[PATCH v5 1/4] ARM: davinci: mmc: derive version information from device name
Manjunathappa, Prakash
prakash.pm at ti.com
Tue Mar 12 10:13:54 EDT 2013
Remove specifying mmc controller IP version information via platform
data, instead specify device name so that driver derives it from
platform_device_id table. Also change the clock node name to match
the changed dev_id.
Tested on da850-evm to make sure driver loads without clk_get failures.

Since v4:
Minor nit, check on return value for failure of max-frequency property
parsing.
