2020-04-28ARM64: fsl-imx8qm-ixora: fix iomuxc pin muxingMax Krummenacher
The iomuxc pinctrl-0 property is set with pinctrl nodes muxed for potential user space use in the module specific device tree. In order to keep them copy the full list here and amend the additional pinctrl_uart24_forceoff. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") changed many more clocks than only the SPDIF core clock as stated in the commit message. The MLB clock has been added and this causes SPDIF regression as reported by Xavi Drudis Ferran and also in this forum post: https://forum.digikey.com/thread/34240 The MX6Q Reference Manual does not mention that MLB is a clock related to SPDIF, so change it back to a dummy clock to restore SPDIF functionality.

2020-03-09ARM: mach-imx6q: add ksz9131rn_phy_fixupPhilippe Schenker
The MAC of the i.MX6 SoC is compliant with RGMII v1.3. The KSZ9131 PHY is like KSZ9031 adhering to RGMII v2.0 specification. This means the MAC should provide a delay to the TXC line. Because the i.MX6 MAC does not provide this delay this has to be done in the PHY. This patch adds by default ~1.4ns delay to the TXC line. This should be good for all boards that have all RGMII signals routed with the same length. The KSZ9131 has relatively high tolerances on skew registers from MMD 2.4 to MMD 2.8. Therefore the new DLL-based delay of 2ns is used and then as little as possibly subtracted from that so we get more accurate delay. This is actually needed because the i.MX6 SoC has an asyn skew on TXC from -100ps to 900ps. Related-to: ELB-1299 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
