[PATCH v4 0/7] mfd: add basic sun6i A31 PRCM support

[Boris BREZILLON]

Hello,

This patch series adds support for some functions provided by the PRCM
(Power/Reset/Clock Management) unit:
- AR100, AHB0 and APB0 clocks
- APB0 reset controller

Best Regards,

Boris

Changes since v3:
- split clk drivers into 3 different drivers: ar100, apb0 and apb0_gates
- fix indentation
- add comments to the clk drivers
- select the MFD_SUN6I_PRCM when compiling for SUN6I arch

Changes since v2:
- use devm_ioremap_resource instead of devm_request_and_ioremap
- remove unnecessary header inclusions
- remove info trace when the probe succeed
- rename apb0_timer01 clk into apb0_timer

Changes since v1:
- fix prcm and prcm-clks DT documentation
- remove unneeded iounmap and kfree calls from sunxi_reset_remove function
- rework the AR100 clk implementation
