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. Signed-off-by:

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.

This commit "677f970b" introduce a new macro "CONFIG_FSL_CLK" that get_clocks() should not be limited by ESDHC. But that patch missed to enable it for i.MX7. THis patch enables CONFIG_FSL_CLK to let get_clocks work. Signed-off-by:

Since commit 59370f3f ("net: phy: delay only if reset handler is registered") Ethernet is no longer functional. This commit does not have an issue in itself, but it revelead a problem with the Ethernet initialization. Fix this by calling enable_fec_anatop_clock() earlier and also by adding a 10ms reset delay as recommended in the AR8031 datasheet. Suggested-by:

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). Signed-off-by:
