In mmc_davinci_xfer_done() function data direction variable is being modified before the call to davinci_abort_dma(). But inside the davinci_abort_dma() function data direction variable is being checked to select the channel to abort. Without this patch, davinci_abort_dma() function always aborts, TX channel dma.

This patch adds support for MMC/SD controller driver for all DaVinci family SoC. This patch supports davinci family SoC's DM6446, DM355, DM365 and DA830/OMAPL137. The patch has been tested on DM355 EVM.

Staging: panel: Add support for TI CLCD interface On TI DA850/OMAP-L138 EVM, HD44780 (24x2) LCD panel is being used[1], but it is interfaced through the SoC specific LCD interface and not through parallel port. A parallel port driver has been developed which interfaces to the panel driver through the SoC specific LCD interface. Basically, both the serial and parallel interfaces supported by the panel driver do not suit the specific interface SoC is supporting so, a new interface type has been introduced. Ideally the panel driver should be de-coupled from parallel and serial port related items but this patch is something that can be merged in the meantime.

TI DaVinci EMAC: delay DaVinci EMAC initialization On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI flash which is accessed using MTD interface. This patch delays the initialization of DaVinci EMAC driver by changing module_init to late_initcall. This helps SPI and MTD drivers to get initialized before EMAC thereby enabling EMAC driver to read the MAC address while booting and use it. Tested with NFS on DM644x, DM6467, DA830/OMAP-L137 and DA850/OMAP-L138 EVMs. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Reviewed-by: Chaithrika U S <chaithrika@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: David S.

Implement memory accessor interface in the MTD layer which enables the kernel to access flash data. This patch adds two new members to the mtd_partition structure, a function handler which will be called during setup of the partition and an argument to be passed to this setup function. Example: +static struct mtd_partition spi_flash_partitions[] = { + [0] = { + .name = "U-Boot", + .offset = 0, + .size = SZ_256K, + .mask_flags = MTD_WRITEABLE, + }, + [1] = { + .name = "U-Boot Environment", + .offset = MTDPART_OFS_NXTBLK, + .size = SZ_64K, + .mask_flags = MTD_WRITEABLE, + }, + [2] = { + .name = "Linux", + .offset = MTDPART_OFS_NXTBLK, + .size = SZ_7M, + .mask_flags = 0, + }, + [3] = { + .name = "MAC Address", + .offset = MTDPART_OFS_NXTBLK, + .size = SZ_64K, + .mask_flags = 0, + .setup = davinci_get_mac_addr, + .context = (void *)0, + }, +}; The davinci_get_mac_addr function reads the MAC address from offset ZERO of last MTD partition.

For best performance, codecs often setup linked triggered transfers with a contiguous block of params, and that is when this API is used. Setup/configuration of these parameter RAMs is most efficient if they are contiguous. There is an API to allocate a set of contiguous parameter RAMs and a corresponding API to free a set of contiguous parameter RAMs Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

This patch adds definitions for some DM365 IRQs that are used by the codecs. Codecs will also use the IRQs. Entries are being added to enable/disable IRQ's. There is no use as such for these entires in the kernel itself. Instead these will be used by the "linuxutils" package of the DVSDK.

On DA850/OMAP-L138 EVM, MMC/SD and NOR Flash share some of the AEMIF pins. This patch prints out a warning during booting, if both MMC/SD and NOR Flash are enabled in kernel menuconfig.

Earlier patch which adds EMAC support for da850/omap-l138 was not configuring the MDIO pins. Ethernet was working fine with the earlier patch, because the MDIO pins were configured from the boot loader. This patch removes that dependency. Also, this patch populates a member in the emac clk structure to say that EMAC LPSC sits on controller 1.

EDMA queues in DM365 are a little different than those on other DaVinci's. On DM365 Q0 and Q1 have the larger FIFO size. We want Q0 and Q1 to be used by codecs and DVSDK demos. MMC driver is the only driver which uses the flag 'EVENTQ_DEFAULT'. So MMC driver should be using Q2 instead of Q1 on DM365. This patch allows us to declare a "default queue" from SOC specific code. If it is not declared then the EDMA driver assumes a default of queue 1. Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Ethernet Media Access Controller (EMAC) on da850/omap-l138 supports 10/100 Mbps operation. It also supports Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) to physical layer (PHY). Phy which supports MII is present on the DA850/OMAP-L138 base board and Phy supporting RMII is present on the UI card. This patch adds support only for the MII Phy. Support for RMII Phy will be added later. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Add support for the DA850/OMAP-L138 Evaluation Module (EVM) from TI. The EVM has User Interface (UI) card which contains various devices. This UI card can be connected to the base board. Support for all the devices on the UI card and ones on the EVM will be added in subsequent patches. The EVM schematics are not available publicly yet; but should be available soon. A new defconfig for this board has been added mainly because the DA830/OMAP-L137 defconfig forces writethrough cache mode which is not required on DA850/OMAP-L138. This patch has been boot tested on DA850/OMAP-L138 EVM using ramdisk as filesystem.
