2010-02-17omap: Remove DEBUG_FS dependency for mux name checkingRanjith Lohithakshan
The check for a valid mux name should be performed regardless of whether DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] last sysfs file: Modules linked in: CPU: 0 Not tainted (2.6.33-rc8 #10) PC is at strcmp+0x18/0x40 LR is at omap_mux_init_signal+0x68/0x14c ... This fixes the issue currently seen with boards not booting up if DEBUG_FS is not enabled in defconfig. Note that the earlier ifndef + ifdef now becomes simpler ifdef else: If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected, we only want the GPIO to mux register mapping.

David Binderman ran the sourceforge tool cppcheck over the source code of the new Linux kernel 2.6.33-rc6: [./arm/mach-omap2/mux.c:492]: (error) Buffer access out-of-bounds 13 characters + 1 digit + 1 zero byte is more than 14 characters.

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. Note that additionally the uninitialized pins need to be skipped on 34xx. Based on an earlier patch by Allen Pais <allen.pais@ti.com>.

2010-01-19omap: Fix functions for dynamic remuxing of pinsTony Lindgren
Make the omap_mux_read and write available for board code, and rename omap_mux_set_board_signals into omap_mux_write_array. Also add the related prototypes and comments into mux.h. In some cases we want to change the signals dynamically, mostly for power management. Note that we cannot use the signal names as they are set __init to save memory.

2010-01-19omap: Fix cmdline muxingTony Lindgren
Looks like cmdline muxing got broken at some point when we decided to limit muxing to __init code. Currently omap_mux_entry list is not yet initialized when we try to initialize cmdline muxing. Fix this by calling omap_mux_init_list() before calling omap_mux_set_cmdline_signals().

2009-12-11omap: mux: Add new style pin multiplexing code for omap3Tony Lindgren
Initially only for 34xx. This code allows us to: - Make the code more generic as the omap internal signal names can stay the same across omap generations for some devices - Map mux registers to GPIO registers that is needed for dynamic muxing of pins during off-idle - Override bootloader mux values via kernel cmdline using omap_mux=some.signa1=0x1234,some.signal2=0x1234 - View and set the mux registers via debugfs if CONFIG_DEBUG_FS is enabled Cc: Mike Rapoport <mike@compulab.co.il> Cc: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Added runtime programming for the differences in EHCI interface between OMAP3EVM revisions (Rev >= E) and (Rev < E). Changes: - EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E uses GPIO pin 135. - Rev >= E uses EHCI Vbus enable GPIO22 line. - Rev >= E uses GPIO61 to select EHCI port either on main board or on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have EHCI port on main board. - Currently GPIO61 it programmed to enable EHCI port on main board only. Signed-off-by: Ajay Kumar Gupta <ajay.gupta@ti.com>

2009-09-24omap: Fix MMC gpio_wp for BeagleBoard C2 and aboveJarkko Nikula
Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect. However, this signal has been changed to pad AG9 in board revision C2.

2009-07-24OMAP3: Setup MUX settings for SDRC CKE signalsJean Pihet
This patches ensures the MUX settings are correct for the SDRC CKE signals to SDRAM. This allows the self-refresh to work when 2 chip-selects are in use. A warning is thrown away in case the initial muxing is incorrect, in order to track faulty or old-dated bootloaders. Note: The CONFIG_OMAP_MUX and CONFIG_OMAP_MUX_WARNINGS options must be enabled for the mux code to have effect.

Add minimal omap3430 support based on earlier patches from Syed Mohammed Khasim. Also merge in omap34xx SRAM support from Karthik Dasu and use consistent naming for sram init functions. Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.

2008-04-14ARM: OMAP2: Change 24xx to use new register accessPaul Walmsley
This patch changes 24xx to use new register access, except for clock framework. Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses. Also note that sleep.S removes some unused registers addresses. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
