* imx_common: check for Serial Downloader in spl_boot_deviceStefano Babic2016-01-03-0/+59
| | | | | | | | | | | | | | | | | | | Check for bmode before reading the boot device to check if a serial downloader is started, and returns UART if the serial downloader is set, letting SPL to wait for an image if CONFIG_SPL_YMODEM_SUPPORT is set. This allows to load again a SPL based board with imx_usb_loader together with a tool such as kermit.

* ARM: mxs: allow boards to select DC-DC switching clock sourceMichael Heimpold2016-01-03-0/+36
| | | | | | | | | | | | | | | | | | | | | For some board designs, it might be useful to switch the DC-DC clock source to something else rather the default 24 MHz, e.g. for EMI reasons. For this, override the mxs_power_setup_dcdc_clocksource function in your board support files. Example: void mxs_power_setup_dcdc_clocksource(void) { mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ); } Signed-off-by: Michael Heimpold <mhei@heimpold.de> Cc: Marek Vasut <marex@denx.de> Cc: Otavio Salvador <otavio@ossystems.com.br> Cc: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Marek Vasut <marex@denx.de>
* cgtqmx6eval: fix pad configuration for SPI busMichael Schanz2016-01-03-1/+1
| | | | | | | | | | | | | Use the macro SETUP_IOMUX_PAD(...) rather than imx_iomux_v3_setup_multiple_pads(...) in order to setup the pin configuration for ECSPI1. ARRAY_SIZE(pads) provides the wrong size for imx_iomux_v3_setup_multiple_pads(pads, ARRAY_SIZE(pads)) in case of MX6QDL. In the particular case, the content of GPR12 is overwritten and the IPG/AHB/ATB/ATP clocks are deactivated. Therefore, the connection to the system via JTAG is not possible anymore. Furthermore, kernel version 3.0.35 hangs during bootprocess in the function etm_init(). Signed-off-by: Michael Schanz <michael.schanz@congatec.com> Acked-by: Otavio Salvador <otavio@ossystems.com.br>

* net: fec_mxc: configure MDIO hold timeMåns Rullgård2016-01-03-3/+15
| | | | | | | | | | | | If the host clock frequency is higher than 100 MHz, the MDIO hold time needs to be increased from its current setting of one cycle in order to meet the specified minium of 10 ns. Writing an appropriate value to the HOLDTIME field of the MII_SPEED register achieves this. Comment copied from Linux kernel.

* ARM: imx: fsl_esdhc: fix usage of low 4 bits of sysctl registerEric Nelson2016-01-03-2/+15
| | | | | | | | | | | | | | | | | | | | | | The low four bits of the SYSCTL register are reserved on the USDHC controller on i.MX6 and i.MX7 processors, but are used for clocking operations on earlier models. Guard against their usage by hiding the bit mask macros on those processors. These bits are used to prevent glitches when changing clocks on i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7. >From the i.MX6DQ RM: To prevent possible glitch on the card clock, clear the FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS or DVS in System Control Register) or setting RSTA bit.

* ARM: mxs: fix VDDD brownout settingMichael Heimpold2015-12-01-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment, the desired brownout is at 1.0V. However, this setting cannot be realized by hardware since we have only 3 bits to represent the voltage difference from the target value. Target value is 1500 mV, brownout target is 1000 mV, voltage steps are 25 mV. Register content calculation: (1500 [mV] - 1000 [mV]) / 25 [mV] = 20 (decimal) = 0x14 Register takes only 3 bits, that is 0x4. But 0x4 * 25 [mV] = 100 [mV], that means that actual brownout level is 1500 [mV] - 100 [mV] = 1.4 V. Minimum possible BO level is 1500 [mV] - 0x7 * 25 [mV] = 1315 [mV]. So lets use this value as desired BO value (which is also the same as FSL bootlets use).

It can be checked later in the test if required. It is possible that this may prove useful for non-test situations.
