Commit 6770b211

 (ARM: OMAP2+: Export SoC information to userspace)
had some broken return value handling as noted by Russell King:

+       soc_dev = soc_device_register(soc_dev_attr);
+       if (IS_ERR_OR_NULL(soc_dev)) {
+               kfree(soc_dev_attr);
+               return;
+       }
+
+       parent = soc_device_to_device(soc_dev);
+       if (!IS_ERR_OR_NULL(parent))
+               device_create_file(parent, &omap_soc_attr);

This is nonsense.  For the first, IS_ERR() is sufficient.  For the second,
tell me what error checking is required in the return value of this
function:

struct device *soc_device_to_device(struct soc_device *soc_dev)
{
        return &soc_dev->dev;
}

when you've already determined that the passed soc_dev is a valid pointer.
If you read the comments against the prototype:

/**
 * soc_device_to_device - helper function to fetch struct device
 * @soc: Previously registered SoC device container
 */
struct device *soc_device_to_device(struct soc_device *soc);

if "soc" is valid, it means the "previously registered SoC device container"
must have succeeded and that can only happen if the struct device has been
registered.  Ergo, there will always be a valid struct device pointer for
any registered SoC device container.  Therefore, if soc_device_register()
succeeds, then the return value from soc_device_to_device() will always be
valid and no error checking of it is required.

Simples.  The rule as ever applies here: get to know the APIs your using
and don't fumble around in the dark hoping that you'll get this stuff
right.

Fix it as noted by Russell.

If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled
as a module, the kernel boot hangs early as the clocks for serial port
are cut while earlyprintk still uses the port.

The problem is a race between the late_initcall for omap_device (which
idles devices that have no drivers) and the late_initcall in
kernel/printk.c which turns off the earlyconsole.   Any printks
that happen between this omap_device late initcall and the earlyconsole
late initcall will crash when accessing the UART.

The fix is to ensure the omap_device initcall happens after the
earlyconsole initcall.

Commit 9fdca9df

 (spi: omap2-mcspi: convert to module_platform_driver)
broke the SPI display/panel driver probe on RX-51/N900. The exact cause is
not fully understood, but it seems to be related to the probe order. SPI
communication to the panel driver (spi1.2) fails unless the touchscreen
(spi1.0) has been probed/initialized before. When the omap2-mcspi driver
was converted to a platform driver, it resulted in that the devices are
probed immediately after the board registers them in the order they are
listed in the board file.

Fix the issue by moving the touchscreen before the panel in the SPI
device list.

The patch fixes the following failure:

[    1.260955] acx565akm spi1.2: invalid display ID
[    1.265899] panel-acx565akm display0: acx_panel_probe panel detect error

Commit ff5c9059

 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells
property) updated the number of interrupt cells required for configuring
gpios as interrupts for other devices (such as ethernet controllers).
This update allowed the interrupt type (edge, level, etc) to be
configured via device-tree (as described in the
Documentation/devicetree/bindings/gpio/gpio-omap.txt).

This broke ethernet support on the OMAP4 SDP board that defines a gpio
as the ethernet IRQ because the interrupt type (level, edge, etc) was
not getting configured correctly. This board use the ks8851 ethernet
chip which has an active low interrupt. Fix this by defining the gpio
interrupt as active-low in the device-tree binding.

Please note that the OMAP4-VAR-SOM also uses the same ethernet
controller and it is expected it will have the same problem. So the
same fix is also applied to this board.
