* fdt: cros_ec: Drop compatible string in fdtdecSimon Glass2015-04-18-2/+0
| | | | | | This is not needed now that we have moved to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
* cros_ec: Remove unused cros_ec_board_init() functionSimon Glass2015-04-18-12/+0
| | | | | | Now that driver model handles cros_ec init, we can drop this special code. Signed-off-by: Simon Glass <sjg@chromium.org>
* exynos: cros_ec: Drop unnecessary initSimon Glass2015-04-18-16/+0
| | | | | | | Since driver model will probe the EC when it is first used, we do not need to init it explicitly. Signed-off-by: Simon Glass <sjg@chromium.org>

* cros_ec: Reinit the cros_ec device when 'crosec init' is usedSimon Glass2015-04-18-2/+8
| | | | | | | This command is supposed to reinit the device. At present with driver model is does nothing. Implement this feature. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: cros_ec: Convert cros_ec LPC driver to driver modelSimon Glass2015-04-18-0/+51
| | | | | | | This is the last driver to be converted. It requires an LPC bus and a special check_version() method. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: chromebook_link: dts: Add PCH and LPC devicesSimon Glass2015-04-18-34/+55
| | | | | | | | | | | | The PCH (Platform Controller Hub) is on the PCI bus, so show it as such. The LPC (Low Pin Count) and SPI bus are inside the PCH, so put these in the right place also. Rename the compatible strings to be more descriptive since this board is the only user. Once we are using driver model fully on x86, these will be dropped.

* dm: x86: Add a uclass for an Low Pin Count (LPC) deviceSimon Glass2015-04-18-0/+30
| | | | | | | | | On x86 systems this device is commonly used to provide legacy port access. It is sort-of a replacement for the old ISA bus. Add a uclass for this, and allow it to have child devices. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: x86: Add a uclass for a Platform Controller HubSimon Glass2015-04-18-9/+29
| | | | | | | | | Add a simple uclass for this chip which is often found in x86 systems where the CPU is a separate device. The device can have children, so make it scan the device tree for these. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: x86: spi: Convert ICH SPI driver to driver modelSimon Glass2015-04-18-278/+290
| | | | | | | | | | | | Convert this driver over to use driver model. Since all x86 platforms use it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent code and remove the old x86 spi_init() function. Note that this does not make full use of the new PCI uclass as yet. We still scan the bus looking for the device. It should move to finding its details in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: sf: Add driver model read/write/erase methodsSimon Glass2015-04-18-6/+57
| | | | | | | | Permit use of a udevice to talk to SPI flash. Ultimately we would like to retire the use of 'struct spi_flash' for this purpose, so create the new API for those who want to move to it. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: Improve error handlingJoe Hershberger2015-04-18-19/+70
| | | | | | | | | | | | Take a pass at plumbing errors through to the users of the network stack Currently only the start() function errors will be returned from NetLoop(). recv() tends not to have errors, so that is likely not worth adding. send() certainly can return errors, but this patch does not attempt to plumb them yet. halt() is not expected to error.

* sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger2015-04-18-5/+218
| | | | | | | | | | | | | | | The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

| | | | | | | | | | | | | | | netretry previously would only retry in one specific case (your MAC address is not set) and no other. This is basically useless. In the DM implementation for eth it turns this into a completely useless case since an un-configured MAC address results in not even entering the NetLoop. The behavior is now changed to retry any failed command (rotating through the eth adapters if ethrotate != no). It also defaulted to retry forever.
