clocksource: convert ARM 32-bit up counting clocksources

2011-05-23T17:04:51+00:00

Convert ixp4xx, lpc32xx, mxc, netx, pxa, sa1100, tcc8k, tegra and u300
to use the generic mmio clocksource recently introduced.

arm: tcc8k: Fix bus clock calculation

2011-03-11T09:06:06+00:00

There are two dividers used to derive bus clock from system clock:
system clock is divided by SCKDIV+1, then by BCKDIV+1. SCKDIV divider
has been ignored up to now, which is no problem as long as it is 0.

Take SCKDIV into account for bus clock calculation.

arm: tcc8k: Fix indent, coding syle

2011-03-11T09:06:06+00:00

Remove double definition of ACLKUSBH, change parameter name in
root_clk_disable, as there is no reason to have a different name than
in root_clk_enable.

No functional change.

arm: tcc8k: Avoid reading clock register twice

2011-03-11T09:06:06+00:00

There is no reason why in case of PLL2 the configuration register
should be read twice, while for PLL0/1 using the value previously read
is used. Do the same for PLL2.

arm: tcc8k: Fix clock rate calculation

2011-03-11T09:06:06+00:00

The calculation of the best divider value for a requested clock rate
always returned a value that was slightly too large. It was also not
protected against possible divisions by zero.

Request for very low, but non zero rates would cause the ACLK divisor
field to overflow. Catch this situation by using the maximum value.

The internal function aclk_set_rate() calculates the correct divider
value, but doesn't write it back to the register. Add the write back.

arm: tcc8k: Choose PLL settings conforming to board layout

2011-03-11T09:06:05+00:00

The evaluation board is driven with 1.2V core voltage, so system clock
must not exceed 192 MHz, bus clock must not exceed 110 MHz. Choose
appropriate values and set DTCMWAIT accordingly. Adapt UART setting to
avoid console log interruption and wait for the specified locking time
of 300us to pass.

ARM: P2V: avoid initializers and assembly using PHYS_OFFSET

2011-02-17T23:27:30+00:00

As PHYS_OFFSET will be becoming a variable, we can't have it used in
initializers nor assembly code.  Replace those in generic code with
a run-time initialization.  Replace those in platform code using the
individual platform specific PLAT_PHYS_OFFSET.
