[U-Boot] [PATCH v3 0/4] mmc: sdhci: Add support for frequency constrained peripheral interfaces

[stefan.herbrechtsmeier at weidmueller.de]

From: Stefan Herbrechtsmeier <stefan.herbrechtsmeier at weidmueller.de>


The sdhci controller assumes that the base clock frequency is fully
supported by the peripheral and doesn't support hardware limitations.
Distinguish between base clock of the host controller and maximal
supported peripheral clock frequency of the peripheral interface.
This is needed for the zynq platform to support two sdhci ports with
different IO routings.

Changes in v3:
- Rename arguments of sdhci_setup_cfg function from max_clk/min_clk to f_max/f_min

Changes in v2:
- Remove unused index from get uart clock function
- Remove unused index from get sdio clock function
- Introduce common get clock function

Stefan Herbrechtsmeier (4):
  mmc: sdhci: Distinguish between base clock and maximum peripheral
    frequency
  serial: zynq: Remove unused index from get uart clock function
  mmc: zynq: Determine base clock frequency via clock framework
  mmc: zynq: Add fdt max-frequency support
