[PATCH v5 2/5] OMAP4: Adding voltage driver support

Thara Gopinath
2010-12-20T17:00:56Z

OMAP4 has three scalable voltage domains vdd_mpu, vdd_iva
and vdd_core. This patch adds the voltage tables and other
configurable voltage processor and voltage controller
settings to control these three scalable domains in OMAP4.

Signed-off-by: Thara Gopinath <thara@ti.com>

This patch has 9 checkpatch.pl above 80-chars warnings for
the definitions of omap44xx_vdd_mpu_volt_data, omap44xx_vdd_iva_volt_data
and omap44xx_vdd_core_volt_data.
IMHO splitting of the entries in these structures affects
readability and looks very ugly. Hence they are left as is.
