* davinci: Initial support for MityDSP-L138/MityARM-1808Michael Williamson2010-09-24
| | | | | | | | | | | | | This patch adds initial support for the MityDSP-L138 and MityDSP-1808 system on Module (SOM) under the machine name "mityomapl138". These SOMs are based on the da850 davinci CPU architecture. Information on these SOMs may be found at http://www.mitydsp.com. Basic support for the console UART, NAND, and EMAC (MII interface) is included in this patch.

| | | | | | | | | | This patch adds machine checks in the serial console init routines for the DA8XX EVM boards.

* davinci: dm644x evm: setup NAND flash timingSekhar Nori2010-09-24
| | | | | | | | | | | | | | | | | | The DM644x EVM nand flash timing was earlier being done as a special case in the NAND driver itself. With the NAND driver now capable of progamming the AEMIF interface using timing data passed from the platform, the timing values are being moved into their rightful place in the EVM specific board file. The values being programmed match what was being done earlier and thus do not represent any change in performance/functionality.

* nand: davinci: add support for timing configurationSekhar Nori2010-09-24
| | | | | | | | | | | | | | | | | | | | | This patch modifies the DaVinci NAND driver to use the new AEMIF timing setup API to configure the NAND access timings. Earlier, AEMIF configuration was being done as a special case for DM644x board, but now more boards emerge which have capability to boot for other media (SPI flash, NOR flash) and have the kernel access NAND flash. This means that kernel cannot always depend on the bootloader to setup the NAND. Also, on platforms such as da850/omap-l138, the aemif input frequency changes as cpu frequency changes; necessiating re-calculation of timimg values as part of cpufreq transtitions. This patch forms the basis for adding that support.

* davinci: add support for aemif timing configurationSekhar Nori2010-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to configure the AEMIF interface with supplied timing values. Since this capability is useful both from NOR and NAND flashes, it is provided as a new interface and in a file of its own. AEMIF timing configuration is required in cases: 1) Where the AEMIF clock rate can change at runtime (a side affect of cpu frequency change). 2) Where U-Boot does not support NAND/NOR but supports other media like SPI Flash or MMC/SD and thus does not care about setting up the AEMIF timing for kernel to use. 3) Where U-Boot just hasn't configured the timing values and cannot be upgraded because the box is already in the field. Since there is now a header file for AEMIF interface, the common (non-NAND specific) defines for AEMIF registers have been moved from nand.h into the newly created aemif.h Signed-off-by: Sekhar Nori <nsekhar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | Current cpufreq code does not consider errors that can occur while changing voltage. Code to increase CPU frequency goes ahead even in the case the regulator has failed to increase the voltage. This leads to hard error since lower voltages cannot support increased frequency. Prevent this by not increasing frequency in case increasing voltage is not successful. Also, do not lower the voltage if changing the cpu frequency has failed for some reason. Note that we do not return error on failure to decrease voltage as that is not a hard error. Build fix for non-cpufreq kernels by Caglar Akyuz.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current EDMA driver is not taking care of EDMA channels/slots which are allocated from other processor, say DSP. If a channel/slot is allocated from DSP, the existing EDMA driver can still allocate the same resource on ARM. This patch enables the user to pass the channel/slots reserved for DSP as platform data. EDMA driver scans this list during probe and prepares a bitmap of channel/slots which can be used on ARM side. Trying to reserve channels by doing a 'pre-allocate' using edma_alloc_{slot|channel}() API does not work because 1) The reservation should be done in probe() to avoid race with other ARM side driver trying to use EDMA 2) The alloc channel API sets up the access through shadow region 0 which will be incorrect for DSP usage. It also sets up the channel <-> queue number mapping which is not required as DSP will likely do its own mapping anyway. 3) (minor) There is no API to allocate channels in bulk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TNETV107X is a Texas Instruments SOC that shares a number of common features with the Davinci architecture. Some of the key differences between traditional Davincis and this new SOC are as follow: 1. The SOCs clock architecture includes a new spread-spectrum PLL. Some elements of the clock architecture are reused from Davinci (e.g. LPSC), but the PLL related code is overridden using existing interfaces in "struct clk". 2. The MMR layout on this SOC is substantially different from Davinci. Consequently, the fixed I/O map is a whole lot more convoluted (more so than DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC, and therefore all mappings have to be through ioremap().

| | * | ASoC: davinci: let platform data define edma queue numbersSekhar Nori2010-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| | * | ASoC: DaVinci: More accurate continuous serial clock for McBSP (I2S)Raffaele Recalcati2010-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2s_accurate_sck switch can be used to have a better approximate sampling frequency. The clock is an externally visible bit clock and it is named i2s continuous serial clock (I2S_SCK). The trade off is between more accurate clock (fast clock) and less accurate clock (slow clock). The waveform will be not symmetric. Probably it is possible to get a better algorithm for calculating the divider, trying to keep a slower clock as possible. This patch has been developed against the http://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci.git git tree and has been tested on bmx board (similar to dm365 evm, but using uda1345 as external audio codec).

| | * | ASoC: DaVinci: Added selection of clk input pin for McBSPRaffaele Recalcati2010-07-06
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When McBSP peripheral gets the clock from an external pin, there are three possible chooses, MCBSP_CLKX, MCBSP_CLKR and MCBSP_CLKS. evm-dm365 uses MCBSP_CLKR, instead in bmx board I have a different hardware connection and I use MCBSP_CLKS, so I have added this possibility.

* / davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied highSekhar Nori2010-07-28
|/ | | | | | | | | | | | | 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.
