2010-02-15omap: Rename mmc-twl4030 files to hsmmcAdrian Hunter
mmc-twl4030.[ch] no longer has any dependency on twl4030 and should be renamed to reflect that. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-15omap_hsmmc: Move gpio and regulator control from board fileAdrian Hunter
This patch moves the setup code for GPIO's and Voltage Regulators from the board file mmc-twl4030.c to the driver omap_hsmmc.c. PBIAS and other system control configuration remains in the board file. Moving GPIO code to the driver makes the board initialisation code independent of when GPIO's are defined. That makes the board initialisation now entirely independent of its original twl4030 roots. Moving Voltage Regulator code to the driver allows for further development of regulator support in the core MMC code. It also permits the MMC core to be compiled as a module, because the board code no longer calls MMC core functions.

2010-02-15omap3: Add support for flash on 3430SDP boardVimal Singh
This patch adds support for flashes on 3430SDP boards. All three NAND, NOR and OneNAND are supported. I have tested it on 3430SDP (ES2 and ES3.1). This patch can be treated as an example to "how to utilize": 'gpmc-nand.c' and 'board-sdp-flash.c'. Similar patches can be created for 2430sdp and 3630sdp or any other similar board.

2010-02-15omap3: SDP: Introducing 'board-sdp-flash.c' for flash initVimal Singh
This patch adds 'board-sdp-flash.c', which could be utilized by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp). This file does initialization for all three flash devices present in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number dynamically using switch setting information (S8: 1-4). This also expects partition information from core board files (for ex: board-3430sdp.c). Which allows to choose different default partitions for different boards. A new structure is created for this purpose: 'flash_partitions' in 'mach/board-sdp.h'. This has two members: 1. struct mtd_partition *parts 2. int nr_parts A board file is expected to fill this structure and pass it to 'sdp-flsash-init'. Partition information should be passed in structure array of 'flash_partitions'. Partition information should be passed in below sequence in array: NOR OneNAND NAND Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-02-15omap: McBSP: Introduce caching in register write operationsJanusz Krzysztofik
Determine cache size required per McBSP port at init time, based on processor type running on. Allocate space for storing cached copies of McBSP register values at port request. Modify omap_msbcp_write() function to update the cache with every register write operation. Modify omap_mcbsp_read() to support reading from cache or hardware. Update MCBSP_READ() macro for modified omap_mcbsp_read() function API. Introduce a new macro that reads from the cache. Tested on OMAP1510 based Amstrad Delta using linux-omap for-next, commit fb7380d70e041e4b3892f6b19dff7efb609d15a4 (2.6.33-rc3+ dated 2010-01-11).

2010-02-03omap: Disable serial port autoidle by defaultTony Lindgren
Currently the omap serial clocks are autoidled after 5 seconds. However, this causes lost characters on the serial ports. As this is considered non-standard behaviour for Linux, disable the timeout. Note that this will also cause blocking of any deeper omap sleep states. To enable the autoidling of the serial ports, do something like this for each serial port: # echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout # echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout ...

2010-02-03omap: Fix 3630 mux errorsTony Lindgren
3630 has more mux signals than 34xx. The additional pins exist in omap36xx_cbp_subset, but are not initialized as the superset is missing these offsets. This causes the following errors during the boot: mux: Unknown entry offset 0x236 mux: Unknown entry offset 0x22e mux: Unknown entry offset 0x1ec mux: Unknown entry offset 0x1ee mux: Unknown entry offset 0x1f4 mux: Unknown entry offset 0x1f6 mux: Unknown entry offset 0x1f8 mux: Unknown entry offset 0x1fa mux: Unknown entry offset 0x1fc mux: Unknown entry offset 0x22a mux: Unknown entry offset 0x226 mux: Unknown entry offset 0x230 mux: Unknown entry offset 0x22c mux: Unknown entry offset 0x228 Fix this by adding the missing offsets to omap3 superset.

2010-01-29OMAP2/3/4 clock: rename and clean the omap2_clk_init() functionsPaul Walmsley
Rename the omap2_clk_init() in the OMAP2, 3, and 4 clock code to be omap2xxx_clk_init(), omap3xxx_clk_init(), etc. Remove all traces of the (commented) old virt_prcm_set code from omap3xxx_clk_init() and omap4xxx_clk_init(), since this will be handled with the OPP code that is cooking in the PM branch. After this patch, there should be very little else in the clock code that blocks a multi-OMAP 2+3 kernel.

2010-01-29OMAP3 clock: split out DPLL3 M2 divider functions into ↵Paul Walmsley
mach-omap2/clkt34xx_dpll3m2.c Split the DPLL3 M2 divider clock functions out of clock34xx.c and move them into mach-omap2/clkt34xx_dpll3m2.c. This is intended to make the clock code easier to understand, since all of the functions needed to manage the OMAP3 DPLL3 M2 divider are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for the DPLL3 M2 clock alone. This should reduce unnecessary console noise when debugging DVFS. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap34xx/ directory, rather than shared with other chip types that don't use this clock type. This patch also lays the groundwork to skip compilation of this code on OMAP3 chips that don't support DVFS (e.g., AM35xx) via the Makefile, rather than via #ifdefs.
