2012-01-27ARM: davinci: update mdio bus nameSekhar Nori1-1/+1
Commit 5a05a8200a4359ef2bfe9094c137dee35cfdd516 ("davinci_emac: use an unique MDIO bus name") introduced during the v3.3 merge window updated the davinci mdio bus name to make it unique. Update the bus name in board files which use DaVinci MDIO bus to match the new name. Without this PHY is not detected with error like: PHY 0:01 not found net eth0: could not connect to phy 0:01 Tested on DM365 and DA850 EVMs. Cc: Florian Fainelli <florian@openwrt.org> Cc: David S.

2011-12-05ARM: davinci: da850 evm: change audio edma event queue to EVENTQ_0Manjunathappa, Prakash1-1/+1
On OMAP-L138 platform, EDMA event queue 0 should be used for audio transfers so that they are not starved by video data moving on event queue 1. Commit 48519f0ae03bc7e86b3dc93e56f1334d53803770 (ASoC: davinci: let platform data define edma queue numbers) had a side-effect of changing this behavior by making the driver actually honor the platform data passed.

2011-09-11mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris1-1/+1
Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH.

2011-09-11mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris1-1/+1
This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

2011-09-07ARM: davinci: da850 EVM: read mac address from SPI flashRajashekhara, Sudhakar1-0/+28
DA850/OMAP-L138 EMAC driver uses random mac address instead of a fixed one because the mac address is not stuffed into EMAC platform data. This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.

Apart from the regular AM18x/DA850/OMAP-L138 SoC operating at 300MHz, these SoCs have variants that can operate at a maximum of 456MHz. Variants at 408Mhz and 375 Mhz are available as well. Not all silicon is qualified to run at higher speeds and unfortunately the maximum speed the chip can support can only be determined from the label on the package (not software readable). The EVM hardware for all these variants is the same (except for the actual SoC populated). U-Boot on the EVM sets up ATAG_REVISION to inform the OS regarding the speed grade supported by the silicon. We use this information to pass on the speed grade information to the SoC code. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-12-22da850-evm: add baseboard GPIO expander buttons, switches and LEDsBen Gardiner1-0/+187
This patch adds a pca953x platform device for the tca6416 found on the evm baseboard. The tca6416 is a GPIO expander, also found on the UI board at a separate I2C address. The pins of the baseboard IO expander are connected to software reset, deep sleep enable, test points, a push button, DIP switches and LEDs. Add support for the push button, DIP switches and LEDs and test points (as free GPIOs). The reset and deep sleep enable connections are reserved by the setup routine so that userspace can't toggle those lines. The existing tca6416-keypad driver was not employed because there was no apararent way to register the LEDs connected to gpio's on the tca6416 while simultaneously registering the tca6416-keypad instance.

2010-12-22da850-evm: add UI Expander pushbuttonsBen Gardiner1-0/+95
This patch adds EV_KEYs for each of the 8 pushbuttons on the UI board via a gpio-key device. The expander is a tca6416; it controls the SEL_{A,B,C} lines which enable and disable the peripherals found on the UI board in addition to the 8 pushbuttons mentioned above. The reason the existing tca6416-keypad driver is not employed is because there was no aparent way to keep the gpio lines used as SEL_{A,B,C} registered while simultaneously registering the pushbuttons as a tca6416-keypad instance. Some experimentation with the polling interval was performed; we were searching for the largest polling interval that did not affect the feel of the responsiveness of the buttons. It is very subjective but 200ms seems to be a good value that accepts firm pushes but rejects very light ones. The key values assigned to the buttons were arbitrarily chosen to be F1-F8.

Keep PLL0 SYSCLK3 at a constant rate of 100MHz. This enables the AEMIF timing to remain valid even as the PLL0 output is changed by cpufreq driver to save power. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-09-24davinci: introduce support for AM1x ARM9 microprocessorsSekhar Nori1-1/+1
The Sitara AM17x SoCs from TI are an OMAP-L137 pin-to-pin compatible ARM9 microprocessor offering from TI. The Sitara AM18x SoCs from TI are an OMAP-L138 pin-to-pin compatible ARM9 microprocessor offering from TI. More information about these processors available at: www.ti.com/am1x Because of their compatibiliy with OMAP-L1x, the kernel support for OMAP-L1x is fully relevant to AM1x processors. This patch updates the Kconfig prompt and help text to include the AM1x part names to help users select configurations required for these parts easily. Also, the hardware information that shows up in /proc/cpuinfo is updated to show applicability of the respective OMAP-L1x EVMs for AM1x parts.

The drivers on da8xx/omapl EVMs do not utilize all the channels and slots provided by EDMA. Some of these are better utilitzed by the DSP on the SoC for speeding up codec operations.

Per the da850/omap-l138 Beta EVM SOM schematic, the DEFDCDC2 and DEFDCDC3 lines are tied high. This leads to a 3.3V IO and 1.2V CVDD voltage. Pass the right platform data to the TPS6507x driver so it can operate on the DEFDCDC{2,3}_HIGH register to read and change voltage levels.

2010-07-20ASoC: davinci: let platform data define edma queue numbersSekhar Nori1-1/+1
Currently the EDMA queue to be used by for servicing ASP through internal RAM is fixed to EDMAQ_0 and that to service internal RAM from external RAM is fixed to EDMAQ_1. This may not be the desirable configuration on all platforms. For example, on DM365, queue 0 has large fifo size and is more suitable for video transfers. Having audio and video transfers on the same queue may lead to starvation on audio side. platform data as defined currently passes a queue number to the driver but that remains unused inside the driver. Fix this by defining one queue each for ASP and RAM transfers in the platform data and using it inside the driver. Since EDMAQ_0 maps to 0, thats the queue that will be used if the asp queue number is not initialized. None of the platforms currently utilize ping-pong transfers through internal RAM so that functionality remains unchanged too. This patch has been tested on DM644x and OMAP-L138 EVMs. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This patch implements the following: - interrupt initialization uses ioremap() instead of passing a virtual address via davinci_soc_info. - machine definitions directly point to cp_intc_init() or davinci_irq_init() - davinci_intc_type and davinci_intc_base now get initialized in controller specific init functions instead of davinci_common_init() - minor fix in davinci_irq_init() to use intc_irq_num instead of DAVINCI_N_AINTC_IRQ Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-05-06Davinci: cpintc host map configurationCyril Chemparathy1-1/+1
Host map configuration instructs the interrupt controller to route interrupt channels to FIQ or IRQ lines. Currently, DA8xx family of devices leave these registers at their reset-default values. TNETV107X however does not have sane reset defaults, and therefore this architecture needs to reconfigure the host-map such that channels 0 and 1 go to FIQ, and the remaining channels raise IRQs. This patch adds an optional host map argument to cp_intc_init() for this. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
