2021-02-03rtc: zynqmp: depend on HAS_IOMEMDavid Gow1-1/+1
The Xilinx zynqmp RTC driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver not to be enable under make ARCH=um allyesconfig, even though it won't build. By adding a dependency on HAS_IOMEM, the driver will not be enabled on architectures which don't support it.

2021-01-25rtc: mrst: Remove driver for deprecated platformAndy Shevchenko1-12/+0
Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.

2020-01-27rtc: i2c/spi: Avoid inclusion of REGMAP support when not neededGeert Uytterhoeven1-2/+6
Merely enabling I2C and RTC selects REGMAP_I2C and REGMAP_SPI, even when no driver needs it. While the former can be moduler, the latter cannot, and thus becomes built-in. Fix this by moving the select statements for REGMAP_I2C and REGMAP_SPI from the RTC_I2C_AND_SPI helper to the individual drivers that depend on it. Note that the comment for RTC_I2C_AND_SPI refers to SND_SOC_I2C_AND_SPI for more information, but the latter does not select REGMAP_{I2C,SPI} itself, and defers that to the individual drivers, too.

Add partial support for the watchdog functionality of both PCF2127 and PCF2129 chips. The programmable watchdog timer is currently using a fixed clock source of 1Hz. This result in a selectable range of 1-255 seconds, which covers most embedded Linux use-cases. Clock sources of 4096Hz, 64Hz and 1/60Hz is mostly useful in MCU use-cases. Countdown timer not available when using watchdog feature.
