| * | | | ARM: i.MX6 Wandboard Quad: fix PBL UART MUXAlexander Kurz2017-06-131-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three variants of the Wandboard exist: WBSOLO, WBDUAL and WBQUAD. For all variants, the external serial port is connected to UART1 via PAD_CSI0_DATA10 (TX) and PAD_CSI0_DATA11 (RX). Unfortunately, the IOMUX register adresses for this mux differ between i.MX6Q (WBQUAD) and others. Make the UART IOMUX for PBL compatible for WBQUAD.

| * | | | ARM: i.MX6 Wandboard: dont do MMDC Write Leveling CalibrationAlexander Kurz2017-06-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware requirements to perform a write leveling calibration are not fulfilled by the Wandboard modules. IMX6DQRM §44.11.6 "Write leveling Calibration" Note2 states that the first bit of each data byte group (D0, D8, ..., D56) from memory must be connected to the same data bus bit on the controller, which is not given on the Wandboard modules, resulting in unpredictable calib results and breaking the WBQUAD 2GiB SDRAM setup. Similar restrictions exist for the i.MX6SD. Remove this calibration and use the MPWLDECTRL defaults.

| * | | | i.MX: fec: add post PHY reset delay DT propertyMichael Grzeschik2017-06-071-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PHY require to wait for a bit after the reset GPIO has been toggled. This adds support for the DT property `phy-reset-post-delay` which gives the delay in milliseconds to wait after reset. If the DT property is not given, no delay is observed. Post reset delay greater than 1000ms are invalid. Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

For readlink() lstat() must be used since we are indeed interested in the link, not the target.
