* davinci: PSC: Clear bits in MDCTL reg before setting new bitsMark A. Greer2009-04-271-11/+6
| | | | | | | | | | Clear any set bits in the 'NEXT' field of the MDCTL register in the Power and Sleep Controller (PSC) before setting any new bits. This also allows some minor cleanup by removing some no longer needed lines of code. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* davinci: gpio bugfixesDavid Brownell2009-04-272-36/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the DaVinci GPIO code to work better on non-dm6446 parts, notably the dm355: - Only handle the number of GPIOs the chip actually has. So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* davinci: add arch_ioremap() which uses existing static mappingsKevin Hilman2009-04-2312-98/+105
| | | | | | | | | | | Add arch-specific ioremap() which uses any existing static mappings in place of doing a new mapping. From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman2009-04-2310-234/+402
| | | | | | | | | | | | | | | | | | | This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.
