MLK-9678 arm: imx6: switch to analog bypass before entering DSM
this patch implements the workaround for ERR005852:
ERR005852 Analog: Transition from Deep Sleep Mode to LDO Bypass
Mode may cause the slow response of the VDDARM_CAP output.
Normally, the VDDARM_CAP supply takes only approximately 40 us
to raise to the correct voltage when exiting from Deep Sleep(DSM)
mode, if the LDO is enabled. If the LDO bypass mode is selected,
the VDDARM_CAP supply voltage will drop to approximately 0V when
entering and when exiting from DSM,even though the VDDARM_IN
supply is already stable, the VDDARM_CAP supply will take about
2 ms to rise to the correct voltage.
software workaround:
if internal LDO bypass, switch to analog bypass mode(0x1E), prior
to entering DSM, and then, revert to the normal bypass mode, when
exiting from DSM.

ENGR00301115 net: fec_ptp: fix convergence issue to support IXXAT and LinuxPTP stack
IEEE 1588 module has one hw issue in capturing the ATVR register. According
to the user manual it is:
ENET0->ATCR |= ENET_ATCR_CAPTURE_MASK;
while(ENET0->ATCR & ENET_ATCR_CAPTURE_MASK);
ts_counter_ns = ENET0->ATVR;
Incorrect behavior for ENET_ATCR[Capture and Restart Bits]. These bits will always
read a value zero. According to SPEC, when these bits are set to 1'b1, these should
hold value 1'b1 until the counter value is capture in the register clock domain.
Unfortunately there is a bug with the way the bit "ENET_ATCR_CAPTURE" clears.
So need something like:
ENET0->ATCR |= ENET_ATCR_CAPTURE_MASK;
wait();
ts_counter_ns = ENET0->ATVR;
The wait-time to be at least 6 clock cycle of the slower clock between the register
clock and the 1588 clock. The 1588 ts_clk is 25Mhz, register clock is 66Mhz, so the
wait-time must be greater than 240ns (40ns * 6). The workaround is that adding 1us
delay before read ATVR.
