* mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam2016-09-06-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed. Keep all the mx6 SPL users in their current REF_SEL and REFR values, so no functional changes for the existing users.

* imx: ventana: add dt fixup for watchdog external resetTim Harvey2016-07-28-0/+30
| | | | | | | | | | | Added removal of the fsl,ext-reset-output property in the wdog node for board revisions that pre-date the addition of the external watchdog reset signal. This property is a recent addition to mainline linux kernel in order to specify that the IMX watchdog external reset should be used instead of the internal chip-level reset.

* imx: ventana: add dt fixup for GW16082 irq mappingTim Harvey2016-07-28-0/+228
| | | | | | | | | | | | | | The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned in the reverse order according to the PCI spec. If the TI bridge is found on the Ventana PCI bus, add device-tree nodes according to bus enumeration explicitly defining the interrupt mapping to override the default PCI mapping in the Linux kernel. This allows the GW16082 to work with upstream kernels that support device-tree irq parsing. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

| * imx: ventana: add fdt fixup to enable UHS-I support on selected boardsTim Harvey2016-05-31-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UHS-I support is available on Ventana boards with micro-SD sockets depending on the board revision. For backwards compatibility to not break users who have old bootloaders and newer kernels the device-tree on boards with microSD disables UHS-I support by default by defining the no-1-8-v property in the esdhc controller node. For models/revisions that support switchable 1.8V/3.3V I/O which is detectable by the presence of a pull-down on the SD3_VSELECT pin we remove that property to enable support in the kernel. Additionally we add SD3_VSELECT to the pinmux for clarity (even though U-Boot does not currently support UHS-I modes requiring 1.8V I/O). Signed-off-by: Tim Harvey <tharvey@gateworks.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removed several EEPROM bit dependencies: - for dt aliases that don't exist and thus don't ever do anything (pcie,lvds1,uart*,vpu,csi*,hdmi_in,hdmi_out,cvbs_in,cvbs_out,gps) - for features that don't effect bus ordering or have no detrimental affect if erroneously enabled when not present (ahci,nand,i2c*) - for features that have little to no impact on being erroneously enabled but high impact if erroneously disabled (can*, spi*) - for features that have an high adverse affect of not being set when they should and no adverse affect of being set when they shouldn't (ipu*). Removing these means the following: - these no longer are supported with the econfig command - these no longer affect the device-tree in any way Signed-off-by: Tim Harvey <tharvey@gateworks.com>
| * imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bitTim Harvey2016-05-31-11/+22
| | | | | | | | | | | | | | | | | | | | | | The MSATA feature is a board-specific feature on Gateworks Ventana boards. In most cases a 2:1 mux will steer either PCIe or SATA to a miniPCIe socket through an MSATA_EN gpio. In these such cases assign the gpio in the board specific struct and use its presence to determine if we default the GPIO to PCIe and if we later steer it according to hwconfig.

| * imx: ventana: enable pwm device-tree property based on hwconfigTim Harvey2016-05-31-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | Most Ventana boards have a connector with off-board digital-I/O signals including some that can be pinmuxed as either a PWM or a GPIO. The hwconfig env variable is used to configure these and they will be pinmuxed according to this configuration in the bootloader. This patch adds a device-tree fixup that will enable the pwm controller nodes appropriately for digital-I/O's that are configured as pwm via hwconfig so that the pin can be used with the Linux kernel /sys/class/pwm API.
