2016-03-14rtc: s5m: De-inline large functions to save spaceKrzysztof Kozlowski1-4/+4
Few functions were marked inline even though they were relatively large and sometimes used in multiple places. De-inline them to let the compiler decide whether optimization makes sense.

2016-01-11rtc: s5m: Make register configuration per S2MPS device to remove exceptionsKrzysztof Kozlowski1-35/+75
Before updating time and alarm the driver must set appropriate mask in UDR register. For that purpose the driver uses common register configuration and a lot of exceptions per device in the code. The exceptions are not obvious, for example except the change in the logic sometimes the fields are swapped (WUDR and AUDR between S2MPS14 and S2MPS15). This leads to quite complicated code. Try to make it more obvious by: 1. Documenting the UDR masks for devices and operations. 2. Adding fields in register configuration structure for each operation (read time, write time and alarm). 3. Splitting the configuration per S2MPS13, S2MPS14 and S2MPS15 thus removing exceptions for them.

2016-01-11rtc: s5m: Add separate field for storing auto-cleared mask in register configKrzysztof Kozlowski1-1/+5
Some devices from S2M/S5M family use different register update masks for different operations (alarm and register update). Now the driver uses common register configuration and a lot of exceptions per device in code. Before eliminating the exceptions and using specific register configuration for given device, make the auto-cleared mask a separate field. This is merely a refactoring.

RTC found in s2mps15 is almost same as one found on s2mps13 with few differences in RTC_UPDATE register fields, like: 1> Bit[4] and Bit[1] are reversed - On s2mps13 WUDR -> bit[4], AUDR -> bit[1] - On s2mps15 WUDR -> bit[1], AUDR -> bit[4] 2> In case of s2mps13, for alarm register, need to set both WDUR and ADUR high, whereas for s2mps15 only set AUDR to high. 3> On s2mps15, WUDR, RUDR and AUDR functions should never be used at the same time.

2015-09-05rtc: s5m: fix to update ctrl registerJoonyoung Shim1-0/+10
According to datasheet, the S2MPS13X and S2MPS14X should update write buffer via setting WUDR bit to high after ctrl register is written. If not, ALARM interrupt of rtc-s5m doesn't happen first time when i use tools/testing/selftests/timers/rtctest.c test program and hour format is used to 12 hour mode in Odroid-XU3 board. One more issue is the RTC doesn't keep time on Odroid-XU3 board when i turn on board after power off even if RTC battery is connected. It can be solved as setting WUDR & RUDR bits to high at the same time after RTC_CTRL register is written. It's same with condition of only writing ALARM registers, so this is for only S2MPS14 and we should set WUDR & A_UDR bits to high on S2MPS13. I can't find any reasonable description about this like fix from datasheet, but can find similar codes from rtc driver source of hardkernel kernel and vendor kernel.

2015-04-17drivers/rtc/rtc-s5m.c: allow usage on device type different than main MFD typeKrzysztof Kozlowski1-4/+6
The RTC driver supports two flavors of S5M devices: S5M8767-like and S2MPS14-like. On S2MPS13 and S2MPS14 devices the RTC module is the same so we want to re-use the existing support of S2MPS14. However device type was passed from parent MFD driver in platform data structure. This way for the S2MPS13 device the main MFD driver passed device type of 'S2MPS13X'. Instead decouple detecting of device type between main MFD and RTC driver. This allows adding support for other S2MPS14 variations (like S2MPS11 and S2MPS13) easily by adding to mfd/sec-core.c: static const struct mfd_cell s2mps13_devs[] = { { .name = "s2mps14-rtc", } }; Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
