commit20d49e9ccf(ARM: OMAP5: voltagedomain data: Add OMAP5 voltage domain data) Introduced dummy volt data for OMAP5 with OMAP4460 voltage information. However with the fixes introduced in later patches commitcd8abed1da(ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm associated to a pwrdm) We are no longer restricted in that respect. Further, OPP voltage information is supposed to be provided by dts information. This needs to be added in future patches as various voltage modules are converted to dts. This also fixes the build breakage for voltagedomains54xx_data.c when just OMAP5 SoC is enabled: https://patchwork.kernel.org/patch/2764191/ Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Nishanth Menon <nm@ti.com> Cc: Benoit Cousson <b-cousson@ti.com> Cc: Santosh Shilimkar <santosh.shilimkar@ti.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com> Cc: linux-omap@vger.kernel.org Signed-off-by: Kevin Hilman <khilman@linaro.org>
