* ENGR00263305-11 imx: Move some i.MX common functions into the imx-common ↵Stefan Roese2013-05-21-0/+10
| | | | | | | | | | | | | | | | | | | | directory This patch moves the following functions into the imx-common directory: - mxs_wait_mask_set() - mxs_wait_mask_clr() - mxs_reset_block() These are currently used by i.MX28. But the upcoming GPMI NAND port for i.MX6 will also use these functions. So lets move them to a common location to re-use them.

| | | | | | | | | | This patch is to add the initial Freescale i.MX6dl sabresd board support. - The DDR script has been updated to the v1.5 version from ddr-scripts-rel commit: bfd157a Updated MX6DL and MX6DQ ARD and SabreSD scripts. - i.mx6dl sabre-sd board shared the same design with i.mx6q sabre-sd board except the SOC is different.Thus, we can use the same board file.

* spi: mxc_spi: Set master mode for all channelsFabio Estevam2013-04-13-0/+1
| | | | | | | | | | | | | | The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.

* i.MX6: consolidate pad names for multi-CPU boardsEric Nelson2013-03-07-1766/+1797
| | | | | | | | | | | Rename all i.MX6 pad declarations to MX6_PAD_x, so a board may support either i.MX6Quad/Dual (MX6Q) or i.MX6Dual-Lite/Solo (MX6DL) by including the proper header. Boards mx6qarm2, mx6qsabreauto, mx6qsabrelite, and mx6qsabresd only support MX6Q, so they include mx6q_pins.h. Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
* mx6: Disable Power Down Bit of watchdogFabio Estevam2013-02-12-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a mx6qsabresd revision C board with rev1.2 mx6q, the system gets resetted and it is not able to reach the Linux prompt. Comparing the watchdog behaviour on a revB versus revC board: - On a mx6qsabresd revB: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: WDOG ... - On a mx6qsabresd revC: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: POR So due to revC POR/watchdog circuitry whenever a watchdog occurs, it causes a POR. Clearing the PDE - Power Down Enable bit of WMCR registers fixes the problem and is also safe for all mx6 boards.

* imx-common: cpu: add imx_ddr_sizeTroy Kisky2012-11-10-0/+1
| | | | | | | | | | Read memory setup registers to determine size of available ram. This routine works for mx53/mx6x I need this because when mx6solo called get_ram_size with a too large maximum size, the system hanged. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
* mx6: soc: update get_cpu_rev and get_imx_type for mx6solo/sololiteTroy Kisky2012-11-10-1/+10
| | | | | | | | | | Previously, the same value was returned for both mx6dl and mx6solo. Check number of processors to differeniate. Also, a freescale patch says that sololite has its cpu/rev stored at 0x280 instead of 0x260. I don't have a sololite to verify. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

* mx6qsabreauto: Pass the board revision to the kernelFabio Estevam2012-10-16-0/+6
| | | | | | | | | | | The kernel from Freescale expects that the bootloader passes the board revision. Read the board revision and pass it via get_board_rev(). Without passing the board revision the kernel does not operate properly as the initialization of peripherals are different in revA versus revB boards.
