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

2010-01-19OMAP3: hwmod: Adding flag to prevent caching of sysconfig register.Thara Gopinath
In the current implementation the sysconfig value is read into _sysc_cache once and an actual update to the sysconfig register happens only if the new value paased is differnt from the one in _sysc_cache. _sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set. This can lead to the follwing issue if off mode is enabled in modules which employs "always-retore" mechanism of context save and restore. a. The module sets the sysconfig register through omap_device_enable. Here _sysc_cache is updated with the value written to the sysconfig register and left. b. The power domain containig the module enters off mode and the module context is lost. c. The module in use becomes active and calls omap_device_enable to enable itself. Here a read of sysconfig register does not happen as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written to the sysconfig register will be same as the one written in step a. Since _sysc_cache reflects the previous written value an update of the sysconfig register does not happen. This means in modules which employs "always-restore" mechanism after off , the sysconfig regsiters will never get updated. This patch introduces a flag SYSC_NO_CACHE which if set ensures that the sysconfig register is always read into _sysc_cache before an update is attempted. This flags need to be set only by modules which does not do a context save but re-initializes the registers every time the module is accessed. This includes modules like i2c, smartreflex etc. Signed-off-by: Thara Gopinath <thara@ti.com> [paul@pwsan.com: tweaked to apply on a different head, added flag comment] Signed-off-by: Paul Walmsley <paul@pwsan.com>

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.
