rockchip: timer: update for 32/64bit-aware OF_PLATDATA

2017-09-18T18:40:37+00:00

With dtoc emitting fdt64_t for addresses (and region sizes), the array
indices for accessing the reg[] array needs to be adjusted.  This
adjusts the Rockchip DM timer driver to correctly handle OF_PLATDATA
given this new structure layout.

rockchip: timer: implement timer_get_boot_us

2017-09-18T18:40:34+00:00

To make the Rockchip DM timer driver useful for the timing of
bootstages, we need a few enhancements:
 - This implements timer_get_boot_us.
 - This avoids reinitialising the timer, if it has already been
   set up (e.g. by our TPL and SPL stages). Now, we have a single
   timebase ticking from TPL through the full U-Boot.
 - This adds support for reading the timer even before the
   device-model is ready: we find the timer via /chosen/tick-timer,
   then read its address and clock-frequency, and finally read the
   timeval directly).

rockchip: timer: fix U_BOOT_DRIVER name

2017-09-05T09:04:35+00:00

When I originally added this driver, I did some careless (and in
retrospect: mindless) copy & paste for the U_BOOT_DRIVER structure
skeletion... unfortunately, the 'arc_timer' string was committed
and slipped through all reviews.

This fixes the U_BOOT_DRIVER name to read 'rockchip_rk3368_timer'
(as originally intended).

rockchip: timer: add device-model timer driver for RK3368 (and similar)

2017-08-13T15:12:36+00:00

This adds a device-model driver for the timer block in the RK3368 (and
similar devices that share the same timer block, such as the RK3288) for
the down-counting (i.e. non-secure) timers.

This allows us to configure U-Boot for the RK3368 in such a way that
we can run with the secure timer inaccessible or uninitialised (note
that the ARMv8 generic timer does not count, if the secure timer is
not enabled).
