2020-03-04dt-bindings: micrel-ksz90x1: Add rxc-dll and txc-dll propertiesPhilippe Schenker
This commit adds two properties to control the RX DLL and TX DLL 2ns delay on RXC/TXC RGMII clock lines. This is especially needed if the MAC does not provide TXC delay by itself. Related-to: ELB-1299 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2020-03-04net: phy: micrel: Add KSZ9131 rxdll txdll bypass dt propertiesPhilippe Schenker
With this patch one is able to control the rx dll and tx dll bypass bits, hence the 2ns delay on rxc and txc lines in devicetree. Related-to: ELB-1299 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2020-03-04ARM64: dts: apalis-imx8qm-v1.1: Remove RXC delay in MACPhilippe Schenker
The RXC delay is provided in both PHYs used (KSZ9031 and KSZ9131) on the PHY itself so it is not needed on the MAC. Related-to: ELB-1299 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2020-03-04ARM: 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>

2020-02-11spi: imx: Use dynamic bursts only when bits_per_word is 8, 16 or 32Maxime Chevallier
commit 2801b2f5fad3d1e9ea0ac8484584051071065645 upstream The dynamic bursts mode allows to group together multiple words into a single burst. To do so, it's necessary that words can be packed into the 32-bits FIFO entries, so we can't allow using this mode with bit_per_words different to 8, 16 or 32. This prevents shitfing out extra clock ticks for transfers with bit_per_word values not aligned on 8 bits. With that , we are sure that only the correct number of bits is shifted out at each transfer, so we don't need to mask out the remaining parts of the words.
