2018-12-20phy: ksz9031: Center FLP timing at 16msPhilippe Schenker
This patch centers the timing around 16ms instead of 8ms as it is in reset. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2018-12-20board: imx6ull: Add disable PMIC_STBY_REQPhilippe Schenker
Disable output driver of PAD CCM_PMIC_STBY_REQ. This prevents the SOC to request for a lower voltage during sleep. This is necessary because the voltage is changing too slow for the SOC to wake up properly.

2018-09-20mx6: ddr: pass mx6_ddr_sysinfo to calibration routinesEric Nelson
The DDR calibration routines have scattered support for bus widths other than 64-bits: -- The mmdc_do_write_level_calibration() routine assumes the presence of PHY1, and -- The mmdc_do_dqs_calibration() routine tries to determine whether one or two DDR PHYs are active by reading MDCTL. Since a caller of these routines must have a valid struct mx6_ddr_sysinfo for use in calling mx6_dram_cfg(), and the bus width is available in the "dsize" field, use this structure to inform the calibration routines which PHYs are active. This allows the use of the DDR calibration routines on CPU variants like i.MX6SL that only have a single MMDC port.

2018-06-18colibri-vf: use leveling evaluated by DDR validation toolsStefan Agner
The DDR validation tool (which is part of Processor Expert) allows to evaluate leveling parameters for CR105/CR106/CR110. Several runs have been made with Colibri VF50 and VF61 and it seems to evaluate very similar values. Use this values by default. Note: The newly evaluated parameters seem to require CTLUPD_AREF to be enabled! Note 2: The tool also evaluated 6 as a new value for PHY02/18 GATE_CFG (Coarse adjust of gate open time).

The pad SAI1_RX_DATA can be used as second chip select for dual-die NAND. However, with an assembly option the pad is available as GPIO on SODIMM 169.
