2009-11-25DaVinci: remove unneeded #include'sSergei Shtylyov1-5/+0
There have accumulated quite a lot of them after the code reorganizations... In several cases I had to replace #include <linux/dma-mapping.h> which wasn't needed directly but happened to #include <linux/err.h> which was needed.

2009-11-25davinci: DA8xx: rename 'psc_ctlr' field into 'gpsc'Sergei Shtylyov1-21/+21
Replace badly chosen 'psc_ctlr' name of the 'struct clk' field (PSC already means "Power and Sleep Controller", so the '_ctlr' postfix makes the name tautological) with technically correct 'gpsc' (Global PSC -- which contains all the module registers).

2009-11-25davinci: da830: add support for new silicon revisionsKevin Hilman1-1/+15
Newer revs of da830 silicon have different 'variant' field of the JTAG id register. Current code only supports rev 1.0 silicon. This patch adds support for rev1.1 and rev2.0 silicon and updates the 'name' strings to add a '-' between 'omap' & 'l137' to have consistent naming with da850/omap-l138. From Mark Grosen <mgrosen@ti.com>: "There are currently three silicon revisions for OMAPL137. The JTAG IDs (DEVIDR register contents) for each silicon revision are shown below: 0x0B7D F02F for silicon revision 1.0 0x8B7D F02F for silicon revision 1.1 0x9B7D F02F for silicon revision 2.0 Corresponding errata documentation will be available in the next few weeks on the ti.com website."

2009-11-25davinci: Add LCD Graphics support for DA830/OMAP-L137 EVMSteve Chen1-1/+1
Add graphics support for the Sharp LCD035Q3DG01 graphical LCD that's on the User Interface (UI) daughter card of the DA830/OMAP-L137 EVM. The LCD shares EMIFA lines with the NAND and NOR devices that are also on the UI card so those lines are shared via a couple of muxes. The muxes are controlled by the 'MUX_MODE' line on the UI card. The 'MUX_MODE' line is controlled by pin P6 of a pcf8574 i2c expander that's at i2c address 0x3f on UI card. The i2c expander is controlled using the gpio infrastructure from the board code using the 'setup()' and 'teardown()' routines. Signed-off-by: Steve Chen <schen@mvista.com> Signed-off-by: Mark A.

2009-08-26davinci: Rearrange the da830/omap-l137 macros and functionsSudhakar Rajashekhara1-35/+0
Rearrange the PINMUX macros and pinmux_setup function which are common between da830/omap-l137 and da850/omap-l138. Also, replace the da830 string in function names to da8xx. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-08-26davinci: Move the da830/omap-l137 #defines to header fileRajashekhara, Sudhakar1-15/+7
With the introduction of TI da850/omap-l138, some of the macros defined for da830/omap-l137 will be needed in da850 source file. So, move the common macros to da8xx.h header file. Also, modify the macro names from DA830_... to DA8XX_. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-08-26davinci: da8xx: Add base DA830/OMAP-L137 SoC supportMark A. Greer1-0/+1247
The da830/omap l137 is a new SoC from TI that is similar to the davinci line. Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel. Additional generalizations for future SoCs in the da8xx family done by Sudhakar Rajashekhara and Sekhar Nori.
