2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>

2010-09-24davinci: introduce support for AM1x ARM9 microprocessorsSekhar Nori
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.

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>

2010-05-06Davinci: 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>

is selected On the DA830, AEMIF and MMC/SD pins are shared. On the EVM, when the mux_mode signal is low MMC/SD works and when mux_mode signal is high, NAND works.
