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).

dm: timer: handle being called before dm_root is ready

2017-09-18T18:40:33+00:00

When used with bootstage recording, dm_timer_init may be called
surprisingly early: i.e. before dm_root is ready. To deal with
this case, we explicitly check for this condition and return
-EAGAIN to the caller (refer to drivers/timer/rockchip_timer.c
for a case where this is needed/used).

dm: timer: Convert to livetree

2017-09-18T18:40:33+00:00

This updates dm_timer_init to support a live tree and deals with
some fallout (i.e. the need to restructure the code such, that we
don't need multiple discontinuous #if CONFIG_IS_ENABLED blocks).

dm: x86: Allow TSC timer to be used before DM is ready

2017-09-16T06:57:44+00:00

With bootstage we need access to the timer before driver model is set up.
To handle this, put the required state in global_data and provide a new
function to set up the device, separate from the driver's probe() method.

This will be used by the 'early' timer also.

Per the Intel 64 and IA-32 Architecture Software Developer's Manual,
add the reference clock for Intel Atom Processors based on the Airmont
Microarchitecture (Braswell).

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).
