[ARM] rtc-sa1100: don't assume CLOCK_TICK_RATE to be a constant
for additional information.
Signed-off-by: Eric Miao <eric.miao@marvell.com>
|
|
As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more
a constant on PXA when multiple processors and platforms are
selected, change TIMER_FREQ in rtc-sa1100.c into a variable.
Since the code to decide the clock tick rate is re-used from
timer.c, introduce a common get_clock_tick_rate() for this.

Changes made as suggested by Eric Miao (including fix to map_io
silly mistake!).
Originally designed by Intel, now sold by Crossbow (www.xbow.com).
Very little actually on board. The patch includes sensors and
similar as found on commonly occurring daughter boards.
Some of the drivers are not in mainline as yet as they are either
part of the IIO subsystem or need a lot of work before submission.
What is the position wrt to putting them in i2c board configs etc?
Support for these boards has been maintained outside the kernel
for a long time, but now that there is a good da9030 pmic driver
available the last major hurdle no longer exists.
All comments welcomed.
The Imote2's big brother (stargate2) will follow once any problems
with this one have been cleaned up and a few bits and bobs have
been added to the da903x driver. Hopefully the cc2420 driver will
get cleaned up and submitted in the not too distant future as
well.

fbi->state change shall really be protected by fbi->ctrlr_lock, where
the change is sheltered. There is a possibility that pxafb_smart_thread
will start update the LCD panel when fbi->state == C_ENABLE, while
all other initialization isn't done.

Some smart panel requires a delay between command sequences, while PXA
LCD controller didn't provide such one, let's emulate this by software.
A software delay marker can be inserted into the command sequence, once
pxafb_smart_queue() detects this, it flushes the previous commands and
delay for a specified number of milliseconds.

For smart panels (LCD panel with internal framebuffer), the following
LCCR3 register bits have different meanings than the parallel one:
LCCR3_PCP - controls the L_PCLK_WR polarity
LCCR3_HSP - controls the L_LCLK_A0 polarity
LCCR3_VSP - controls the L_FCLK_RD polarity
To keep minimum change to the original parallel timing, the .lcd_conn
flags and 'pxafb_mode_info.sync' are re-used to reflect this:
LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP
sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP}

Group smart panel related code in a more compact fasion, avoid abused
usage of #ifdef .. #endif.
Also fix the incorrect condition in pxafb_smart_init() to decide if it
is a smart panel or not. (should be '&' instead of '|')

This patch adds HP iPAQ h5000's (h5400, h5500) basic definitions.
Kernel will able to boot, work via serial console, mount filesystems
placed on flashes and run USB gadgets (g_ether by default).
Other device drivers (frame buffer, LCD, touchscreen, backlight,
bluetooth, w1/battery, ...) are depend on SAMCOP and MediaQ
SoCs/MFDs, drivers to which will be submitted too, after massive
cleanups.
This machine will be used as "real user" for these new drivers.
This is an updated version of the patch, which contains fixes proposed on
linux-arm-kernel mailing list.

Change the halt and reboot method from gpio based to "jump
to ROM IPL beginning". This gives control back to IPL, which
without PowerOn key pressed, will put the device into deep
sleep until PowerOn is pressed for 1 second.
But this has the benefit of keeping the RTC registers across
reboots, which is good for OS change.

Following the removal of the "->policy" usage for PXA255 in patch
459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.
It also cures the runtime warning that was printed each time the
frequency was changed.
Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked
with the run/turbo thing.
Tested on an Arcom/Eurotech Viper.
