2008-03-04sm501: add support for the SM502 programmable PLLVille Syrjala
SM502 has a programmable PLL which can provide the panel pixel clock instead of the 288MHz and 336MHz PLLs.

2008-03-04sm501: remove a duplicated tableVille Syrjala
misc_div is a subset of px_div so eliminate the smaller table. Signed-off-by: Ville Syrjala <syrjala@sci.fi> Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-11-29MFD: SM501 debug typo fixBen Dooks
Remove errnoeous x character from dev_dbg() call that stops the driver compiling under debug. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-06-24SM501: Check SM501 ID register on initialisationBen Dooks
When binding the driver, check the ID register for a valid identity, in case the SM501 is not functioning correctly. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-06-24SM501: Clock updates and checksBen Dooks
Ensure that the M1XCLK and MCLK are sourced from the same PLL (and refuse to bind the driver if they are not). Update the PCI to safe initialisation values, as 72MHz is the maximum clock for 33MHz PCI bus mastering.

2007-06-24SM501: Fix sm501_init_reg() mask/set orderBen Dooks
The order of the set and mask operation in sm501_init_reg() was setting and then masking the bits set. Correct the order so that we do not end up with 288MHz SDRAM clocks on certain systems.

2007-06-24SM501: initialise SDRAM clock before bus clocksBen Dooks
This init sequence of setting the SDRAM clock before the bus clock is recommend by Silicon Motion to stop problems with writes not sticking into registers.

2007-02-20[PATCH] mfd: SM501 core driverBen Dooks
This driver provides the core functionality of the SM501, which is a multi-function chip including two framebuffers, video acceleration, USB, and many other peripheral blocks. The driver exports a number of entries for the peripheral drivers to use.
