[PATCH v4 00/10] Add SDHCI support for ST Microelectronics SoCs

[Peter Griffin]

This series adds a SDHCI platform driver for ST SoCs, along with
the additional device tree bindings and configuration to enable
the controller to work properly.

Initially it supports the stih416 and stih415 SoCs, and has
been tested on a stih416-b2020 board.

regards,

Peter.

Changes since v1
- Whitespace cleanups
- Use readl_relaxed io accessor
- Add update to MAINTAINERS
- Remove reset controller code from platform driver
- Remove #ifdef around sleep ops
- Use sdhci_pltfm_clk_get_max_clock lib function
- Pass bus-width etc through board device tree node
- Remove unncessary header
- Remove / change some debug messages
- Remove final break from switch case

Changes since v2
- Update CC list with alkml and lkml lists

Changes since v3
- Rebased on v3.16-rc4
- Use sdhci_set_bus_width lib function for set_bus_width
- Remove sdhci_st_8bit_width function
- Use sdhci_set_clock lib function for set_clock
