* | at91_udc: add DT supportSam Ravnborg2017-09-061-11/+45
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the linux kernel version of the same driver. Needs to adjust clock names as the clock names used in the device tree does not match the clocknames used in platform_data. The clocknames in the device tree are not unique, so it was not an option to rename the clocks. It boots and the driver is discovered - no further testing done. $ devinfo fff78000.gadget Resources: num: 0 name: /ahb/apb/gadget@fff78000 start: 0xfff78000 size: 0x00004000 Driver: at91_udc Bus: platform Parameters: vbus: 1 (type: bool) Device node: /ahb/apb/gadget@fff78000 gadget@fff78000 { compatible = "atmel,at91sam9263-udc"; reg = <0xfff78000 0x4000>; interrupts = <0x18 0x4 0x2>; clocks = <0x26 0x27>; clock-names = "pclk", "hclk"; status = "okay"; atmel,vbus-gpio = <0x28 0x19 0x0>; }; Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * param: make parameter functions more consistentSascha Hauer2017-04-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. 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>

|/ | | | | | | | | | | | | | | | | fixes: 81737c1 mtd: Fix erasing of devices >4GiB Several places erased a complete flash partition passing ~0 as count to erase(). With the above commit count to erase was changed from an unsigned type to a signed type, so the (count > f->size - offset) check in erase() no longer triggers and the ~0 count is no longer adjusted to the whole device size. Among other things this results in saveenv failures on NOR flashes. This patch fixes this by introducing an explicit macro for erasing the whole device which is tested for in erase().

This only makes sense for flash commands where the target file is a mtd device. If we just want to transfer a UBI image we would expect a simple copy to the correct location. This patch checks if the destination file is a MTD device by opening it and calling an ioctl MEMGETINFO. Only for MTD devices, ubiformat is called.

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.
