davinci: pass clock flags to davinci_psc_config()

2011-07-08T05:21:40+00:00

Enabling or disabling a PSC can take certain
modifiers like "disable with reset", "force
enable/disable" and "enable/disable with local
reset" apart from the regular clock gating
functionality.

Pass a flags argument to davinci_psc_config()
so these variations can be supported there.

At this time only "disable with reset" is
supported, but other functionality will be
added in subsequent patches.

davinci: dm6467/T EVM: fix setting up of reference clock rate

2011-07-06T11:18:45+00:00

The DM6467 and DM6467T EVMs use different reference clock
frequencies. This difference is currently supported by having
the SoC code call a public board routine which sets up the reference
clock frequency. This does not scale as more boards are added.

Instead, use the clk_set_rate() API to setup the reference clock
frequency to a different value from the board file.

davinci: use divide ratio limits from pll_data

2010-12-10T15:33:49+00:00

This patch modifies the sysclk rate setting code to use the divider mask
specified in pll_data.  Without this, devices with different divider ranges
(e.g. tnetv107x) fail.

davinci: clock: add support for setting sysclk rate

2010-09-24T14:40:24+00:00

Setting sysclk rate will be useful in cases where the
sysclk is not at a fixed ratio to the PLL output but
can asynchronously be changed.

This support forms the basis of attempt to keep the AEMIF
clock constant on OMAP-L138 even as PLL0 output changes
as ARM clock is changed to save power.

This patch has been tested on OMAP-L138.

davinci: clock: make 'disable unused clocks' printk debug only

2010-09-24T14:40:23+00:00

The long list of clocks being disabled on boot is noisy and not needed
for standard boots.   Make this a debug printk instead.

Davinci: psc - use ioremap()

2010-05-13T17:05:27+00:00

This patch modifies the psc and clock control code to use ioremap()ed
registers.

Davinci: configurable pll divider mask

2010-05-06T22:02:07+00:00

This patch allows socs to override the divider ratio mask by setting an
optional field (div_ratio_mask) in the pll_data structure.

Davinci: support LPSC SwRstDisable state

2010-05-06T22:02:04+00:00

The current clock control code always gates the clock (PSC state Disable = 2)
on clk_disable().  Some on-chip peripherals (e.g. LCD controller on TNETV107X)
need to be put into SwRstDisable = 0 on clock disable, to maintain
hardware sanity.

This patch extends the davinci_psc_config() arguments to pass in the desired
module state instead of a boolean enable/disable.  Further, clk_disable() now
checks for the PSC_SWRSTDISABLE clk flag before selecting the target state.

davinci: misc cleanups from sparse

2010-05-06T22:02:01+00:00

- Convert data/functions to static
- include headers for missing declarations
- pointer cleanups:  struct foo *__iomem f --> struct foo __iomem *f;
