This is an add-on series to the main SoC Sparx5 series
(Message-ID: <20200615133242.24911-1-lars.povlsen@microchip.com>

It adds eMMC support for Sparx5, by adding a driver for the SoC SDHCI
controller, DT configuration and DT binding documentation.

Changes in v4:
- Disable clock if sdhci_add_host() fails
- Remove dev_err if sdhci_add_host() fails

Changes in v3:
- Add dt-bindings for property "microchip,clock-delay"
- Enforce "microchip,clock-delay" valid range in driver
- Removed a noisy pr_debug() in sdhci_sparx5_adma_write_desc()

Changes in v2:
- Changes in driver as per review comments
 - Drop debug code
 - Drop sysfs code
 - use usleep_range()
 - use mmc_hostname() in pr_debug()
 - Remove deactivated code
 - Minor cosmetics
