2015-04-23dm: core: Select device tree control correctly for SPLSimon Glass
Some boards will not use device tree for SPL even with driver model. Add the logic to support this. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23dm: core: Drop device removal error path when not supportedSimon Glass
When CONFIG_DM_DEVICE_REMOVE is not enabled, such as in SPL, we cannot remove or unbind devices and do not expect to get errors when binding and probing devices. So drop the error path to reduce code size. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23dm: Add a panic_str() function to reduce code sizeSimon Glass
The printf() in panic() adds about 1.5KB of code size to SPL when compiled with Thumb-2. Provide a smaller version that does not support printf()-style arguments and use it in two commonly compiled places. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23dm: core: Remove unbind operations when not requiredSimon Glass
The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing devices. It should also remove the 'unbind' code since if we cannot remove we probably don't need to unbind. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23dm: core: Allow sequence alias support to be removed for SPLSimon Glass
In many cases SPL only uses a single serial port and there is no need for alias sequence support. We will just use the serial port pointed to by stdout-path in the /chosen node. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23serial: ns16550: Remove unnecessary init on UART setupSimon Glass
It is not necessary to write a zero baud rate to the device, and for some chips this will cause problems. Drop this code. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23dm: ns16550: Support non-byte register spacing with driver modelSimon Glass
Allow this driver to support boards where the register shift is not 0. This fixes some compiler warnings which appear in that case. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-23serial: ns16550: Add an option to specify the debug UART register shiftSimon Glass
This UART permits different register spacing. To support the debug UART on devices which have a spacing other than 1 byte, allow the shift value to be specified. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-04-22dm: core: Handle recursive unbinding of uclass devicesSimon Glass
Since a device can have children in the same uclass as itself, we need to handle unbinding carefully: we must allow that unbinding a device in a uclass may cause another device in the same uclass to be unbound. Adjust the code to cope. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com> Tested-by: Joe Hershberger <joe.hershberger@ni.com>
2015-04-22dm: core: remove type 'static' of function uclass_get_device_tail()Przemyslaw Marczak
Uclass API provides a few functions for get/find the device. To provide a complete function set of uclass-internal functions, for use by the drivers, the function uclass_get_device_tail() should be non-static.

This commit extends the driver model uclass's API by function: - uclass_get_device_by_name() And this function returns the device if: - uclass with given ID, exists, - device with exactly given name(dev->name), exists, - device probe, doesn't return an error. The returned device is activated and ready to use. Note: This function returns the first device, which name is equal to the given one. This means, that using this function you must assume, that the device name is unique in the given uclass's ID device list.

The returned device is not activated - need to be probed before use. Note: This function returns the first device, which name is equal to the given one. This means, that using this function you must assume, that the device name is unique in the given uclass's ID device list. uclass-internal.h: cleanup - move the uclass_find_device_by_seq() declaration and description, near the other uclass_find*() functions.

This commit adds 'uclass_platdata' field to 'struct udevice', which can be automatically allocated at bind. The allocation size is defined in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'. New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used for memory freeing at device unbind method.

2015-04-21serial: pl01x: fix PL010 regressionLinus Walleij
commit aed2fbef5e9a0ab5a7cd01e742039a962f0b24ef "dm: serial: Tidy up the pl01x driver" caused a regression on (real hardware) PL010 by omitting to update the line control register when switching baudrate. Fix this by inlining the missing write to the baud control register. Also renaming the set_line_control() function to pl011_set_line_control() since this function is clearly PL011-specific, and it won't suffice to call that to set up line control. Tested on the Integrator/AP hardware. Cc: Simon Glass <sjg@chromium.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2015-04-20net: phy: realtek: Disable interrupt on Realtek Ethernet PHY driversCodrin Ciubotariu
Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have interrupts enabled by default. If the interrupt is not treated later by the OS and the PHY's interrupt line is enabled and shared with other interrupts, the system will get an interrupt storm. This patch disables the interrupt for PHY devices that use one of the current Realtek Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L) have the interrupt masked. In this case, the functionality of the PHY should not be afected since this patch brings INER and INSR registers to their default values.

2015-04-20MPC8541/MPC8555: Enable SS_EN in DDR_SDRAM_CLK_CNLT registerCurt Brune
According to the MPC8555/MPC8541 reference manual the SS_EN (source synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set during initialization. >From section 9.4.1.8 of that manual: Source synchronous enable. This bit field must be set during initialization. See Section 9.6.1, "DDR SDRAM Initialization Sequence," details. 0 - Reserved 1 - The address and command are sent to the DDR SDRAMs source synchronously. In addition, Freescale application note AN2805 is also very clear that this bit must be set. This patch reverts a change introduced by commit 457caecdbca3df21a93abff19eab12dbc61b7897. Testing Done: Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS and inspected the generated assembly code to verify the SS_EN bit was being set. There is one extra instruction emitted: fff9b774: 65 29 80 00 oris r9,r9,32768 Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no additional instructions were emitted related to this patch.

2015-04-18dm: net: Tidy up designware driver ready for driver modelSimon Glass
Adjust the error handling to use errno.h instead of returning -1. Change leaf functions to pass in the arguments they require rather than struct eth_device. Apart from simplifying the code it makes is easier to reuse these functions for driver model, since mostly they actually only use struct dw_eth_priv (which we can keep). Create a stub for each Ethernet operation function. This will allow use to share code with the driver model versions.
