Errata id: i877
Description:
------------
The RGMII 1000 Mbps Transmit timing is based on the output clock
(rgmiin_txc) being driven relative to the rising edge of an internal
clock and the output control/data (rgmiin_txctl/txd) being driven relative
to the falling edge of an internal clock source. If the internal clock
source is allowed to be static low (i.e., disabled) for an extended period
of time then when the clock is actually enabled the timing delta between
the rising edge and falling edge can change over the lifetime of the
device. This can result in the device switching characteristics degrading
over time, and eventually failing to meet the Data Manual Delay Time/Skew
specs.
To maintain RGMII 1000 Mbps IO Timings, SW should minimize the
duration that the Ethernet internal clock source is disabled. Note that
the device reset state for the Ethernet clock is "disabled".
Other RGMII modes (10 Mbps, 100Mbps) are not affected
Workaround:
-----------
If the SoC Ethernet interface(s) are used in RGMII mode at 1000 Mbps,
SW should minimize the time the Ethernet internal clock source is disabled
to a maximum of 200 hours in a device life cycle. This is done by enabling
the clock as early as possible in IPL (QNX) or SPL/u-boot (Linux/Android)
by setting the register CM_GMAC_CLKSTCTRL[1:0]CLKTRCTRL = 0x2:SW_WKUP.
So, do not allow to gate the cpsw clocks using ti,no-idle property in
cpsw node assuming 1000 Mbps is being used all the time. If someone does
not need 1000 Mbps and wants to gate clocks to cpsw, this property needs
to be deleted in their respective board files.

For USB gadget on port A (device mode):
- pin PA31 is configured as an input GPIO which triggers an interrupt when
vbus is detected on USB port A.
- pin PB9 is configured as an output GPIO and set to low level so the
board doesn't supply vbus to USB port A.
For USB host:
- pin PB10 is configured as an output GPIO and is active at high level.
The ohci driver will activate this pin so the board supplies vbus to USB
port B.
- pin PB9 should be configured as an output GPIO and active at high level
to use to USB port A in host mode (conflicts with USB gadget).

In the final versions of the Porter board (called "PORTER_C") Renesas
decided to get rid of the Maxim Integrated MAX3355 OTG chip and didn't
add any other provision to differ the host/gadget mode, so we'll have to
remove no longer valid "renesas,enable-gpio" property from the HS-USB

All pinctrl nodes for the Atmel pinctrl controller need to have their
bias configuration explicitly defined. Otherwise, the pinctrl mapping
is not valid.
It works for now as the pinctrl driver proceeds even with invalid
mappings, but this can become an issue, if the pinctrl driver starts
to require valid mappings. Additionally, the pin is not protected from
being remapped later by an other driver.
There is an external 1kOhms pull-up to 3.3V, so no bias is required on
the Ethernet PHY's interrupt line.

After adding cpufreq-dt support to Exynos542x, the Odroid XU3-Lite can
be easily overheated when launching eight CPU-intensive tasks:
thermal thermal_zone3: critical temperature reached(121 C),shutting down
This seems to be specific to Odroid XU3-Lite board which officially
supports lower frequencies than regular XU3 or XU4. When working at
maximum CPU speed (1800 MHz big and 1300 MHz LITTLE) in warmer place for
longer time, the fan fails to cool down the board and it reaches
critical temperature.
Add CPU cooling to Exynos5422/5800 to fix this issue. When reaching last
interrupt-driven trip-point (70 degrees of Celsius) start passive
cooling in polling mode (slowing CPU by 2 steps). When reaching 85
degrees of Celsius, start slowing even more, down to 600 MHz.
