Subject: [PATCH v3 0/7] mfd: add basic sun6i A31 PRCM support

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

These functions are needed to get the P2WI driver working, but more
subdevices might be added later.

Best Regards,

Boris

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
