Davinci's MDIO controller is present on other TI devices, without an accompanying EMAC. For example, on tnetv107x, the same MDIO module is used in conjunction with a 3-port switch hardware. By separating the MDIO controller code into its own platform driver, this patch allows common logic to be reused on such platforms.

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.

Setup NAND flash timing on DM6467T EVM. Without the timing setup, the NAND flash on DM6467T RevC EVM reports a number of random bad blocks because of read errors.

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.

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.

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: NSekhar Nori <nsekhar@ti.com> Acked-by: NKevin Hilman <khilman@deeprootsystems.com> Signed-off-by: NKevin Hilman <khilman@deeprootsystems.com>

By default the audio driver uses EDMAQ_0 as the DMA queue, but on DM365 this queue is specially designed for video transfers with a large fifo size. Having both audio and video transfers on the same queue leads to noise on the audio side. This patch changes the audio queue number for DM365 to EDMAQ_3.

On OMAP-L138 SoC, some of the sysclks need not be at a fixed ratio to CPU clock and can be kept at a relatively constant rate by adjusting the PLLDIVn ratio even as cpufreq goes ahead and changes the CPU clock. This feature can be used to keep the EMIFA (PLL0 SYSCLK3) clock at a constant rate so that the EMIF timings need not be re-programmed whenever the CPU frequency changes.

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.

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.

"param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function.
