* ARM: DRA7: Add support for IO delay configurationLokesh Vutla2015-06-12-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | On DRA7, in addition to the regular muxing of pins, an additional hardware module called IODelay which is also expected to be configured. This "IODelay" module has it's own register space that is independent of the control module. It is advocated strongly in TI's official documentation considering the existing design of the DRA7 family of processors during mux or IODelay recalibration, there is a potential for a significant glitch which may cause functional impairment to certain hardware. It is hence recommended to do muxing as part of IOdelay recalibration. IODELAY recalibration sequence: - Complete AVS voltage change on VDD_CORE_L - Unlock IODLAY config registers. - Perform IO delay calibration with predefined values. - Isolate all the IOs - Update the delay mechanism for each IO with new calibrated values. - Configure PAD configuration registers - De-isolate all the IOs. - Relock IODELAY config registers.

* ARM: DRA7: Set serial number environment variableDileep Katta2015-04-23-0/+4
| | | | | | | | | | | | | | | | | This patch populates serial number environment variable from die_id_0 and die_id_1 register values for DRA7xx boards. The function is added in omap common code so that this can be re-used. Serial# environment variable will be useful to show correct information in "fastboot devices" commands.

* ARM: OMAP5: Fix warm reset with USB cable connectedLokesh Vutla2013-05-10-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warm reset on OMAP5 freezes when USB cable is connected. Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.
