The avs drivers are all SoC specific drivers that doesn't share any code. Instead they are located in a directory, mostly to keep similar functionality together. From a maintenance point of view, it makes better sense to collect SoC specific drivers like these, into the SoC specific directories. Therefore, let's move the smartreflex driver for OMAP to the ti directory. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Reviewed-by: Nishanth Menon <nm@ti.com> Signed-off-by: Rafael J.

user must write 1 to

Optionally autocompensation can be enabled in the kernel

which an be passed as platform data to the smartreflex driver.

Say Y if you want to reset unused clocks during boot.
|
|
This option saves power, but assumes all drivers are
|
|
using the clock framework. Broken drivers that do not
|
|
yet use clock framework may not work with this option.
|
|
If you are booting from another operating system, you
|
|
probably do not want this option enabled until your
|
|
device drivers work properly.

Select this option if you want to enable the OMAP 32KHz timer.
|
|
This timer saves power compared to the OMAP_MPU_TIMER, and has
|
|
support for no tick during idle. The 32KHz timer provides less
|
|
intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
|
|
currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
|
|
|
|
On OMAP2PLUS this value is only used for CONFIG_HZ and
|
|
CLOCK_TICK_RATE compile time calculation.
|
|
The actual timer selection is done in the board file
|
|
through the (DT_)MACHINE_START structure.
