OMAP: omap_device: Create clkdev entry for hwmod main_clk
Browse files Browse the repository at this point in the history 
Extend the existing function to create clkdev for every optional
clocks to add a well one "fck" alias for the main_clk of the
omap_hwmod.
It will allow to remove these static clkdev entries from the
clockXXX_data.c file.

* and main clock
* @od: struct omap_device *od
* @oh: struct omap_hwmod *oh
*
* For every optional clock present per hwmod per omap_device, this function
* adds an entry in the clkdev table of the form <dev-id=dev_name, con-id=role>

* For the main clock and every optional clock present per hwmod per

* form <dev-id=dev_name, con-id=role> if it does not exist already.
*
* The function is called from inside omap_device_build_ss(), after
* omap_device_register.
*
* This allows drivers to get a pointer to its optional clocks based on its role
* by calling clk_get(<dev*>, <role>).
* In the case of the main clock, a "fck" alias is used.
*
* No return value.
