Re: [U-Boot] [PATCH V3] fsl: esdhc: support driver model

Hi Peng,

Support Driver Model for fsl esdhc driver.

1. Introduce a new structure struct fsl_esdhc_priv
2. Refactor fsl_esdhc_initialize which is originally used by board code.
   • Introduce fsl_esdhc_init to be common usage for DM and non-DM
   • Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part.
   • The original API for board code is still there, but we use 'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it.
3. All the functions are changed to use 'struct fsl_esdhc_priv', except fsl_esdhc_initialize.
4. Since clk driver is not implemented, use mxc_get_clock to geth the clk and fill 'priv->sdhc_clk'.

Has been tested on i.MX6UL 14X14 EVK board: " =>dm tree .... simple_bus [ + ] | `-- aips-bus@02100000 mmc [ + ] | |-- usdhc@02190000 mmc [ + ] | |-- usdhc@02194000 .... => mmc list FSL_SDHC: 0 (SD) FSL_SDHC: 1 (SD) "

After pulling in device tree files from the mainline kernel, I was able to test this on a SABRE Lite, so you can add my:

Is somebody prepping patches to pull in support for i.MX6DQ?

Please advise,
