ARM: OMAP: omap_device: Add omap_device_get_by_hwmod_name
An API which translates a standard hwmod name to corresponding platform_device is useful for drivers when they need to look up the device associated with a hwmod name to map back into the device structure pointers. These ideally should be used by drivers in mach directory. Using a generic hwmod name like "gpu" instead of the actual device name which could change in the future, allows us to: a) Could in effect help replace apis such as omap2_get_mpuss_device, omap2_get_iva_device, omap2_get_l3_device, omap4_get_dsp_device, etc.. b) Scale to more devices rather than be restricted to named functions c) Simplify driver's platform_data from passing additional fields all doing the same thing with different function pointer names just for accessing a different device name. Signed-off-by: Nishanth Menon <nm@ti.com> [b-cousson@ti.com: Adapt it to the new pdev pointer inside od, remove the unneeded helpers, and fold the next patch here] Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
