| * clk: socfpga: add arria10 clk driversSteffen Trumtrar2017-05-036-1/+572
| | | | | | | | | | | | | | | | | | | | | | Arria10 has a (slightly) different clock controller than the Cyclone5. Add new drivers for it. This driver only reads out the setup and builds the clocktree, it does not setup any clocks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the device parameter functions also make the globalvar functions more consistent. This also adds support for readonly globalvars and changes several existing globalvars which should really be readonly to readonly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | param: make parameter functions more consistentSascha Hauer2017-04-1112-41/+41

With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BCH error detection and correction was only looking at the first of four syndrome polynomials, which meant it was failing to detect and correct bitflips in the last 3/4 of the data. In effect, only the first 512 bytes of a 2048 byte page were being protected by ECC. The syndrome polynomials (BCH error codes) are stored in the NAND's OOB, each of which protects 512 bytes of data. The driver used eccsteps = 1 which effectively made it only use the first polynomial, and therefore was only protecting the first 512 bytes of the page. The fix is to pull over a bit of code from the kernel's omap_correct_data() that sets eccsteps = 4 when the page size is 2048 bytes and hardware ECC is being used.

This is used by the state framework to find its backend path. This path has to be translated back to a device node when Linux is started. The current approach turned out to be too simple: We assumed that the node path is the same in the tree Linux is started with. This is not true in several cases: - partition nodes should have the name "partition@<offset>", but in several trees they have "partition@<num>" - There are two different partition bindings: The legacy binding and the new one with an additional partitions subnode which has a compatible = "fixed-partitions" property. The node path only stays the same when the internal tree uses the same bindings and node names as the tree Linux is started with. To overcome this limitation we create of_find_node_by_devpath() which converts the device path back to a device node. It does so by finding the device node of the hardware device rather than the partition node. It then parses over the partitions in this device node with the known bindings looking for a partition which matches in offset and size to the barebox partition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | With the legacy partition binding we did not modify the device node when no partition exist, but with the new binding we would create the "partitions" node with compatible = "fixed-partitions".
