* ARM: at91: Move mci platform data to include/Sascha Hauer2020-05-081-10/+1
| | | | | | | | To be able to add the Atmel mci driver to COMPILE_TEST move the definition of struct atmel_mci_platform_data to include/ where it can be reached from foreign SoCs as well. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Phytec phyFLEX i.MX6: delete wrong memory nodeSascha Hauer2020-04-301-4/+1
| | | | | | | | | | | | | | The phyFLEX i.MX6 has two memory nodes in the device tree. /memory comes from the barebox dtsi file and contains dummy values. This is unnecessary, barebox will create a memory node when booting the kernel. The other one comes from the Kernel dtsi and causes more harm. The memory in the node has a size of 2GiB. Not all boards have so much memory, since 8226f7f909 ("of: base: parse all available memory nodes") this node is no longer ignored and now all boards are assumed to have 2GiB of memory. Remove the node using /delete-node/ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reviewed-by: Stefan Riedmüller <s.riedmueller@phytec.de>

* ARM: dts. i.MX7: add stopgap solution for barebox UART clock breakageAhmad Fatoum2020-04-204-0/+49
| | | | | | | | | | | | | | | | | | | | | | Commit 8b2104d740 ("driver: Call of_clk_set_defaults for each probed device") made barebox act on the assigned-clock-parents property everywhere, not only for clock provider nodes. This breaks at least the serial console on the i.MX7 SabreSD board; only garbage is output if the patch is not reverted. As stopgap measure, override these properties for all enabled uart nodes in the barebox i.MX7 device tree. This reverts the behavior to what it was like before the offending commit. This is of course no real solution, as obviously Linux was fine dealing with these properties before. But this hack should at least fix the serial console for the boards that were broken in v2020.03.0. When a proper fix follows, this patch can be reverted.

This was mostly due to unwillingness on my part to understand the code enough for porting them and because I deemed them unnecessary to support in barebox. The former has changed and the latter is not totally true as audio PLL derived clocks may be muxed as inputs for programmable and generated clocks. Port them over and mimize the diff to upstream.
