* ARM: omap2+: usb-tusb6010.c: Cleaning up variable is set more than onceRickard Strandqvist2014-07-071-1/+0
| | | | | | | | | A struct member variable is set to the same value more than once This was found using a static code analysis program called cppcheck. Signed-off-by: Rickard Strandqvist <rickard_strandqvist@spectrumdigital.se> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2+: Convert TUSB to use gpmc_cs_program_settings()Jon Hunter2013-04-011-24/+19
| | | | | | | | | Convert the OMAP2+ TUSB code to use the gpmc_cs_program_settings() function for configuring the various GPMC options instead of directly programming the CONFIG1 register. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>
* ARM: OMAP2+: Add structure for storing GPMC settingsJon Hunter2013-04-011-8/+11
| | | | | | | | | | | | | | | The GPMC has various different configuration options such as bus-width, synchronous or asychronous mode selection, burst mode options etc. Currently, there is no central structure for storing all these options when configuring the GPMC for a given device. Some of the options are stored in the GPMC timing structure and some are directly programmed into the GPMC configuration register. Add a new structure to store these options and convert code to use this structure. Adding this structure will allow us to create a common function for configuring these options.

* ARM: OMAP2+: tusb6010: generic timing calculationAfzal Mohammed2012-11-091-138/+44

* ARM: OMAP2+: gpmc: handle additional timingsAfzal Mohammed2012-11-091-1/+2
| | | | | | | | | | | | | | | Configure busturnaround, cycle2cycledelay, waitmonitoringtime, clkactivationtime in gpmc_cs_set_timings(). This is done so that boards can configure these parameters of gpmc in Kernel instead of relying on bootloader. Also configure bool type timings like extradelay. This needed change to the existing users that were configuring clk activation time and extra delay by directly writing to registers. Thanks to Tony for making me aware of users of clk activation and being kind enough to test the modified one. Signed-off-by: Afzal Mohammed <afzal@ti.com>

Thanks to Jarkko Nikula for some comments on the sscanf() warnings. It seems that the kernel sscanf() ignores the field width anyway for the %d format, so those changes have been dropped from this second version.
