695df6eced UPSTREAM: ARM: dts: rockchip: move rk3036 memory definition to board files
The amount of available memory is clearly a board-specific value, so
the core per-soc dtsi should not define a default of any sort.
Therefore move the memory-nodes to the two board files.

Also fix the amount of memory on Kylin (512MB instead of 1GB).
While in most cases the bootloader will override this with the
actual amount of memory, there is no need to keep known wrong values
in the board-dts.

0955ef8f83 UPSTREAM: ARM: dts: rockchip: increase the mclk_fs to 512 for kylin board
If we playback the 8KHz FS audio with the 256 mclk_fs, we need the
mclk = 256 * 8000 = 2.048MHz, the frac div is 594 / 2.048 = 290,
the frac div value 0x00809015 set to the CRU_CLKSEL7_CON will cause
to hang.

We increase the mclk_fs to 512, will get the mclk = 512 * 8000 =
4.096MHz, use 0x01009015 instead of 0x00809015 to work around this
issue. We will keep tracking it.

b2f53d2aad UPSTREAM: ARM: dts: rockchip: support the spi for rk3036
This patch adds the needed spi node for rk3036 dts.

We have to use the 4 bus emmc to work if someone want to support
the spi devices, since the pins are re-used by emmc data[5-8] and spi.
In some caseswe need to support the spi devices, that will waste the
emmc performance.

Moment, the kylin/evb hasn't the spi devices to work, so maybe we need wait
the new required to enable in kylin/evb board.

Anyway, the spi should be needed land in rk3036 dts.

95e1e7e757 UPSTREAM: ARM: dts: rockchip: add the sdmmc for kylin board
Although We can add the sdmmc node, shouldn't enable it.
Since the sdmmc is reusing the same pin with uart2.
Unfortunately, the uart2 is used by the debug port, so that will cause
the debug information can't display on console if enabling the sdmmc.

As we have supported the sdmmc (sd card) on hardware for kylin board.
So, maybe we can have the sdmmc node in kylin dts, not to enable it.

Anyway, you only need add the okay status if someone want to enable the
sdmmc.

e.g.
if you use the adb to debug with android os.
You can add the
status = "okay" to enable the sdmmc for sd card working.
The default status is disabling it.

5f7735c704 UPSTREAM: ARM: dts: rockchip: add the sdio power sequence for kylin board
This patch adds the sdio power sequence for kylin board.
The WLAN attached to a SDIO interface, wifi/bluetooth have
reset and power been needed to enable.

AFAIK, the simple power sequence provider sets a value for multiple GPIOs.
So the reset and power of WlAN chip can be handled in mmc power sequence.
On the module itself this is one of these, that should can be handled
by reset GPIOs in simple mmc power sequence.

The Bluetooth host wake is high active from bootup, this patch is also
set pinctrl bias as the default to enable the pull up in soc internal.

can't set the status in the internal.

We should keep the default status for enable the gpio status,
In fact, the pull_none is the disable the gpio pull up/down.

3a60718b34 UPSTREAM: ARM: rockchip: add support smp for rk3036
The dual-core Cortex A7 rk3036 is a bit special in that it does not allow
to control the actual powerdomain of the cpu cores, while the rest of the
smp-bringup like reset control and entry address handling stays the same.
Its bigger sibling, the quad-core rk3128 again allows powerdomain control.

So allow that case by introducing a separate smp-enable-method, that simply
disables powerdomain handling in the common code.

Fix a typo in the driver, replace comma with a semicolon at the end

not even generate compiler warning, it was unlikely the intention.

d6fa11ae9c UPSTREAM: net: arc_emac: fix koops caused by sk_buff free
There is a race between arc_emac_tx() and arc_emac_tx_clean().
sk_buff got freed by arc_emac_tx_clean() while arc_emac_tx()
submitting sk_buff.

In order to free sk_buff arc_emac_tx_clean() checks:
    if ((info & FOR_EMAC) || !txbd->data)
        break;
    ...
    dev_kfree_skb_irq(skb);

If condition false, arc_emac_tx_clean() free sk_buff.

In order to submit txbd, arc_emac_tx() do:
    priv->tx_buff[*txbd_curr].skb = skb;
    ...
    priv->txbd[*txbd_curr].data = cpu_to_le32(addr);
    ...
    ...  <== arc_emac_tx_clean() check condition here
    ...  <== (info & FOR_EMAC) is false
    ...  <== !txbd->data is false
    ...
    *info = cpu_to_le32(FOR_EMAC | FIRST_OR_LAST_MASK | len);

In order to reproduce the situation,
run device:
    # iperf -s
run on host:
    # iperf -t 600 -c <device-ip-addr>

SoCs (RK3036) which maybe have different GRF offset, and need adjust mac
TX/RX clock.
