* rtc: fix driver data issues in several rtc driversAlessandro Zummo2009-12-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | Herton Ronaldo Krzesinski recently raised up, and fixed, an issue with the rtc_cmos driver, which was referring to an inconsistent driver data. This patch ensures that driver data registration happens before rtc_device_register().

* drivers/rtc/: use bcd2bin/bin2bcdAdrian Bunk2008-10-201-10/+10
| | | | | | | | | | | Change drivers/rtc/ to use the new bcd2bin/bin2bcd functions instead of the obsolete BCD_TO_BIN/BIN_TO_BCD/BCD2BIN/BIN2BCD macros.

| | | | | | | | | | | | Fix bogus #include in rtc-pcf8583, so it compiles on platforms that don't support PC clone RTCs. (Original issue noted by Adrian Bunk.)

* rtc-pcf8583: Don't abuse I2C_M_NOSTARTJean Delvare2008-02-061-17/+7
| | | | | | | | | | | | The rtc-pcf8583 driver is using the I2C_M_NOSTART flag but shouldn't. This flag is only meant for broken chips and the PCF8583 RTC chip is not one of these.

* rtc-pcf8583: Check for i2c adapter functionalityJean Delvare2007-10-161-0/+3
| | | | | | | | | | | Not all i2c adapters support I2C-level messaging. Check that the adapter does before probing for a PCF8583 chip, as the driver makes use of i2c_transfer and i2c_master_send.

* [ARM] rtc-pcf8583: Final fixes for this RTC on RiscPCRussell King2007-03-041-1/+1
| | | | | | | | | | | | | | Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c. Also, since this driver also contains Acorn RiscPC specific code for obtaining the current year from the SRAM (and updating the platform specific checksum when writing new data back) this is NOT a platform independent driver. Document it as such, and update the dependencies to reflect this fact. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] rtc-pcf8583: correct month and year offsetsRussell King2007-03-041-5/+6

* [ARM] rtc-pcf8583: don't use BCD_TO_BIN/BIN_TO_BCDRussell King2007-03-041-10/+10
| | | | | | | | | | Both BCD_TO_BIN(x) and BIN_TO_BCD(x) have an unexpected side-effect - not only do they return the value as expected, they _modify_ their argument in the process. Let's play it safe and avoid these macros. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [PATCH] constify rtc_class_ops: update driversDavid Brownell2006-10-011-1/+1
| | | | | | | | | | Update RTC framework so that drivers can constify their method tables, moving them from ".data" to ".rodata". Then update the drivers.

* [PATCH] drivers/acorn/char/pcf8583.[hc] vs. RTC subsystemG. Liakhovetski2006-06-251-0/+394
A port of the driver for the pcf8583 i2c rtc controller to the generic RTC framework by Alessandro Zummo. Based on drivers/acorn/char/{pcf8583.[hc],i2c.c}. Hopefully, acorn can be converted too to use this driver in the future. Signed-off-by: G.
