In order to migrate the dmtimer driver to support device-tree I found that it
was first necessary to clean-up the timer platform data. The goal of this
series is to simplify the timer platform data structure from ...
struct dmtimer_platform_data {
int (*set_timer_src)(struct platform_device *pdev, int source);
int timer_ip_version;
u32 needs_manual_reset:1;
bool reserved;
bool loses_context;
int (*get_context_loss_count)(struct device *dev);
};
to ...
struct dmtimer_platform_data {
int (*set_timer_src)(struct platform_device *pdev, int source);
u32 timer_capability;
};
... where timer_capability is a bit mask that indicates the timer features
supported and uses the HWMOD timer capabilities flags described in
plat/dmtimer.h. For OMAP2+ devices this allows us to read the timer
capabilities from the HWMOD data and for OMAP1 devices the flags are simply
populated by the timer initialisation code. Eventually, the aim is to read the
timer capabilities from the device tree blob.
This series includes some fixes as well as clean-up. For instance OMAP1 dmtimer
support is currently completely broken and so I have included a fix for this.
If it is preferred to split the series into fixes and clean-up I can do that.
This series is based upon the current linux-omap master branch (3.5-rc1). I have
built both omap1 and omap2plus configurations as well as booted the respective
kernels on the omap5912 OSK (omap1), OMAP3430 Beagle and OMAP4460 PANDA.
