2010-08-05davinci: da8xx/omapl EVM: Specify reserved channels/slotsRajashekhara, Sudhakar
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. Reserve these channels/slots for the DSP.

2010-07-28davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied highSekhar Nori
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 Nori
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>

2010-05-13Davinci: aintc/cpintc - use ioremap()Cyril Chemparathy
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 Chemparathy
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>

When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y option, using da8xx_omapl_defconfig, some warnings are observed: WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference from the function da850_evm_setup_nor_nand() to the variable .init.data:da850_nand_pins The function da850_evm_setup_nor_nand() references the variable __initdata da850_nand_pins.

2009-11-25davinci: DA850/OMAP-L138 EVM: implement autodetect of RMII PHYSekhar Nori
Implement autodetection of RMII PHY by shifting the decision to use the RMII PHY to da850_evm_ui_expander_setup() from da850_evm_init() earlier. Without this patch, selecting RMII PHY in the UI expander menu will make the MII PHY unusable even though UI board is not connected. The actual configuration and registration of the EMAC device is delayed to device_initcall() so it happens after the UI card detection is complete. A side effect of this patch is the removal of a voilation of Documentation/SubmittingPatches section 2.2 in function da850_evm_init() Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2009-11-25davinci: RMII support for DA850/OMAP-L138 EVMChaithrika U S
DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY is enabled by proper programming of the IO Expander (TCA6416) ports. Also for RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds support for RMII PHY. This patch also adds a menuconfig option to select one or no peripheral connected to expander. Currently, sub-options in this menu are RMII and no peripheral.This menuconfig option is similar to the one present for UI card on DA830/OMAP-L137 EVM.
