/rtc/rtc-sa1100.c:211: error: 'time' undeclared (first use in this function)
So it too gets reverted to bring us back to a working point.
This reverts commit 7cea00657d.
The sa1100 cleanups fatally broke the SA1100 RTC driver - the first
hint that something is wrong are these compiler warnings:
drivers/rtc/rtc-sa1100.c:42:1: warning: "RCNR" redefined

arch/arm/mach-sa1100/include/mach/SA-1100.h:888:1: warning: this is the location of the previous definition
and the second problem, which is far more severe, are the different
register layouts, resulting in the wrong registers being read on
SA11x0 platforms. This patch adds:
#define RCNR 0x00 /* RTC Count Register */
#define RTAR 0x04 /* RTC Alarm Register */
#define RTSR 0x08 /* RTC Status Register */
#define RTTR 0x0c /* RTC Timer Trim Register */
but the SA11x0 registers are:
#define RTAR __REG(0x90010000) /* RTC Alarm Reg. */
#define RCNR __REG(0x90010004) /* RTC CouNt Reg. */
#define RTTR __REG(0x90010008) /* RTC Trim Reg. */
#define RTSR __REG(0x90010010) /* RTC Status Reg. */

In ancient times it was necessary to manually initialize the bus field of
an spi_driver to spi_bus_type. These days this is done in
spi_driver_register(), so we can drop the manual assignment.
The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,
},
};
// </smpl>

The rtc_calibration attribute allows user-space to get and set the
AB8500's RtcCalibration register. The AB8500 will then use the value in
this register to compensate for RTC drift every 60 seconds.

The resolution of msleep is related to HZ, so with HZ set to 100 any
msleep of less than 10ms will become ~10ms. This is not what we want.
Use the hrtimer-based usleep_range() and allow for some slack in the
non-critical path so we have more control of what is happening here.

There is no way to track year in the i.MX1 RTC: Days Counter register is
9-bit wide only. Attempt to save date after 1970-01-01 plus 512 days
causes endless loop in mxc_rtc_set_mmss(). Fix this by resetting year to
1970.

The patch renames puv3_rtcdrv to puv3_rtc_driver, so that modpost will know
that this is simply a list of pointers to driver functions, in which case
the section mismatch is OK. (Thanks Michal Marek)

This patch converts the driver to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.
