Bartosz Golaszewski d470df3bc5 ARM: davinci: WARN_ON() if clk_get() fails 
Currently the timer code checks if the clock pointer passed to it is
good (!IS_ERR(clk)). The new clocksource driver expects the clock to
be functional and doesn't perform any checks so emit a warning if
clk_get() fails. Apply this to all davinci platforms.

Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h 
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Found with this grep:

without SPARSE_IRQ as it's then expected to define NR_IRQS and is

Commit 587f7a694f ("gpio: davinci: Use dev name for label and

DaVinci board files use the legacy GPIO API with hard-coded GPIO line
numbers. Use the new fields in struct davinci_gpio_platform_data to
manually set the GPIO base to 0.

dm646x is a special case because we need to handle different ref_clk rates

of the clocks are registered.

Sekhar Nori 933b11aeed ARM: davinci: fix build break because of undeclared dm365_evm_snd_data 
commit 6bce5efd44 ("ARM: davinci: remove unused davinci-i2s pdata")
removed all instances of davinci-i2s pdata. However, on DM365 EVM,
the same platform data is passed to the voicecodec present on that
device.

This causes build breakage when voicecodec support is enabled:

arch/arm/mach-davinci/board-dm365-evm.c:764:17: error: 'dm365_evm_snd_data' undeclared (first use in this function)

voicecodec driver does not use the platform data as well, and
it is safe to remove it.
