rtc: cmos: prevent kernel warning on IRQ flags mismatch

2016-01-11T19:38:50Z

The Microsoft Surface 3 tablet shares interrupt line between RTC and one of SPI controllers. However, the rtc_cmos driver doesn't allow shared interrupts and user sees the following warning genirq: Flags mismatch irq 8. 00000080 (8086228E:02) vs. 00000000 (rtc0) ... [] pxa2xx_spi_probe+0x151/0x600 [spi_pxa2xx_platform] Allow RTC driver to use shared interrupts. Seems we are on the safe side to do just this simple change since cmos_interrupt() handler checks for the actual hardware status anyway.

rtc: s5m: Make register configuration per S2MPS device to remove exceptions

2016-01-11T19:21:55Z

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.

rtc: s5m: Add separate field for storing auto-cleared mask in register config

2016-01-11T19:21:45Z

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: s5m: Cleanup by removing useless 'rtc' prefix from fields

2016-01-11T19:21:35Z

Remove the 'rtc' prefix from some of the fields in struct s5m_rtc_reg_config because it is obvious - this is a RTC driver. No functional changes. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Alim Akhtar Tested-by: Alim Akhtar Signed-off-by: Alexandre Belloni

rtc: Replace simple_strtoul by kstrtoul

2016-01-11T19:20:02Z

The simple_strtoul function is obsolete. This patch replace it by kstrtoul. Since kstrtoul is more strict, it permits to filter some invalid input that simple_strtoul accept. For example: echo '1022xxx' > /sys/devices/pnp0/00:03/rtc/rtc0/max_user_freq cat /sys/devices/pnp0/00:03/rtc/rtc0/max_user_freq 1022 Signed-off-by: LABBE Corentin Signed-off-by: Alexandre Belloni
