[PATCH v9 00/10] rtc: at91sam9: add DT support

[Boris BREZILLON]

Hello,

This patch series adds DT support to the atmel at91sam9 RTC driver.

It also removes any machine specific inclusions to prepare the migration
to multi platform kernel support, and retain the slow clock to prevent
the CCF from disabling it at the end of boot.
  
Best Regards,

Boris

Changes since v8:
 - fix DT documentation
 - add missing '\n' in dev_err messages

Changes since v7:
 - fix typo
 - fix sclk_rate test
 - state that RTC_DRV_AT91SAM9_RTT and RTC_DRV_AT91SAM9_GPBR are no longer
   used when booting a DT board

Changes since v6:
 - fix typos
 - add missing commit messages
 - rework the Kconfig description

Changes since v5:
 - replace 'rtc' by 'rtt' where appropriate
 - fix commit messages

Changes since v4:
 - add a TODO comment to remember removing non DT board support code

Changes since v3:
 - add GPBR DT bindings doc
 - fix a coding style issues
 - add Alexandre's Acked-by

Changes since v2:
 - make use of syscon/regmap to avoid directly requesting/mapping a GPBR
   memory region in the RTT driver

Changes since v1:
 - remove non CCF specific case by adding the appropriate clk_lookup
   entries in arch/arm/mach-at91/<soc-name>.c files
